    Trump’s Choices for Health Agencies Suggest a Shake-Up Is Coming

    by

    The picks to oversee public health have all pushed back against Covid policies or supported ideas that are outside the medical mainstream.A longtime leader of the anti-vaccine movement. A highly credentialed surgeon. A seven-term Florida congressman. A Fox News contributor with her own line of vitamins.President-elect Donald J. Trump’s eclectic roster of figures to lead federal health agencies is almost complete — and with it, his vision for a sweeping overhaul is coming into focus.Mr. Trump’s choices have varying backgrounds and public health views. But they have all pushed back against Covid policies or supported ideas that are outside the medical mainstream, including an opposition to vaccines. Together, they are a clear repudiation of business as usual.“What they’re saying when they make these appointments is that we don’t trust the people who are there,” said Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia and an adviser to the Food and Drug Administration.Some doctors and scientists are bracing themselves for the gutting of public health agencies, a loss of scientific expertise and the injection of politics into realms once reserved for academics. The result, they fear, could be worse health outcomes, more preventable deaths and a reduced ability to respond to looming health threats, like the next pandemic. “I’m very, very worried about the way that this all plays out,” Dr. Offit said.But other experts who expressed concerns about anti-vaccine views at the helms of the nation’s health agencies said that some elements of the picks’ unorthodox approaches were welcomed. After a pandemic that closed schools across the country and killed more than one million Americans, many people have lost faith in science and medicine, surveys show. And even some prominent public health experts were critical of the agencies’ Covid missteps and muddled messaging on masks and testing.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Leonard Hayflick, Who Discovered Why No One Lives Forever, Dies at 96

      by

      A biomedical researcher, he found that normal cells can divide only a certain number of times before they age — which, he said, explained aging on a cellular level.Leonard Hayflick, a biomedical researcher who discovered that normal cells can divide only a certain number of times — setting a limit on the human life span and frustrating would-be-immortalists everywhere — died on Aug. 1 at his home in Sea Ranch, Calif. He was 96.His son, Joel Hayflick, said the cause was pancreatic cancer.Like many great scientific findings, Dr. Hayflick’s came somewhat by accident. As a young scientist in the early 1960s at the Wistar Institute, a research organization at the University of Pennsylvania, he was trying to develop healthy embryonic cell lines in order to study whether viruses can cause certain types of cancer.He and a colleague, Paul Moorhead, soon noticed that somatic — that is, nonreproductive — cells went through a phase of division, splitting between 40 and 60 times, before lapsing into what he called senescence.As senescent cells accumulate, he posited, the body itself begins to age and decline. The only cells that do not go into senescence, he added, are cancer cells.As a result of this cellular clock, he said, no amount of diet or exercise or genetic tweaking will push the human species past a life span of about 125 years.This finding, which the Nobel-winning virologist Macfarlane Burnet later called the Hayflick limit, ran counter to everything scientists believed about cells and aging — especially the thesis that cells themselves are immortal, and that aging is a result of external causes, like disease, diet and solar radiation.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Fauci Speaks His Mind on Trump’s Rages and Their ‘Complicated’ Relationship

      by

      In a new book, Dr. Anthony S. Fauci recounts a career advising seven presidents. The chapter about Donald J. Trump is titled “He Loves Me, He Loves Me Not.”Three months into the coronavirus pandemic, Dr. Anthony S. Fauci was at home in northwest Washington when he answered his cellphone to President Donald J. Trump screaming at him in an expletive-laden rant. He had incurred the president’s wrath by remarking that the vaccines under development might not provide long-lasting immunity.That was the day, June 3, 2020, “that I first experienced the brunt of the president’s rage,” Dr. Fauci writes in his forthcoming autobiography.Dr. Fauci has long been circumspect in describing his feelings toward Mr. Trump. But in the book, “On Call: A Doctor’s Journey in Public Service,” he writes with candor about their relationship, which he describes as “complicated.”In a chapter entitled “He Loves Me, He Loves Me Not,” Dr. Fauci described how Mr. Trump repeatedly told him he “loved” him while at the same time excoriating him with tirades flecked with four-letter words.“The president was irate, saying that I could not keep doing this to him,” Dr. Fauci wrote. “He said he loved me, but the country was in trouble, and I was making it worse. He added that the stock market went up only 600 points in response to the positive Phase 1 vaccine news, and it should have gone up 1,000 points, and so I cost the country ‘one trillion dollars.’” (The president added an expletive.)“I have a pretty thick skin,” Dr. Fauci added, “but getting yelled at by the president of the United States, no matter how much he tells you that he loves you, is not fun.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      A Lesson From Covid on How to Destroy Public Trust

      by

      Big chunks of the history of the Covid pandemic were rewritten over the last month or so in a way that will have terrible consequences for many years to come.Under questioning by a congressional subcommittee, top officials from the National Institutes of Health, along with Dr. Anthony Fauci, acknowledged that some key parts of the public health guidance their agencies promoted during the first year of the Covid-19 pandemic were not backed up by solid science. What’s more, inconvenient information was kept from the public — suppressed, denied or disparaged as crackpot nonsense.Remember the rule that we should all stay at least six feet apart? “It sort of just appeared,” Fauci said during a preliminary interview for the subcommittee hearing, adding that he “was not aware of any studies” that supported it. Remember the insistence that the virus was primarily spread by droplets that quickly fell to the floor? During his recent public hearing, he acknowledged that to the contrary, the virus is airborne.As for the repeated assertion that Covid originated in a “wet market” in Wuhan, China, not in an infectious diseases laboratory there, N.I.H. officials were privately expressing alarm over that lab’s lax biosafety practices and risky research. In his public testimony, Fauci conceded that even now there “has not been definitive proof one way or the other” of Covid-19’s origins.Officials didn’t just spread these dubious ideas, they also demeaned anyone who dared to question them. “Dr. Fauci Throws Cold Water on Conspiracy Theory That Coronavirus Was Created in a Chinese Lab” was one typical headline. At the hearings, it emerged that Dr. David Morens, a senior N.I.H. figure, was deleting emails that discussed pandemic origins and using his personal account so as to avoid public oversight. “We’re all smart enough to know to never have smoking guns, and if we did we wouldn’t put them in emails and if we found them we’d delete them,” he wrote to the head of a nonprofit involved in research at the Wuhan lab.I wish I could say these were all just examples of the science evolving in real time, but they actually demonstrate obstinacy, arrogance and cowardice. Instead of circling the wagons, these officials should have been responsibly and transparently informing the public to the best of their knowledge and abilities.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      New Havana Syndrome Studies Find No Evidence of Brain Injuries

      by

      The findings from the National Institutes of Health are at odds with previous research that looked into the mysterious health incidents experienced by U.S. diplomats and spies.New studies by the National Institutes of Health failed to find evidence of brain injury in scans or blood markers of the diplomats and spies who suffered symptoms of Havana syndrome, bolstering the conclusions of U.S. intelligence agencies about the strange health incidents.Spy agencies have concluded that the debilitating symptoms associated with Havana syndrome, including dizziness and migraines, are not the work of a hostile foreign power. They have not identified a weapon or device that caused the injuries, and intelligence analysts now believe the symptoms are most likely explained by environmental factors, existing medical conditions or stress.The lead scientist on one of the two new studies said that while the study was not designed to find a cause, the findings were consistent with those determinations.The authors said the studies are at odds with findings from researchers at the University of Pennsylvania, who found differences in brain scans of people with Havana syndrome symptoms and a control groupDr. David Relman, a prominent scientist who has had access to the classified files involving the cases and representatives of people suffering from Havana syndrome, said the new studies were flawed. Many brain injuries are difficult to detect with scans or blood markers, he said. He added that the findings do not dispute that an external force, like a directed energy device, could have injured the current and former government workers.The studies were published in The Journal of the American Medical Association on Monday alongside an editorial by Dr. Relman that was critical of the findings.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Could Long Covid Be the Senate’s Bipartisan Cause?

      by

      Senator Roger Marshall’s voice was shaking with emotion as he made the case for speedy and focused research into long Covid. Marshall, the junior senator from Kansas, is a Republican and a medical doctor. But addressing the first-ever Senate hearing on long Covid last month, he wanted the audience to know that his interest wasn’t just professional and it definitely wasn’t just political. It was also personal.One of his loved ones, he explained, suffered from severe long Covid. “We’ve taken my loved one to dozens of doctors,” he said. “I’ve talked to 40, 50, 60, 80. I’ve read everything there is to read about long Covid, talked to other members of the Senate that have had long Covid. What are they doing? So I share your frustration.”It was personal for many in the audience, as well. Four years after the Covid pandemic began, leaving millions of people suffering from long-term health effects, the hearing had been announced with about a week’s notice — a scramble for people who were ill and, in many cases, in dire financial straits. But somehow the room was overflowing.Many in attendance told me they were worried that the political polarization around everything pandemic-related would thwart even belated progress on this important issue. I came away with a very different view.Bernie Sanders, the chair of the Senate Health, Education, Labor and Pensions Committee, kicked off the hearings by making an impassioned plea on behalf of the patients. He said the medical establishment had been too dismissive of their plight, and he conceded that Congress had not done nearly enough to help.But it was Marshall who spoke with precision about the scientific literature. He rattled off the leading theories about why some people with long Covid are debilitated and described specific symptoms in detail.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      In Trump’s Final Chapter, a Failure to Rise to the Covid-19 Moment

Biden Jr., but missed his chance to show that he could meet the defining challenge of his tenure.Credit…Doug Mills/The New York TimesMichael D. Shear, Maggie Haberman, Noah Weiland, Sharon LaFraniere and Dec. 31, 2020Updated 9:57 p.m. ETWASHINGTON — It was a warm summer Wednesday, Election Day was looming and President Trump was even angrier than usual at the relentless focus on the coronavirus pandemic.“You’re killing me! This whole thing is! We’ve got all the damn cases,” Mr. Trump yelled at Jared Kushner, his son-in-law and senior adviser, during a gathering of top aides in the Oval Office on Aug. 19. “I want to do what Mexico does. They don’t give you a test till you get to the emergency room and you’re vomiting.”Mexico’s record in fighting the virus was hardly one for the United States to emulate. But the president had long seen testing not as a vital way to track and contain the pandemic but as a mechanism for making him look bad by driving up the number of known cases.And on that day he was especially furious after being informed by Dr. Francis S. Collins, the head of the National Institutes of Health, that it would be days before the government could give emergency approval to the use of convalescent plasma as a treatment, something Mr. Trump was eager to promote as a personal victory going into the Republican National Convention the following week.“They’re Democrats! They’re against me!” he said, convinced that the government’s top doctors and scientists were conspiring to undermine him. “They want to wait!”Throughout late summer and fall, in the heat of a re-election campaign that he would go on to lose, and in the face of mounting evidence of a surge in infections and deaths far worse than in the spring, Mr. Trump’s management of the crisis — unsteady, unscientific and colored by politics all year — was in effect reduced to a single question: What would it mean for him?The result, according to interviews with more than two dozen current and former administration officials and others in contact with the White House, was a lose-lose situation. Mr. Trump not only ended up soundly defeated by Joseph R. Biden Jr., but missed his chance to show that he could rise to the moment in the final chapter of his presidency and meet the defining challenge of his tenure.Efforts by his aides to persuade him to promote mask wearing, among the simplest and most effective ways to curb the spread of the disease, were derailed by his conviction that his political base would rebel against anything that would smack of limiting their personal freedom. Even his own campaign’s polling data to the contrary could not sway him.His explicit demand for a vaccine by Election Day — a push that came to a head in a contentious Oval Office meeting with top health aides in late September — became a misguided substitute for warning the nation that failure to adhere to social distancing and other mitigation efforts would contribute to a slow-rolling disaster this winter.His concern? That the man he called “Sleepy Joe” Biden, who was leading him in the polls, would get credit for a vaccine, not him.The government’s public health experts were all but silenced by the arrival in August of Dr. Scott W. Atlas, the Stanford professor of neuroradiology recruited after appearances on Fox News.With Dr. Deborah L. Birx, the coordinator of the White House virus task force, losing influence and often on the road, Dr. Atlas became the sole doctor Mr. Trump listened to. His theories, some of which scientists viewed as bordering on the crackpot, were exactly what the president wanted to hear: The virus is overblown, the number of deaths is exaggerated, testing is overrated, lockdowns do more harm than good.The president has long seen testing not as a vital way to track and contain the pandemic but as a mechanism for making him look bad by driving up the number of known cases.Credit…William DeShazer for The New York TimesAs the gap between politics and science grew, the infighting that Mr. Trump had allowed to plague the administration’s response from the beginning only intensified. Threats of firings worsened the leadership vacuum as key figures undercut each other and distanced themselves from responsibility.The administration had some positive stories to tell. Mr. Trump’s vaccine development program, Operation Warp Speed, had helped drive the pharmaceutical industry’s remarkably fast progress in developing several promising approaches. By the end of the year, two highly effective vaccines would be approved for emergency use, providing hope for 2021.The White House rejected any suggestions that the president’s response had fallen short, saying he had worked to provide adequate testing, protective equipment and hospital capacity and that the vaccine development program had succeeded in record time.“President Trump has led the largest mobilization of the public and private sectors since WWII to defeat Covid-19 and save lives,” said Brian Morgenstern, a White House spokesman.But Mr. Trump’s unwillingness to put aside his political self-centeredness as Americans died by the thousands each day or to embrace the steps necessary to deal with the crisis remains confounding even to some administration officials. “Making masks a culture war issue was the dumbest thing imaginable,” one former senior adviser said.His own bout with Covid-19 in early October left him extremely ill and dependent on care and drugs not available to most Americans, including a still-experimental monoclonal antibody treatment, and he saw firsthand how the disease coursed through the White House and some of his close allies.Yet his instinct was to treat that experience not as a learning moment or an opportunity for empathy, but as a chance to portray himself as a Superman who had vanquished the disease. His own experience to the contrary, he assured a crowd at the White House just a week after his hospitalization, “It’s going to disappear; it is disappearing.”Weeks after his own recovery, he would still complain about the nation’s preoccupation with the pandemic.“All you hear is Covid, Covid, Covid, Covid, Covid, Covid, Covid, Covid, Covid, Covid, Covid,” Mr. Trump said at one campaign stop, uttering the word 11 times.In the end he could not escape it.Supporters of Mr. Trump outside Walter Reed National Military Medical Center, where he was treated for the coronavirus, in October. He largely rejected aides’ efforts to use his bout with the illness to demonstrate a new compassion.Credit…Oliver Contreras for The New York Times‘The Base Will Revolt’By late July, new cases were at record highs, defying Mr. Trump’s predictions through the spring that the virus was under control, and deaths were spiking to alarming levels. Herman Cain, a 2012 Republican presidential candidate, died from the coronavirus; the previous month he had attended a Trump rally without a mask.With the pandemic defining the campaign despite Mr. Trump’s efforts to make it about law and order, Tony Fabrizio, the president’s main pollster, came to the Oval Office for a meeting in the middle of the summer prepared to make a surprising case: that mask wearing was acceptable even among Mr. Trump’s supporters.Arrayed in front of the Resolute Desk, Mr. Trump’s advisers listened as Mr. Fabrizio presented the numbers. According to his research, some of which was reported by The Washington Post, voters believed the pandemic was bad and getting worse, they were more concerned about getting sick than about the virus’s effects on their personal financial situation, the president’s approval rating on handling the pandemic had hit new lows and a little more than half the country did not think he was taking the situation seriously.But what set off debate that day was Mr. Fabrizio’s finding that more than 70 percent of voters in the states being targeted by the campaign supported mandatory mask wearing in public, at least indoors, including a majority of Republicans.Mr. Kushner, who along with Hope Hicks, another top adviser, had been trying for months to convince Mr. Trump that masks could be portrayed as the key to regaining freedom to go safely to a restaurant or a sporting event, called embracing mask-wearing a “no-brainer.”Mr. Kushner had some reason for optimism. Mr. Trump had agreed to wear one not long before for a visit to Walter Reed National Military Medical Center, after finding one he believed he looked good in: dark blue, with a presidential seal.But Mark Meadows, the White House chief of staff — backed up by other aides including Stephen Miller — said the politics for Mr. Trump would be devastating.“The base will revolt,” Mr. Meadows said, adding that he was not sure Mr. Trump could legally make it happen in any case.The president removed his mask upon arriving at the White House on Oct. 5, after being hospitalized with Covid-19. He was rarely seen wearing one again.Credit…Anna Moneymaker for The New York TimesThat was all Mr. Trump needed to hear. “I’m not doing a mask mandate,” he concluded.Aside from when he was sick, he was rarely seen in a mask again.The president had other opportunities to show leadership rather than put his political fortunes first..css-fk3g7a{font-family:nyt-franklin,helvetica,arial,sans-serif;font-weight:700;font-size:0.875rem;line-height:1.125rem;color:#121212 !important;}@media (min-width:740px){.css-fk3g7a{font-size:0.9375rem;line-height:1.25rem;}}.css-1sjr751{-webkit-text-decoration:none;text-decoration:none;}.css-1sjr751 a:hover{border-bottom:1px solid #dcdcdc;}.css-rqynmc{font-family:nyt-franklin,helvetica,arial,sans-serif;font-size:0.9375rem;line-height:1.25rem;color:#333;margin-bottom:0.78125rem;}@media (min-width:740px){.css-rqynmc{font-size:1.0625rem;line-height:1.5rem;margin-bottom:0.9375rem;}}.css-rqynmc strong{font-weight:600;}.css-rqynmc em{font-style:italic;}.css-zs9392{margin:10px auto 5px;font-family:nyt-franklin,helvetica,arial,sans-serif;font-weight:700;font-size:1.125rem;line-height:1.3125rem;color:#121212;}@media (min-width:740px){.css-zs9392{font-size:1.25rem;line-height:1.4375rem;}}#NYT_BELOW_MAIN_CONTENT_REGION .css-zs9392{font-family:nyt-cheltenham,georgia,’times new roman’,times,serif;font-weight:700;font-size:1.375rem;line-height:1.75rem;margin-bottom:20px;}@media (min-width:740px){#NYT_BELOW_MAIN_CONTENT_REGION .css-zs9392{font-size:1.5rem;line-height:1.875rem;}}.css-121grtr{margin:0 auto 10px;}.css-16ed7iq{width:100%;display:-webkit-box;display:-webkit-flex;display:-ms-flexbox;display:flex;-webkit-align-items:center;-webkit-box-align:center;-ms-flex-align:center;align-items:center;-webkit-box-pack:center;-webkit-justify-content:center;-ms-flex-pack:center;justify-content:center;padding:10px 0;background-color:white;}.css-pmm6ed{display:-webkit-box;display:-webkit-flex;display:-ms-flexbox;display:flex;-webkit-align-items:center;-webkit-box-align:center;-ms-flex-align:center;align-items:center;}.css-pmm6ed > :not(:first-child){margin-left:5px;}.css-5gimkt{font-family:nyt-franklin,helvetica,arial,sans-serif;font-size:0.8125rem;font-weight:700;-webkit-letter-spacing:0.03em;-moz-letter-spacing:0.03em;-ms-letter-spacing:0.03em;letter-spacing:0.03em;text-transform:uppercase;color:#333;}.css-5gimkt:after{content:’Collapse’;}.css-rdoyk0{-webkit-transition:all 0.5s ease;transition:all 0.5s ease;-webkit-transform:rotate(180deg);-ms-transform:rotate(180deg);transform:rotate(180deg);}.css-eb027h{max-height:5000px;-webkit-transition:max-height 0.5s ease;transition:max-height 0.5s ease;}.css-6mllg9{-webkit-transition:all 0.5s ease;transition:all 0.5s ease;position:relative;opacity:0;}.css-6mllg9:before{content:”;background-image:linear-gradient(180deg,transparent,#ffffff);background-image:-webkit-linear-gradient(270deg,rgba(255,255,255,0),#ffffff);height:80px;width:100%;position:absolute;bottom:0px;pointer-events:none;}#masthead-bar-one{display:none;}#masthead-bar-one{display:none;}.css-qmg6q8{background-color:white;margin:1.5rem auto 1.9rem;max-width:600px;}#NYT_BELOW_MAIN_CONTENT_REGION .css-qmg6q8{padding:0;width:calc(100% – 40px);max-width:600px;margin-right:auto;margin-left:auto;}.css-qmg6q8 strong{font-weight:700;}.css-qmg6q8 em{font-style:italic;}@media (min-width:740px){.css-qmg6q8{margin:40px auto;}}.css-qmg6q8:focus{outline:1px solid #e2e2e2;}.css-qmg6q8 a{color:#326891;-webkit-text-decoration:none;text-decoration:none;border-bottom:1px solid #ccd9e3;}.css-qmg6q8 a:visited{color:#333;-webkit-text-decoration:none;text-decoration:none;border-bottom:1px solid #ddd;}.css-qmg6q8 a:hover{border-bottom:none;}.css-qmg6q8[data-truncated] .css-rdoyk0{-webkit-transform:rotate(0deg);-ms-transform:rotate(0deg);transform:rotate(0deg);}.css-qmg6q8[data-truncated] .css-eb027h{max-height:300px;overflow:hidden;-webkit-transition:none;transition:none;}.css-qmg6q8[data-truncated] .css-5gimkt:after{content:’See more’;}.css-qmg6q8[data-truncated] .css-6mllg9{opacity:1;}.css-11uwurf{border:1px solid #e2e2e2;padding:15px;border-radius:0;margin:0 auto;overflow:hidden;}@media (min-width:600px){.css-11uwurf{padding:20px;}}#NYT_BELOW_MAIN_CONTENT_REGION .css-11uwurf{border-top:1px solid #121212;border-bottom:none;}Covid-19 Vaccines ›Answers to Your Vaccine QuestionsWith distribution of a coronavirus vaccine beginning in the U.S., here are answers to some questions you may be wondering about:If I live in the U.S., when can I get the vaccine? While the exact order of vaccine recipients may vary by state, most will likely put medical workers and residents of long-term care facilities first. If you want to understand how this decision is getting made, this article will help.When can I return to normal life after being vaccinated? Life will return to normal only when society as a whole gains enough protection against the coronavirus. Once countries authorize a vaccine, they’ll only be able to vaccinate a few percent of their citizens at most in the first couple months. The unvaccinated majority will still remain vulnerable to getting infected. A growing number of coronavirus vaccines are showing robust protection against becoming sick. But it’s also possible for people to spread the virus without even knowing they’re infected because they experience only mild symptoms or none at all. Scientists don’t yet know if the vaccines also block the transmission of the coronavirus. So for the time being, even vaccinated people will need to wear masks, avoid indoor crowds, and so on. Once enough people get vaccinated, it will become very difficult for the coronavirus to find vulnerable people to infect. Depending on how quickly we as a society achieve that goal, life might start approaching something like normal by the fall 2021.If I’ve been vaccinated, do I still need to wear a mask? Yes, but not forever. Here’s why. The coronavirus vaccines are injected deep into the muscles and stimulate the immune system to produce antibodies. This appears to be enough protection to keep the vaccinated person from getting ill. But what’s not clear is whether it’s possible for the virus to bloom in the nose — and be sneezed or breathed out to infect others — even as antibodies elsewhere in the body have mobilized to prevent the vaccinated person from getting sick. The vaccine clinical trials were designed to determine whether vaccinated people are protected from illness — not to find out whether they could still spread the coronavirus. Based on studies of flu vaccine and even patients infected with Covid-19, researchers have reason to be hopeful that vaccinated people won’t spread the virus, but more research is needed. In the meantime, everyone — even vaccinated people — will need to think of themselves as possible silent spreaders and keep wearing a mask. Read more here.Will it hurt? What are the side effects? The Pfizer and BioNTech vaccine is delivered as a shot in the arm, like other typical vaccines. The injection into your arm won’t feel different than any other vaccine, but the rate of short-lived side effects does appear higher than a flu shot. Tens of thousands of people have already received the vaccines, and none of them have reported any serious health problems. The side effects, which can resemble the symptoms of Covid-19, last about a day and appear more likely after the second dose. Early reports from vaccine trials suggest some people might need to take a day off from work because they feel lousy after receiving the second dose. In the Pfizer study, about half developed fatigue. Other side effects occurred in at least 25 to 33 percent of patients, sometimes more, including headaches, chills and muscle pain. While these experiences aren’t pleasant, they are a good sign that your own immune system is mounting a potent response to the vaccine that will provide long-lasting immunity.Will mRNA vaccines change my genes? No. The vaccines from Moderna and Pfizer use a genetic molecule to prime the immune system. That molecule, known as mRNA, is eventually destroyed by the body. The mRNA is packaged in an oily bubble that can fuse to a cell, allowing the molecule to slip in. The cell uses the mRNA to make proteins from the coronavirus, which can stimulate the immune system. At any moment, each of our cells may contain hundreds of thousands of mRNA molecules, which they produce in order to make proteins of their own. Once those proteins are made, our cells then shred the mRNA with special enzymes. The mRNA molecules our cells make can only survive a matter of minutes. The mRNA in vaccines is engineered to withstand the cell’s enzymes a bit longer, so that the cells can make extra virus proteins and prompt a stronger immune response. But the mRNA can only last for a few days at most before they are destroyed.After he recovered from his bout with the virus, some of his top aides, including Mr. Kushner and Jason Miller, a senior campaign strategist, thought the illness offered an opportunity to demonstrate the kind of compassion and resolve about the pandemic’s toll that Mr. Trump had so far failed to show.When Mr. Trump returned from the hospital, his communications aides, with the help of Ivanka Trump, his daughter, urged him to deliver a national address in which he would say: “I had it. It was tough, it kicked my ass, but we’re going to get through it.”He refused, choosing instead to address a boisterous campaign rally for himself from the balcony of the White House overlooking the South Lawn.Mr. Trump never came around to the idea that he had a responsibility to be a role model, much less that his leadership role might require him to publicly acknowledge hard truths about the virus — or even to stop insisting that the issue was not a rampaging pandemic but too much testing.Alex M. Azar II, the health and human services secretary, briefed the president this fall on a Japanese study documenting the effectiveness of face masks, telling him: “We have the proof. They work.” But the president resisted, criticizing Mr. Kushner for pushing them and again blaming too much testing — an area Mr. Kushner had been helping to oversee — for his problems.“I’m going to lose,” Mr. Trump told Mr. Kushner during debate preparations. “And it’s going to be your fault, because of the testing.”Mr. Morgenstern, the White House spokesman, said that exchange between the president and Mr. Kushner “never happened.”Mr. Azar, who was sometimes one of the few people wearing a mask at White House events, privately bemoaned what he called a political, anti-mask culture set by Mr. Trump. At White House Christmas parties, Mr. Azar asked maskless guests to back away from him.Dr. Stephen M. Hahn, center, the commissioner of the Food and Drug Administration, Dr. Deborah L.

The idea was to break down barriers between disparate agencies, assemble public health expertise and encourage quick and coordinated decision-making.It did not work out like that, and by fall the consequences were clear.Mr. Trump had always tolerated if not encouraged clashes among subordinates, a tendency that in this case led only to policy paralysis, confusion about who was in charge and a lack of a clear, consistent message about how to reduce the risks from the pandemic.Keeping decision-making power close to him was another Trump trait, but in this case it also elevated the myriad choices facing the administration to the presidential level, bogging the process down in infighting, raising the political stakes and encouraging aides to jockey for favor with Mr. Trump.The result at times was a systemwide failure that extended well beyond the president.“What we needed was a coordinated response that involved contributions from multiple agencies,” said Dr. Scott Gottlieb, who was commissioner of the Food and Drug Administration for the first two years of the Trump administration.“Someone needed to pull that all together early,” he said. “It wasn’t the job of the White House, either. This needed to happen closer to the agencies. That didn’t happen on testing, or on a whole lot of other things.”The relationship between Mr. Azar and Dr. Stephen M. Hahn, the commissioner of the Food and Drug Administration, grew increasingly tense; by early November, they were communicating only by text and in meetings.Dr. Birx had lost the clout she enjoyed early on in the crisis and spent much of the summer and fall on the road counseling governors and state health officials.Mr. Meadows was at odds with almost everyone as he sought to impose the president’s will on scientists and public health professionals. In conversations with top health officials, Mr. Meadows would rail against regulatory “bureaucrats” he thought were more interested in process than outcome.Some of the doctors on the task force, including Dr. Anthony S. Fauci and Dr. Robert R. Redfield, were reluctant to show up in person at the White House, worried that the disdain there for mask wearing and social distancing would leave them at risk of infection.Vice President Mike Pence was nominally in charge of the task force but was so cautious about getting crosswise with Mr. Trump as they battled for re-election that, in public at least, he became nearly invisible.The debates inside the White House increasingly revolved around Dr. Atlas, who had no formal training in infectious diseases but whose views — which Mr. Trump saw him deliver on Fox News — appealed to the president’s belief that the crisis was overblown.Dr. Scott W. Atlas, the Stanford professor of neuroradiology recruited after appearances on Fox News, became the sole doctor Mr. Trump listened to.Credit…Anna Moneymaker for The New York TimesHis arrival at 1600 Pennsylvania Avenue was itself something of a mystery. Some aides said he was discovered by Kayleigh McEnany, the White House press secretary. Others said John McEntee, the president’s personnel chief, had been Googling for a Trump-friendly doctor who would be loyal.Marc Short, Mr. Pence’s chief of staff, opposed hiring Dr. Atlas. But once the president and his team brought him in, Mr. Short insisted that Dr. Atlas have a seat at the task force table, hoping to avoid having him become yet another internal — and destructive — critic.Once inside, Dr. Atlas used the perch of a West Wing office to shape the response. During a meeting in early fall, Dr. Atlas asserted that college students were at no risk from the virus. We should let them go back to school, he said. It’s not a problem.Dr. Birx exploded. What aspect of the fact that you can be asymptomatic and still spread it do you not understand? she demanded. You might not die, but you can give it to somebody who can die from it. She was livid.“Your strategy is literally going to cost us lives,” she yelled at Dr. Atlas. She attacked Dr. Atlas’s ideas in daily emails she sent to senior officials. And she was mindful of a pact she had made with Dr. Hahn, Dr. Fauci and Dr. Redfield even before Dr. Atlas came on board: They would stick together if one of them was fired for doing what they considered the right thing.Health officials often had a hard time finding an audience in the upper reaches of the West Wing. In a mid-November task force meeting, they issued a dire warning to Mr. Meadows about the looming surge in cases set to devastate the country. Mr. Meadows demanded data to back up their claim.One outcome of the meeting was a Nov. 19 news conference on the virus’s dire threat, the first in many weeks. But while Mr. Pence, who led the briefing, often urged Americans to “do their part” to slow the spread of the virus, he never directly challenged Mr. Trump’s hesitancy on masks and social distancing. At the briefing, he said that “decision making at the local level” was key, continuing a long pattern of the administration seeking to push responsibility to the states.Mr. Azar had been cut out of key decision-making as early as February, when Mr. Pence took over the task force. Mr. Azar would complain to his associates that Mr. Pence’s staff and task force members went around him to issue orders to his subordinates.On tenterhooks about his job status, Mr. Azar found an opening that offered a kind of redemption, steering his attention through the summer and fall to Operation Warp Speed, the government’s effort to support rapid development of a vaccine, lavishing praise on Mr. Trump and crediting him for nearly every advance.Behind the scenes, Mr. Azar portrayed Dr. Hahn to the White House as a flailing manager — a complaint he also voiced about Dr. Redfield. In late September, he told the White House he was willing to fire Dr. Hahn, according to officials familiar with the offer.For their part, Dr. Hahn, Dr. Redfield, Dr. Birx and other senior health officials saw Mr. Azar as crushing the morale of the agencies he oversaw as he sought to escape blame for a worsening crisis and to strengthen his own image publicly and with the White House.Health officials on the task force several times took their complaints about Mr. Azar to Mr. Pence’s office, hoping for an intervention.Caitlin B. Oakley, a spokeswoman for Mr. Azar, said he had “always stood up for balanced, scientific, public health information and insisted that science and data drive the decisions.”Once eager to visit the White House, Dr. Hahn became disillusioned with what he saw as its efforts to politicize the work of the Food and Drug Administration, and he eventually shied away from task force meetings, fearing his statements there would leak.If there was a bureaucratic winner in this West Wing cage match, it was Dr. Atlas.He told Mr. Trump that the right way to think about the virus was how much “excess mortality” there was above what would have been expected without a pandemic.Mr. Trump seized on the idea, often telling aides that the real number of dead was no more than 10,000 people.As of Thursday, 342,577 Americans had died from the pandemic.Two coronavirus vaccines arrived at sites across the country this month. Mr. Trump was furious that a successful vaccine was not announced until after the election.Credit…Bryan Anselm for The New York TimesTrump vs. Vaccine RegulatorsIn an Oval Office meeting with senior health officials on Sept. 24, the president made explicit what he had long implied: He wanted a vaccine before the election, according to three people who witnessed his demand.Pfizer’s chief executive had been encouraging the belief that the company could deliver initial results by late October. But Mr. Trump’s aides tried in vain to make clear that they could not completely control the timing.Dr. Fauci and Dr. Hahn reminded West Wing officials that a company’s vaccine trial results were a “black box,” impossible to see until an independent monitoring board revealed them. A vaccine that did not go through the usual, rigorous government approval process would be a “Pyrrhic victory,” Mr. Azar told them. It would be a shot no one would take.Dr. Moncef Slaoui, the scientific leader of Operation Warp Speed, said the president never asked him to deliver a vaccine on a specific timetable. But he said Mr. Trump sometimes complained in meetings that “it was not going to happen before the election and it will be ‘Sleepy Joe’” who would ultimately get credit.In late October, science and regulations worked against Mr. Trump’s waning hopes for pre-Election Day good news. At the F.D.A., scientists had refined the standards for authorizing a vaccine for emergency use. And at Pfizer, executives realized that the agency was unlikely to authorize its vaccine on the basis of so few Covid-19 cases among its clinical trial volunteers.They decided to wait for more data, a delay of up to a week.When Pfizer announced on Nov. 9 — two days after Mr. Biden clinched his victory — that its vaccine was a stunning success, Mr. Trump was furious. He lashed out at the company, Dr. Hahn and the F.D.A., accusing “deep state regulators” of conspiring with Pfizer to slow approval until after the election.The president’s frustration with the pace of regulatory action would continue into December, as the F.D.A. went through a time-consuming process of evaluating Pfizer’s data and then that of a second vaccine maker, Moderna.On Dec. 11, Mr. Meadows exploded during a morning call with Dr. Hahn and Dr. Peter Marks, the agency’s top vaccine regulator. He accused Dr. Hahn of mismanagement and suggested he resign, then slammed down the phone. That night, the F.D.A. authorized the Pfizer vaccine.In the weeks that followed, Mr. Pence, Mr. Azar, Dr. Fauci and other health officials rolled up their sleeves to be vaccinated for the cameras.Mr. Trump, who after contracting Covid-19 had declared himself immune, has not announced plans to be vaccinated.Michael D.
