For many fully vaccinated Americans, the Delta surge spoiled what should’ve been a glorious summer. Those who had cast their masks aside months ago were asked to dust them off. Many are still taking no chances. Some have even returned to all the same precautions they took before getting their shots, including avoiding the company of other fully vaccinated people.

Among this last group, a common refrain I’ve heard to justify their renewed vigilance is that “vaccinated people are just as likely to spread the coronavirus.”

This misunderstanding, born out of confusing statements from public-health authorities and misleading media headlines, is a shame. It is resulting in unnecessary fear among vaccinated people, all the while undermining the public’s understanding of the importance—and effectiveness—of getting vaccinated.

Last year, John Eastman, whom CNN describes as an attorney working with Donald Trump’s legal team, wrote a preposterous memo outlining how then–Vice President Mike Pence could overturn the 2020 election by fiat or, failing that, throw the election to the House of Representatives, where Republicans could install Trump in office despite his loss to Joe Biden. The document, which was first reported by the Washington Post journalists Bob Woodward and Robert Costa in their new book, is a step-by-step plan to overthrow the government of the United States through a preposterous interpretation of legal procedure.

Pence apparently took the idea seriously—so seriously, in fact, that, according to Woodward and Costa, former Vice President Dan Quayle had to talk him out of it. Prior to November, the possibility of Trump attempting a coup was seen as the deranged fever dream of crazed liberals. But as it turns out, Trump and his advisers had devised explicit plans for reversing Trump’s loss. Republican leaders deliberately stoked election conspiracy theories they knew to be false, in order to lay a political pretext for invalidating the results. Now, more than 10 months after the election, the country knows of at least five ways in which Trump attempted to retain power despite his defeat.

Political courage is a fascinating phenomenon, particularly at moments when it is largely absent. Which is why I’m so interested in the imperiled career of Representative Adam Kinzinger, the Illinois Republican who has described Donald Trump’s demagogy for what it is—a danger to the republic—and who possesses spine enough to excoriate members of his own party for succumbing to Trump’s imbecilic authoritarianism.

As Anne Applebaum described so well in her Atlantic cover story last year, “We all feel the urge to conform; it is the most normal of human desires.” Her essay, “History Will Judge the Complicit,” made the argument that collaboration, and not dissent, is the default posture of frightened humans, including and especially careerist politicians. Dissent can often lead to social and political death (and sometimes, physical death), and, as we’ve learned in the months following the insurrection of January 6, most Republicans would sooner cast people like Kinzinger into the wilderness than risk ostracism.

On Saturday morning, I finally rolled up my sleeve for the vaccine I’d been waiting for all summer: my annual flu shot, a technological marvel that I opt to receive every fall.

During non-pandemic times, the flu vaccine is a hot autumn commodity that holds a coveted place in the public-health spotlight. As of late, though, the shot’s been eclipsed by the prominence of its COVID-blocking cousins, fueled by debates over boosters and mandates. It’s also been a while since we’ve had to tussle with the flu directly. Thanks to the infection-prevention measures the world took to fight SARS-CoV-2 when the pandemic began, many other respiratory viruses vanished. Last winter, we essentially had “no flu season at all,” Florian Krammer, a virologist at Mount Sinai’s Icahn School of Medicine, told me. The human attention span is short; the flu’s brief sabbatical might have purged it from our minds at an inopportune time.

American wealth and power usually have a certain look: glass-walled penthouse apartments in glittering urban skyscrapers, sprawling country mansions, ivy-covered prep schools, vacation homes in the Hamptons. These are the outward symbols of an entrenched oligarchy, the political-economic ruling class portrayed by the media that entertains us and the conspiracy theories that animate the darker corners of the American imagination.

The reality of American wealth and power is more banal. The conspicuously consuming celebrities and jet-setting cosmopolitans of popular imagination exist, but they are far outnumbered by a less exalted and less discussed elite group, one that sits at the pinnacle of the local hierarchies that govern daily life for tens of millions of people. Donald Trump grasped this group’s existence and its importance, acting, as he often does, on unthinking but effective instinct. When he crowed about his “beautiful boaters,” lauding the flotillas of supporters trailing MAGA flags from their watercraft in his honor, or addressed his devoted followers among a rioting January 6 crowd that included people who had flown to the event on private jets, he knew what he was doing. Trump was courting the support of the American gentry, the salt-of-the-earth millionaires who see themselves as local leaders in business and politics, the unappreciated backbone of a once-great nation.

For nearly two years now, Americans have lived with SARS-CoV-2. We know it better than we once did. We know that it can set off both acute and chronic illness, that it spreads best indoors, that masks help block it, that our vaccines are powerful against it. We know that we can live with it—that we’re going to have to live with it—but that it can and will exact a heavy toll.

Still, this virus has the capacity to surprise us, especially if we’re not paying attention. It is changing all the time, a tweak to the genetic code here and there; sometimes, those tweaks add up to new danger. In a matter of weeks, the Delta variant upended the relative peace of America’s early summer and ushered in a new set of calculations about risk, masking, and testing. The pandemic’s endgame shifted.

“It’s not true that no one needs you anymore.”

These words came from an elderly woman sitting behind me on a late-night flight from Los Angeles to Washington, D.C. The plane was dark and quiet. A man I assumed to be her husband murmured almost inaudibly in response, something to the effect of “I wish I was dead.”

Again, the woman: “Oh, stop saying that.”

I didn’t mean to eavesdrop, but couldn’t help it. I listened with morbid fascination, forming an image of the man in my head as they talked. I imagined someone who had worked hard all his life in relative obscurity, someone with unfulfilled dreams—perhaps of the degree he never attained, the career he never pursued, the company he never started.

Boghuma Kabisen Titanji was just 8 years old when the hyper-contagious virus swept through her classroom. Days later, she started to feel feverish, and developed a sparse, rosy rash. Three years after being fully dosed with the measles vaccine, one of the most durably effective immunizations in our roster, Titanji fell ill with the very pathogen her shots were designed to prevent.

Her parents rushed her to a pediatrician, worried that her first inoculations had failed to take. But the doctor allayed their fears: “It happens. She’ll be fine.” And she was. Her fever and rash cleared up in just a couple of days; she never sickened anyone else in her family. It was, says Titanji, now an infectious-disease physician and a researcher at Emory University, a textbook case of “modified” measles, a rare post-vaccination illness so mild and unthreatening that it doesn’t even deserve the full measles name.

After a long and tense meeting today, an FDA committee unanimously recommended that the agency authorize third shots of the Pfizer COVID-19 vaccine for Americans who are over 65 or at high risk of severe COVID. The vote came after the panel voted overwhelmingly against the original question up for its consideration: authorizing boosters for everyone over 16. If the FDA follows the committee’s recommendation (as is expected), a CDC committee will help refine those guidelines next week, clarifying which groups qualify as “high risk.”

Even as we await these final decisions, the nation’s summer wave of COVID infections seems like it’s beginning to pass. Cases and hospitalizations are trending slightly downward. Now that we have more clarity about whether (and which) Americans need booster shots—and given that so many people are already getting boosters, eligibility be damned—more questions loom: When, exactly, should those people get those shots? Is it better to load up on extra antibodies as soon as possible, or should people wait until COVID rates start to rise again?

Conspiracy theorists who discount the safety and efficacy of COVID-19 vaccines and other public-health mandates are often portrayed in the media as right-wing. That’s for good reason: a not-insignificant number of the most vocal conspiracists tie their ideology firmly to President Donald Trump and the right-wing MAGA movement he inspired. Videos of angry red-state demonstrators pushing back against school boards and other local authorities in public hearings, and repeating outlandish, baseless misinformation, have made the rounds in traditional media.

But in the hills of western Massachusetts and in neighboring regions of upstate New York, a traditionally left-leaning area, these theories also hold purchase. I grew up in the region and started my journalistic career there. I’ve been arguing with residents, many of whom are close friends, about vaccines for more than a decade. But despite my efforts, and the efforts of many others, a stubborn resistance to reality has set in here, and only deepened since the pandemic began. Late last month, Do We Need This?, a group of anti-vaxxers and vaccine-mandate opponents, held a “festival” in the region to raise money for their cause, suggesting a $20 donation for entry. They shared the proceeds with other national vaccine-skeptic groups, including NY Stands Up!, the Informed Consent Action Network, and Robert Kennedy Jr.’s Children’s Health Defense.
