CDC shifts pandemic goals away from reaching herd immunity

EXCERPT: . . . “Thinking that we’ll be able to achieve some kind of threshold where there’ll be no more transmission of infections may not be possible,” Jones acknowledged last week to members of a panel that advises the CDC on vaccines.
Vaccines have been quite effective at preventing cases of COVID-19 that lead to severe illness and death, but none has proved reliable at blocking transmission of the virus, Jones noted. Recent evidence has also made clear that the immunity provided by vaccines can wane in a matter of months.
The result is that even if vaccination were universal, the coronavirus would probably continue to spread. “We would discourage” thinking in terms of “a strict goal,” he said... (MORE - missing details)

EXCERPT: . . . This story isn’t about a medical mystery. The pandemic was a near-perfect mass hair-loss event, and anyone with the most basic understanding of why people lose their hair could have spotted it from a mile away. The actual mystery, instead, is why almost no one has that understanding in the first place.
Hair loss, I eventually learned from my diligent Googling, can be temporary or permanent, and it has many causes—heredity, chronic illness, nutritional deficiency, daily too-tight ponytails. But one type of loss is responsible for the pandemic hair-loss spike: telogen effluvium. TE, as it’s often called, is sudden and can be dramatic. It’s caused by the ordinary traumas of human existence in all of their hideous variety. Any kind of intense physical or emotional stress can push as much as 70 percent of your hair into the “telogen” phase of its growth cycle, which halts those strands’ growth and disconnects them from their blood supply in order to conserve resources for more essential bodily processes. That, in time, knocks them straight off your head.
The pandemic has manufactured trauma at an astonishing clip. Many cases of TE have been caused by COVID-19 infection itself, according to Esther Freeman, a dermatologist and an epidemiologist at Harvard Medical School and the principal investigator for the COVID-19 Dermatology Registry, which collects reports of COVID-19’s effects on skin, nails, and hair. That doesn’t necessarily have anything to do with something unique about the disease, she told me—any illness that comes with a high fever can cause a round of TE, including common illnesses such as the flu. Among the millions of Americans who have been infected by the coronavirus, hair loss has been a common consequence, she said, both for patients whose symptoms resolve in a couple of weeks and for those who develop long COVID. Researchers do not yet know exactly how prevalent hair loss is among COVID-19 patients, but one study found that among those hospitalized, 22 percent were still dealing with hair loss months later.
COVID-19 infections are only part of the picture. Throughout the pandemic, millions more Americans have suffered devastating emotional stress even if they’ve never gotten sick: watching a loved one die, losing a job, going to work in life-threatening conditions, bearing the brunt of violent political unrest. Feelings can have concrete, involuntary physical manifestations, and these traumas are exactly the kinds that leave people staring in horror at the handfuls of hair they gather while lathering up in the shower.
All of these factors have led to what Jeff Donovan, a hair-loss dermatologist in Whistler, British Columbia, described to me as a “mountain” of new hair-loss patients since the pandemic began... (MORE - missing details)
