It’s year-end-list season. Usually, the Vox science team has some fun and compiles a year-end list of bad ideas in health and science that ought to die with the end of the year. In the past, we’ve targeted homeopathic medicine, declared it was time to end the relevance of the fatally flawed Stanford Prison Experiment, and dispelled myths about climate change. This year, though, we have only one target for intellectual demolition.

With the end of 2020, let’s leave behind the idea of using herd immunity acquired through natural infections as a means of combating the Covid-19 pandemic. That’s a lot of words to describe a simple, terrible idea: that we could end the pandemic sooner if more people — particularly young, less-at-risk people — get infected with the coronavirus and develop immunity as a result.

As a response to a pandemic, the idea is unprecedented. “Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic,” World Health Organization Director-General Tedros Adhanom Ghebreyesus said in October. “It is scientifically and ethically problematic.”

And yet it held sway — at the White House, in particular.

Former White House adviser Scott Atlas (who is a neuroradiologist, not an epidemiologist) was particularly vocal about pursuing more infections. “When younger, healthier people get infected, that’s a good thing,” Atlas said in a July interview with San Diego news station KUSI-TV. “The goal is not to eliminate all cases. That’s not rational, it’s not necessary if we just protect the people who are going to have serious complications.”

Let’s be clear, it’s not a “good thing” when young people get sick. For one, some of these young people may die, more may get severely ill, and a not-yet-understood proportion of them could suffer long-term consequences. The more people infected, the more chances for rare, horrible things to happen, like a 4-month-old developing brain swelling after testing positive for Covid-19. For that reason, among others, attempting to keep infections to only young or lower-risk people is a foolhardy game to play. [Continue reading…]
