"At least 200 million people worldwide have struggled with long COVID: a slew
of symptoms that can persist for months or even years after an infection with
SARS-CoV-2, the virus that causes COVID. But research suggests that that number
would likely be much higher if not for vaccines.
A growing consensus is emerging that receiving multiple doses of the COVID
vaccine before an initial infection can dramatically reduce the risk of
long-term symptoms. Although the studies disagree on the exact amount of
protection, they show a clear trend: the more shots in your arm before your
first bout with COVID, the less likely you are to get long COVID. One
meta-analysis of 24 studies published in October, for example, found that
people who’d had three doses of the COVID vaccine were 68.7 percent less likely
to develop long COVID compared with those who were unvaccinated. “This is
really impressive,” says Alexandre Marra, a medical researcher at the Albert
Einstein Israelite Hospital in Brazil and the lead author of the study.
“Booster doses make a difference in long COVID.”
It is also a welcome departure from earlier studies, which suggested that
vaccines provided only a modest defense against long COVID. In 2022 Marra’s
team published a meta-analysis of six studies that found that a single dose of
the COVID vaccine reduced the likelihood of long COVID by 30 percent. Now, that
protection appears to be much greater."
