The possibility of coronavirus reinfection has been a concern since the first reports of people getting sick again began popping up in 2020 ― while many around the globe were still in isolation. But there has been relatively little data up until this point on how widespread a phenomenon this is.
The first large-scale investigation to tackle that question was published in The Lancet this week, and it found that the vast majority of people who have had COVID-19 are indeed protected from catching it again — for at least six months. However, people ages 65 and older are far more likely than younger individuals to experience repeat infection.
