Politics is derailing a crucial debate over the immunity you get from recovering from Covid-19
WASHINGTON — Among scientists, there’s little debate: People who get sick with Covid-19 develop at least some protection against being infected in the future.
But exactly how much protection they have, and how long it lasts, are the subjects of the country’s latest Covid-19 controversy. For the past month, university employees, professional athletes, and conservative lawmakers across the country have argued they should be exempted from increasingly strict vaccine mandates because, scientifically speaking, they don’t need them: They’re already protected by their body’s own immune response.
