How Long Are You Protected After A COVID Infection Now?

The level of protection someone gets after a COVID infection varies from person to person.

Exactly how long protection lasts after a COVID infection isn’t one-size-fits-all. A few factors make it impossible to say exactly how long you’re protected from reinfection.

Earlier in the pandemic, experts theorized most people had about a 90-day immunity window.

With these new, more transmissible variants, there is no way to predict which category you’ll fall into.

It is very hard to provide generalized guidance.”
