Immunity To COVID-19 Could Last Longer Than You'd Think

All around the world, there seem to be signs that immunity to SARS-CoV-2 doesn't last very long after you're vaccinated.

Israel is now having one of the worst COVID surges in the world about five months after vaccinating a majority of its population. And here in the U.S., health officials are recommending a booster shot eight months after the original vaccine course.



So how long does immunity last after two doses of the vaccine? Six months or so? And at that point, how much protection is left over?

It all depends on which type of immunity you're talking about, says immunologist Ali Ellebedy at Washington University in St. Louis. Six months after your vaccine, your body may be more ready to fight off the coronavirus than you might think.
