Experts don’t know yet because they’re still studying vaccinated people to see when protection might wear off. How well the vaccines work against emerging variants will also determine if, when and how often additional shots might be needed.
“We only have information for as long as the vaccines have been studied,” said Deborah Fuller, a vaccine researcher at the University of Washington. “We have to study the vaccinated population and start to see, at what point do people become vulnerable again to the virus?” So far, Pfizer’s ongoing trial indicates the company’s two-dose vaccine remains highly effective for at least six months, and likely longer. People who got Moderna’s vaccine also still had notable levels of virus-fighting antibodies six months after the second required shot.
Antibodies also don’t tell the whole story. To fight off intruders like viruses, our immune systems also have another line of defense called B and T cells, some of which can hang around long after antibody levels dwindle. If they encounter the same virus in the future, those battle-tested cells could potentially spring into action more quickly.
Even if they don’t prevent illness entirely, they could help blunt its severity. But exactly what role such “memory” cells might play with the coronavirus -- and for how long -- isn’t yet known.While the current COVID-19 vaccines will likely last for at least about a year, they probably won’t offer lifelong protection, as with measles shots, said Dr. Kathleen Neuzil, a vaccine expert at the University of Maryland.

HeyHelina What constitutes a subject in these studies?
My body is not a software that Bill Gates can update. Also, how reassuring that you can’t even tell us how long this vaccine will work, or why it’s fucking with women’s periods. vaccinated VaccinesWork VaccineForAll vaccine NoVaccinePassports KnowYourVaccine Moderna
