What’s going on?
The study said that most people who recovered from COVID-19 have immune cells to fight off the virus and prevent illness for eight months after the infection.
- There is a slow rate of decline after that, which suggests that “cells may persist in the body for a very, very long time to come,” according to The Seattle Times.
- The study has not been peer-reviewed or published in a scientific journal. It was published online.
- Per The Seattle Times, the findings offer some relief to experts who are worried that immunity will be short-lived.
- “That amount of memory would likely prevent the vast majority of people from getting hospitalized disease, severe disease, for many years,” said Shane Crotty, a virologist at the La Jolla Institute of Immunology who co-led the new study, according to The Seattle Times.
In November, a study found that immunity cells fight off COVID-19 within six months after the first infection, as I wrote for the Deseret News. The study said there was a “robust T-cell responses” in coronavirus patients about six months after infection.
In September, a separate study published in the New England Journal of Medicine found humans create new antibodies to fight COVID-19 one or two months after infection. The antibodies reportedly last for four months.
