Who is eligible for a COVID-19 booster shot now?

Currently, the Centers for Disease Control and Prevention only recommends COVID-19 vaccine stimulators for people with moderate to severe immunosuppression.

This includes people who have received an organ or stem cell transplant, people with advanced HIV, people who are being treated for blood cancers, and people who are taking high doses of corticosteroids or other immunosuppressive drugs.

Immunocompromised people may receive a booster shot if at least four weeks have passed since their second dose of Pfizer or Moderna. They can get the third dose anywhere vaccines are available. According to New York Times reports, nearly a million booster doses have already been administered.

The launch of the Johnson & Johnson single-dose vaccine began in March, several months after the mRNA dose vaccines.

Last week, Johnson & Johnson said it had preliminary results from a small clinical trial. In the trial, people received a second dose of the vaccine six months after the first dose. The data have indicated some benefit for reinforcement, but have not yet been peer-reviewed or published in a study.

Deepta Bhattacharya, a professor of immunobiology at the University of Arizona School of Medicine, said most immunologists think people who receive this trait are likely to need some kind of reinforcement.
