People with certain health conditions that make them moderately or severely immunocompromised may get a fourth mRNA COVID-19 shot, according to updated guidelines from the U.S. Centers for Disease Control and Prevention.
Research showed that a booster dose enhanced the antibody response to the vaccine in certain immunocompromised people.
That would make for a fourth shot at least six months after completing the third mRNA vaccine dose. At this time, the CDC about the fourth shot. People should talk to their doctors to determine if it is necessary, the CDC says.those who are in active cancer treatment for cancers of the blood or for tumours, certain organ transplant and stem cell recipients, people with advanced or untreated HIV, and those who take a high-dose corticosteroids or other drugs that may suppress their immune systems. The CDC estimates about 9 million people who live in the U.S.
People who are immunocompromised who got the single-dose Johnson & Johnson shot should get a booster at least two months after their initial vaccine. People who choose a Moderna vaccine as a booster, even if they received a different vaccine as the first dose, should get the half-dose sized shot that was authorized as a booster for Moderna's vaccine, the CDC said.
