Immunocompromised May Need a Fourth COVID-19 Shot, CDC Says – Slashdot

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 does not have a recommendation about the fourth shot. People should talk to their doctors to determine if it is necessary, the CDC says. 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.
