The CDC says some people might need a fourth shot of the mRNA COVID-19 shot. 

Those are the Pfizer and Moderna vaccines. 

Research showed a booster enhanced the antibody response to the vaccine in certain people with compromised immune systems. 

At this point, the CDC has only authorized a third dose for certain immunocompromised adults.
