(KYMA, KECY) - The Centers for Disease Control and Prevention (CDC) now says certain people who are immunocompromised may need a fourth MRNA COVID-19 shot.
Those people can get that fourth shot at least 6 months after getting their third shot.
The MRNA vaccines available in the U.S. are the Pfizer and Moderna vaccines.
Research showed that a booster dose enhanced the antibody response to the vaccine in certain immunocompromised people.
This comes after the CDC authorized a third dose for certain immunocompromised people 18 and older in August.
