Immunocompromised may need a 4th COVID-19 vaccine booster, CDC says – National

Anyone with moderate or severe pre-existing conditions or illnesses may require a fourth booster shot to keep them adequately protected from COVID-19, updated guidelines from U.S. Centers for Disease Control and Prevention say.

The guidelines — made public on Monday — said that a fourth dose could be administered with any vaccine that had been approved for use, including Janssen’s one-shot dose and mixed-dose regimens.

“After completion of an mRNA primary series and an additional mRNA vaccine dose, moderately and severely immunocompromised people are eligible for a booster dose,” the updated guidelines read.

Anyone eligible for the booster should wait at least six months between their third and fourth shot, the CDC said.

Global News reached out to Health Canada for comment on a possible fourth dose for Canadians, but did not hear back at the time of publication.
