Who Should “Boost” Again?

April 12, 2022

The CDC provided guidance recommending those age 50 and older, and those 12 and older who are immunocompromised receive a second COVID-19 mRNA booster (Moderna or Pfizer) if 4 months has elapsed since their first booster. We know that immunity wanes over time, and that booster shots dramatically improve your body’s immune response to Omicron, including BA.2. NCH would encourage all those eligible who have yet to receive their first or second booster to please consider receiving it soon.

This handy chart should explain booster eligibility.
