CDC strengthened its recommendation that those 12 and older who are immunocompromised and those 50 and older should receive a second booster dose of an mRNA vaccine at least 4 months after their initial booster. People who received the Johnsons & Johnson vaccine for their primary and booster vaccinations should also receive a second booster of an mRNA vaccine 4 months after their initial Johnson & Johnson booster.

Since April, cases of COVID-19 have steadily increased and there has been a steep and substantial increase in hospitalizations for older Americans. While older Americans have the highest coverage of any age group of first booster doses, most older Americans received their last dose (either their primary series or their first booster dose) many months ago, leaving many who are vulnerable without the protection they may need to prevent severe disease, hospitalization, and death.

Whether it is your first booster, or your second, if you haven’t had a vaccine dose since the beginning of December 2021 and you are eligible, now is the time to get one. Learn more about eligibility and data supporting boosters.
