The CDC recommends people 6 months and older who got the Moderna vaccine receive an age-appropriate updated mRNA booster dose if at least 2 months have passed since their primary vaccination series or since their most recent booster dose.
The CDC recommends that people stay up to date with their vaccinations and get boosted when eligible. Use CDC’s COVID-19 vaccination schedule, or answer a few questions on the CDC website to make sure you are up to date.
