The CDC recommends people 5 and older receive an age-appropriate, updated mRNA booster dose if at least 2 months have passed since their primary series or since their most recent booster dose. A person can receive a booster of a COVID-19 vaccine that is different than the COVID-19 vaccine they received for their primary series or initial booster as long as it is age appropriate.

The recommended vaccination schedule from the Centers for Disease Control and Prevention is available here.
