booster doses
Additional vaccine injections
Booster doses are additional vaccinations given after an initial series to restore or enhance immunity that has waned over time.
The term became widely familiar during the COVID-19 pandemic: I got my booster dose last week.
Some vaccines require periodic boosters throughout life, like tetanus shots every ten years.
