revaccinations
Additional vaccine doses
Revaccinations are repeated vaccinations, given after an initial vaccination to maintain or restore immunity.
Some vaccines require scheduled revaccinations at set intervals; others become necessary when immunity wanes or a new variant emerges: The clinic offered free revaccinations for healthcare workers.
Also called booster shots or boosters.
