booster shot

Follow-up jab

A booster shot is an additional dose of a vaccine given after the initial vaccination series to restore or enhance immunity that may have waned over time.

Unlike the primary doses that establish protection, boosters serve as reminders to the immune system, prompting it to maintain its defenses against a particular disease.

I need to get my tetanus booster—it's been over ten years.

The term gained widespread familiarity during COVID-19 vaccination campaigns.
