overvaccination

Overvaccination refers to the administration of more vaccines than necessary or beneficial, whether through excessive doses, too-frequent boosters, or vaccinations against diseases that pose little risk to the recipient.

The term appears most often in veterinary contexts, where pet owners and some practitioners question annual vaccination schedules for dogs and cats.

In human medicine, overvaccination is invoked by vaccine skeptics who argue that childhood immunization schedules are excessive, though mainstream medical consensus disputes this framing.
