Morphology

booster = boost (transparent) = boost + er

A medical 'booster' dose is named as something that 'boosts' immunity, a direct and regular extension.

Etymology

Booster comes from the verb boost meaning 'to renew or increase strength' and the ending -er, so it means 'something that increases power'. That's why a vaccine booster is an extra dose given to raise or renew your protection.
