Morphology

booster + shot

The meaning is directly compositional: 'booster' (an additional dose) combined with 'shot' (an injection) yields an extra vaccine injection to renew effectiveness. This noun+noun construction is semantically transparent and cross-linguistically common, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Booster shot comes from the idea that a small injection gives a 'boost' to your body's protection. Think of booster as a lift and shot as the injection; that's why it means an extra vaccine dose to increase or renew protection.
