Morphology

pentavalent = valent (transparent) = penta + valent

Compositionally 'penta-' (five) + '-valent' (having valence/capacity); extended usage to vaccines meaning 'containing five components' is predictable from the parts.

Etymology

Pentavalent combines penta- meaning 'five' (like pentagon) and -valent from the Latin valere meaning 'to be strong' or 'have power'. So a pentavalent vaccine is one that has five parts to protect against five different diseases in a single injection.
