Morphology

quadrivalent = valent (semi-transparent) = quadri + valent

The word is built from the clear prefix 'quadri-' meaning four plus the base 'valent', but the vaccine sense is a specialized scientific usage rather than an everyday compositional meaning.

Etymology

Quadrivalent comes from quadri- 'four' and valent 'power', so a quadrivalent vaccine is one that protects against four different strains of a disease.
