Kind of vaccine

ORAL

This type is administered by mouth rather than injection, often used for diseases like polio. Think of how some medications are taken.

The clue "Kind of vaccine" hints at a type of immunization that isn’t injected but instead taken by mouth. "Oral" fits because it describes vaccines like the polio vaccine, which is administered as drops. The wordplay is straightforward—no tricks—just a direct reference to how the vaccine is given. Think of it like medicine you swallow instead of a shot.
