oral vaccine
Mouth-administered shot alternative
An oral vaccine is administered by mouth rather than by injection.
The polio vaccine is the most famous example—children receive drops on the tongue or in sugar cubes.
Oral vaccines are easier to distribute in areas without trained medical staff or sterile equipment, and they can trigger immune responses in the digestive tract where many pathogens enter the body.
