Which vaccine is used for diphtheria prevention?

Explanation:
Diphtheria prevention relies on the diphtheria toxoid component of the DTaP vaccine, which also includes tetanus toxoid and acellular pertussis. The diphtheria portion is a detoxified toxin that prompts the body to produce antibodies that neutralize the diphtheria toxin, preventing the characteristic illness and its serious complications. The other vaccines protect other diseases—MMR for measles, mumps, and rubella; OPV for polio; HepB for hepatitis B—so they do not provide protection against diphtheria. DTaP is used in infancy and early childhood, with boosters like Tdap given later.
