What infection does the Tdap vaccine offer protection against?

The Tdap vaccine is specifically designed to provide protection against three infectious diseases: tetanus, diphtheria, and pertussis (whooping cough).

Tetanus is caused by a toxin produced by the bacterium Clostridium tetani, which can enter the body through wounds, especially deep puncture wounds. Diphtheria, caused by Corynebacterium diphtheriae, can lead to severe respiratory issues and complications due to the formation of a thick coating in the throat. Pertussis, or whooping cough, is caused by Bordetella pertussis and is characterized by severe coughing fits that can be particularly dangerous for infants.

The Tdap vaccine combines protection against these three diseases in a single immunization, which is essential given the potential severity of these infections. The combination vaccination is routinely recommended for adolescents and adults to ensure broad immunity and help control the spread of these diseases in the community.

The other options represent different diseases that the Tdap vaccine does not cover. Measles, mumps, and rubella are prevented by the MMR vaccine; pneumonia, meningitis, and hepatitis are associated with various vaccines, including PCV, MenACWY, and hepatitis vaccines; and influenza and RSV
