Tdap is the adolescent and adult booster vaccine for tetanus, diphtheria, and pertussis (also called whooping cough). The childhood vaccine is called DTaP. Both protect against tetanus, diphtheria and pertussis (whooping cough).
The Tdap vaccine isn’t covered by Medicare Part A (Hospital Insurance) or Medicare Part B (Medical Insurance).
Generally, Medicare prescription drug plans (Part D) cover all commercially available vaccines (like the Tdap vaccine) needed to prevent illness. Contact your Medicare drug plan for more information about coverage.
