The last case of diphtheria wasn’t that long ago…
What’s the difference between Tdap and DTaP?
Nope. Getting the DTaP vaccine does not make you more susceptible to getting pertussis.
Many factors are responsible for the rise in pertussis outbreaks in recent years, but it is clear that being unvaccinated and unprotected put you at greatest risk for getting pertussis and passing it on to others.
