Talk to Patients About: Diphtheria - 09/11/2023
Diphtheria infected more than 200,000 and killed 15,000 in
the U.S. in 1920, but the growing use of vaccines during that decade caused
rates to drop, the U.S. Centers for Disease Control and Prevention (CDC) says.
In the 1940s, the diphtheria vaccine was combined with tetanus and pertussis,
and the shot became routine for children. Between 2004 and 2017, only two U.S.
cases were reported, CDC says.
