Vaccine-Preventable Diseases

Diphtheria (DTaP, Tdap, Td)

Diphtheria is a serious disease caused by bacteria. The actual disease is caused when the bacteria release a toxin, or poison, into a person's body.
Diphtheria bacteria live in the mouth, throat, and nose of an infected person and can be passed to others by coughing or sneezing. Occasionally, transmission occurs from skin sores or through articles soiled with oozing from sores of infected people.
Diphtheria can lead to severe breathing problems, heart problems, and paralysis. Death occurs in 5%–10% of people infected with diphtheria.
Diphtheria was once a greatly feared illness in the United States. In the 1920s, there were between 100,000 and 200,000 cases of diphtheria each year with 13,000–15,000 deaths. Because of widespread immunization and better living conditions, diphtheria is now rare in the United States.
Vaccination is the most effective step you can take to be protected from this serious disease.
Diphtheria Vaccine Schedule
All children should get 5 doses of DTaP (diphtheria-tetanus-pertussis) vaccine, beginning when they're 2 months old. If your child misses a dose or gets behind schedule, make sure they get the next dose as soon as possible. Older children, teens, and adults should receive Tdap vaccine and after that, a Td booster dose every 10 years.
