What Is Diphtheria?
Diphtheria is a highly contagious infection. It can be life-threatening. It is caused by a bacterium called Corynebacterium diphtheriae. The germ produces a toxin that can spread from the site of infection to other tissues in the body. Diphtheria usually affects the throat and nose. In serious cases, it may affect the nervous system and heart.
Diphtheria spreads easily from person to person by coughing or sneezing. People nearby breathe in the infected droplets. In rare cases, they come into direct contact with elements from an infected person’s mouth, nose, throat, or skin.
Because of a widespread immunization program, diphtheria is now rare in the US.
What Is the Diphtheria Vaccine?
The diphtheria vaccine is an inactivated toxin called a toxoid. There are different types of the vaccines to prevent diphtheria, including:
- DTaP—given to children to protect against diphtheria, tetanus, and pertussis
- DT—given to children who cannot receive the pertussis part of the DTaP vaccine
- Tdap—given to children, adolescents, and adults to protect against tetanus, diphtheria, and pertussis
- Td—given to adolescents and adults to protect against tetanus and diphtheria
The vaccine is injected into the muscle.

DTap
The DTaP vaccine is generally required before starting school. The regular immunization schedule is to give the vaccine at:
- 2 months
- 4 months
- 6 months
- 15-18 months
- 4-6 years
Tdap
Tdap is routinely recommended for children aged 11-12 years who have completed the DTaP series. Tdap can also be given to:
- Children aged 7-10 years who have not been fully vaccinated
- Children and teens aged 13-18 years who did not get the Tdap when they were 11-12 years old
- Adults who have never received Tdap
- Pregnant women after 20 weeks of pregnancy who have not previously received Tdap
- Adults who have not been previously vaccinated and who have contact with babies aged 12 months or younger
- Healthcare providers who have not received Tdap
Td
Td is given as a booster shot every 10 years.
Catch-Up Schedule
Talk to a doctor if you or your child has not been fully vaccinated against tetanus. .
What Are the Risks Associated With the Diphtheria Vaccine?
Most people do not have problems with the diphtheria vaccine, but it sometimes causes:
DTaP
- Mild: fever, irritability, tiredness, poor appetite, vomiting; redness, swelling, and tenderness at the injection site
- More serious complications: seizure, non-stop crying, fever over 105° F, allergic reaction. Very rare reactions may include long-term seizures, brain damage, and coma
Tdap
- Mild: pain, redness or swelling at the site of the injection, mild fever of at least 100.4° F, headache, tiredness, nausea, vomiting, diarrhea, chills, sore joints, rash, swollen glands
- More serious complications: fever over 102° F; extensive swelling, severe pain, bleeding, and redness in the arm where the shot was given
Td
- Mild: pain, redness or swelling at the injection site, mild fever, headache, tiredness
- More serious complications: fever over 102° F, extensive swelling, severe pain, bleeding, and redness in the arm where the shot was given
Acetaminophen (eg, Tylenol) is sometimes given to reduce pain and fever that may occur after getting a vaccine. In infants, the medicine may make the vaccine weak. Talk with your doctor about the risks and benefits of taking acetaminophen. For children who have had a seizure in the past, controlling any fever may be important.
