Diphtheria
What is it?
Diphtheria is a serious, highly contagious disease caused by a toxin made by bacteria. Diphtheria causes a thick covering in the back of the throat. It can lead to breathing problems, paralysis, heart failure, and even death. It is spread through the respiratory droplets from sneezes and coughs. Diphtheria can also be spread by contaminated objects or foods. Even if an infected person doesn’t have any symptoms, they can infect others for up to four weeks.
Crowded environments, poor hygiene, and lack of immunization are all risk factors for diphtheria.
Why is it important?
Diphtheria is very rare in the U.S. and Europe, where we have been vaccinating against the disease for decades. When someone does contract the disease about 1 in 10 dies. In children younger than 5 years, as many as 1 out of 5 children who get diphtheria die.
Progress
Prior to vaccination, there were about 100,000 to 200,000 cases of diphtheria each year in the U.S. In fact, the vaccine has been so successful that there have only been five cases of diphtheria in the U.S. in the past ten years. However, there are still outbreaks of diphtheria in other parts of the world, including Eastern Europe, the Middle East, Russia, Brazil, Nigeria, Indonesia, and the Philippines. If we stopped vaccinating in the U.S. we would allow for diphtheria to enter; the disease is only a plane ride awa
Vaccine Recommendations
With the DTaP vaccine you prevent 3 diseases with 1 shot: diphtheria, tetanus, and pertussis. Children should get 5 doses of DTaP vaccine, one dose at each of the following ages:
- 2 months
- 4 months
- 6 months
- 15-18 months
- 4-6 years
Anyone who comes in contact with a baby – parents, grandparents, caregivers, siblings, plus extended family and friends – should receive the adult form of the vaccine (Tdap) to help shield or "cocoon" newborns from whooping cough. It is also recommended that pregnant women receive a Tdap vaccine during each pregnancy between weeks 27 and 36 to benefit mother and baby. When a mom-to-be is vaccinated, she passes disease-fighting antibodies onto her baby to help protect him or her after birth.
Side Effects
While the risk of DTaP vaccine causing serious allergic reaction is very small (about 1 in 1 million) common side effects of this vaccine may include:
- Fever (up to about 1 child in 4)
- Redness or swelling where the shot was given (up to about 1 child in 4)
- Soreness or tenderness where the shot was given (up to about 1 child in 4)
Other mild problems include:
- Fussiness (up to about 1 child in 3)
- Tiredness or poor appetite (up to about 1 child in 10)
- Vomiting (up to about 1 child in 50)
These problems generally occur 1-3 days after the shot.
Moderate problems may include seizure (1 in 14,000), crying for 3+ hours (1 in 1,000), or high fever (1 in 16,000).
