This vaccine helps prevent:
- Diphtheria—which causes a sore throat with thick covering in the back of the throat
- Tetanus—which causes painful muscle tightening all over the body; also known as lockjaw
- Pertussis—which causes bad coughing spells that make it difficult for infants to eat, drink, and breathe; also known as whooping cough
The Tdap vaccine contains diphtheria and tetanus toxoids, and acellular (small, purified pieces) pertussis germ.
is given to children ≥ 7 years old, adolescents, and adults to protect against tetanus, diphtheria, and
The vaccine is given as an injection, usually into the arm or thigh.
Tdap is routinely recommended for children aged 11 years or older, regardless of whether or not they completed the DTaP series. Tdap can also be given to:
- Children aged 7-10 years who have not been fully vaccinated
- Children (aged 11 years and older) and adults who did not get the Tdap should receive the vaccine followed by a tetanus and diphtheria (Td) booster every 10 years
- Adults who

tetanus, diphtheria, and pertussis, talk to the doctor.

- Fever over 102ºF
- Severe gastrointestinal problems
- Severe headache
is sometimes given to reduce pain and fever that may occur after getting a vaccine. In infants, the medication
may weaken the vaccine's effectiveness. However, in children at risk for seizures, a fever lowering
may be important to take. Discuss the risks and benefits of taking acetaminophen with your doctor.
Most people should receive their vaccinations on schedule. However, individuals in whom the risks of vaccination outweigh the benefits include people who:
- Have had a life-threatening allergic reaction to Tdap
- Have had a severe allergy to any component of the vaccine to be given

The best way to prevent diphtheria is to get vaccinated.
Promptly clean all wounds and follow-up with your doctor for medical care to prevent a tetanus infection.
You can help prevent pertussis by keeping infants and other people at high risk away from infected people.
In the event of a
outbreak, all people who may have been exposed should be brought up to date with the vaccination. It is important to protect infants by isolating those who have the infection. Diagnosing the disease as quickly as possible can help control future outbreaks.
