How It Works
Vaccines help your body make chemicals called antibodies to fight off the viruses and bacteria. These vaccines are given as shots (injections).
The two combined vaccines DTaP (for children) and Tdap (for teens and adults) protect against diphtheria, pertussis (whooping cough), and tetanus (lockjaw). For children, these vaccines may be combined with the vaccines for polio alone (known as the 4-in-1), or with polio and Haemophilus influenzae type b (known as the 5-in-1), or with polio, Haemophilus influenzae type b, and hepatitis B (known as the 6-in-1).
The Td booster shot is for teens and adults. It protects against tetanus and diphtheria only.
Why It Is Used
Before vaccines were available, many people became seriously ill or died from these diseases.
A total of five shots of DTaP are given at 2 months, 4 months, 6 months, 18 months, and between 4 to 6 years of age. If the 6-in-1 or 5-in-1 shot is used, the last dose given will be the 4-in-1 (it will not contain Hib).
For children older than 7 who did not have the DTaP vaccine series, three shots of Tdap will be given.
A booster shot of Tdap is given to teens between 14 to 16 years of age.
The National Advisory Committee on Immunizations (NACI) recommends that adults get the Tdap booster shot once if they did not get it as a teen. The Td vaccine is usually given to adults as a booster shot. You should continue to get a Td booster every 10 years throughout life, unless you have been injured. You should receive a booster as soon as possible if your wound is dirty and it has been 5 years or longer since your last Td booster.
How Well It Works
The protection against diphtheria and tetanus lessens over time, which is why Td booster shots are recommended.footnote 1
In recent years, there have been more people diagnosed with pertussis. Experts think this may be because a vaccine used in the 1980s and 1990s didn't work as well as the one used today, teens and adults may lose protection over time, and more health professionals now recognize and report the disease. For these reasons, one booster shot of Tdap is recommended for teens and adults.footnote 2
Mild reactions 1 to 3 days after the DTaP shots are common, especially after the 4th and 5th doses. Your child may:footnote 3
- Have a fever.
- Have redness or swelling where the shot was given. Sometimes an arm or leg swells for 1 to 7 days after the shot.
- Be sore or tender where the shot was given.
- Be fussy or tired.
- Not feel like eating or drinking.
Mild to moderate reactions to Tdap are also common and may include:
- Pain, redness, and swelling where the shot was given.
- Nausea, vomiting, diarrhea, and stomach ache.
Even though serious allergic reactions are rare with these vaccines, call your doctor or local health unit right away if you or your child has trouble breathing, a high fever, or anything unusual after having the shot.
A person who has had a severe allergic reaction to a previous dose of the vaccine should not get another dose. Tell your doctor or nurse if you or your child has had a severe reaction to any vaccine or has severe allergies.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
Children with a mild illness, such as a cold, can get the DTaP vaccine. But if they are more ill, they should wait until they are better.
If you or your child developed Guillain-Barré syndrome (GBS) within 6 weeks of getting the tetanus vaccine, do not get any more.footnote 2 The tetanus vaccine may be linked to GBS. Talk to your doctor before having another dose of the tetanus vaccine if you or your child developed GBS within 6 weeks of having the shot.
