Who should get the DTaP vaccine?

The DTaP vaccine is only for children under seven years of age (6 weeks through 6 years of age). Older children, adolescents, and adults should receive Tdap and Td vaccines to prevent these infectious diseases. CDC advises that children get five doses of the DTaP vaccine in the following steps:

  • Two months
  • Four months
  • Six months
  • 15–18 months
  • 4–6 years

If your child is not feeling good due to a serious illness, it is best to wait until the child has recovered then get the vaccine.

Side effects of DTaP vaccine:

Redness and swelling at the injection site

  • Fever
  • Fussiness
  • Fatigue
  • Loss of appetite
  • Vomiting

More serious complications that may occur are:

  • Seizures
  • Non-stop crying that will last for three hours or more
  • Fever above 105 ° F
  • Swelling of the entire arm or leg, especially in older children when they receive their fourth or fifth dose.
  • Long-term seizures
  • Coma
  • Lowered consciousness
  • Permanent brain damage

What is the Tdap vaccine?

This vaccine is also effective against tetanus (T), diphtheria (D), and pertussis (aP). Unlike the previous one, the Tdap vaccine is given to children over seven years of age, adolescents, and adults. This vaccine is also available as a suspension and is injected into a muscle (Intramuscular Route).


Who should get the Tdap vaccine?

Based on CDC recommendations:

  • Adolescents: They should receive a single dose of Tdap, preferably at the age of 11 or 12.
  • Pregnant women: A dose of Tdap should be given during pregnancy to protect the newborn against pertussis. Infants are at risk for life-threatening complications of pertussis. Remember that this vaccine should be given early in the third trimester of pregnancy.
  • Adults: People who have never received Tdap should get a dose of it.


In 2010 there were 27,550 reported cases of whooping cough, while in 2012, which got large outbreaks, there were more than 42,000 in the United States. You should get the Tdap vaccine at least two weeks before visiting the baby. And the mom-to-be should also receive this vaccine during her 3d trimester.

Whooping cough spreads out quickly and can cause severe illness and even death. In addition, it is highly hazardous to infants under six months of age who are too young to stay protected by vaccines from whooping cough. Babies who get whooping cough usually catch it from family, including grandparents, who may not be aware of their condition.

Director of CDC (The National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention), Nancy Messonnier CLAIMS: “That’s why parents, grandparents, and other family members must get a Tdap shot: to prevent from getting and spreading whooping cough.”

Most adults were vaccinated against whooping cough in childhood. However, protection fades away over time. Tdap is recommended for all adults, especially pregnant women and teenagers. It is vital to have a shot if you’re going to be around a baby.

Tdap vaccine protects you from whooping cough and the severe symptoms that last about ten weeks.

Side effects of Tdap vaccine

Side effects of this vaccine include:

  • Pain, redness, or swelling in the injection site
  • Mild fever
  • Headache
  • Fatigue
  • Nausea and vomiting
  • Diarrhea
  • Stomach ache
  • Chills
  • Body aches or sore joints
  • Rash and swollen glands

If you suffer from one of these complications, contact your vaccine provider immediately:

  • You have experienced allergic and dangerous symptoms after receiving the previous dose of the vaccine.
  • You have experienced symptoms such as coma, loss of consciousness, and long-term seizures after receiving the previous dose of the vaccine.
  • If you have neurological problems or seizures
  • If you have Guillain-Barré Syndrome

Difference between DTaP and Tdap vaccines

Both vaccines protect against diphtheria, tetanus, and whooping cough, but in different age groups. Children under seven should receive DTaP, and people over seven should receive Tdap. The DTaP vaccine contains a full-strength dose of all three vaccines, but the Tdap contains a full-strength dose of tetanus and a lower dose of diphtheria and whooping cough.


DTaP or Tdap vaccines and pregnancy

According to CDC recommendations, this Tdap should be used at 27 and 36 weeks. Even if a person has received the vaccine in the last ten years, they should still get it during pregnancy.


Do people still need Tdap if they have had the TDaP vaccine?

Keep in mind Tdap is used as a booster. On the other hand, the immunity of DTaP vaccine decreases over time. So despite receiving DTaP, you should still receive Tdap.
