What is the DTaP vaccine?

The DTaP vaccine prevents three diseases: diphtheria (D), tetanus (T), and pertussis (aP). This product is available as a suspension and is injected into a muscle (Intramuscular Route).


This disease is a severe bacterial infection that affects the mucous membranes of the nose and throat. Due to the widespread vaccination against this disease, its prevalence is very rare in the United States. Symptoms of this disease include the following:
– Difficulty breathing
– Heart failure
– Paralysis
– Death


This disease is caused by a bacterial toxin and affects the nervous system. Painful muscle contractions, especially in the jaw and neck, are complications of this infection. Fortunately, the prevalence of this disease is very low these days. Symptoms of this disease include the following:
– Stiffness and spasm in the jaw and neck muscles
– Difficulty swallowing
– Abdominal muscle stiffness


This condition, also called Whooping cough, is a highly contagious respiratory infection. Symptoms of this disease include:
– Runny nose and nasal congestion
– Redness of the eyes
– Fever
– Cough
– Red or blue face
– Severe fatigue
– Provoke vomiting

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:

● Loss of appetite
● Vomiting
More serious complications that may occur are:

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.

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).
