Quadracel DTaP-IPV Vaccine

Quadracel Vaccine

Quadracel is a shot that can be given as the last dose in the DTaP (diphtheria, tetanus, pertussis) or IPV (polio) series of immunizations. The most serious side effects include high fever, seizure, brain inflammation, and deadly allergic reactions.

What is Quadracel?

Quadracel® is a DTaP/IPV vaccine against diphtheria, tetanus, pertussis, and polio. It is made by Sanofi and it was approved in 2015.

What is DTaP?

Quadracel is only approved for the fifth dose in the DTaP series of vaccines against diphtheria, tetanus, and pertussis (whooping cough). DTaP is given in a series of 5 shots, one shot at each of the following ages: 2 months, 4 months, 6 months, 5-18 months, and 4-6 years old.

What is IPV?

Quadracel can be used for the last dose in the IPV (Inactivated Polio Virus) immunization schedule. Four doses of IPV are usually given at the ages of 2 months, 4 months, 6-18 months, and 4 to 6 years old.

When is each shot of Quadracel?

A single dose of Quadracel is approved for children between 4 and 6 years old. Quadracel can be given as the 5th dose in the DTaP series. Quadracel can also be given as the 4th or 5th dose in the IPV series for children who have already had 4 doses of Pentacel (DTaP/IPV/Hib) and/or Daptacel (DTaP).

Will I need more shots?

No. One shot of Quadracel is used as the final dose to complete the DTaP and IPV series of vaccines. Most adults will not need any more vaccines against polio. However, DTaP booster shots (Tdap and Td vaccines) are needed from the ages of 12-64 years old.

What are the most common side effects of Quadracel?

In clinical studies, the most common side effects where the injection was administered were pain (75%), increased arm circumference (65%), redness (55%), and swelling (40%). Other common side effects were muscle pain (50%), malaise (35%), headache (15%), and fever (6%). About 1.5% of children developed extensive swelling of the limb where the shot was given, including the elbow and/or shoulder.

What is the risk of fever from Quadracel?

Approximately 6% of children develop fevers after Quadracel. The risk was as follows: Fever over 100.4°F (2.5%), Fever over 101.3°F (2.1%), and 102.2°F (1.3%).
