Some children experience common side effects of DTaP including: short-term fussiness; inflammation; mild fever, warmth of skin; sleepiness; soreness, itching or swelling at the injection site; loss of appetite and achiness. Side effects usually subside in time. It is important to tell your doctor if any side effects become serious or persist because that may indicate your child should not receive more doses of the vaccine. Many of the following side effects are rare, but if your child experiences any of the following after receiving DTaP, see your doctor as soon as possible: allergic reaction (including breathing trouble, hives, rash or swelling in the face or throat); extreme sleepiness or loss of consciousness; fussiness or agitation that lasts for more than an hour; seizures or convulsions; or a high fever which can appear up to four days after the vaccination.
