Who should not get DTaP vaccine or should wait?
Children with minor illnesses, such as a cold, may be vaccinated. But children who are moderately or severely ill should usually wait until they recover before getting DTaP vaccine. Any child who had a life-threatening allergic reaction after a dose of DTaP should not get another dose. Any child who suffered a brain or nervous system disease within 7 days after a dose of DTaP should not get another dose. Talk with your doctor if your child: had a seizure or collapsed after a dose of DTaP, cried non-stop for 3 hours or more after a dose of DTaP, or had a fever over 105 °F after a dose of DTaP. Ask your healthcare provider for more information. Some of these children should not get another dose of pertussis vaccine, but may get a vaccine without pertussis, called DT.
