These problems occur more often after the 4th and 5th doses of the DTaP series than after earlier doses.

Severe problems (very rare): • Serious allergic reaction (less than 1 out of a million doses) • Several other severe problems have been reported after DTaP vaccine. These include: - Long-term seizures, coma, or lowered consciousness - Permanent brain damage. These are so rare it is hard to tell if they are caused by the vaccine.

Reactions to Rotavirus Vaccine 

 Mild problems following rotavirus vaccine: • Babies might become irritable, or have mild, temporary diarrhea or vomiting after getting a dose of rotavirus vaccine.

Serious problems following rotavirus vaccine: • Intussusception is a type of bowel blockage that is treated in a hospital, and could require surgery. It happens “naturally” in some babies every year in the United States, and usually there is no known reason for it. There is also a small risk of intussusception from rotavirus vaccination, usually within a week after the 1st or 2nd vaccine dose. This additional risk is estimated to range from about 1 in 20,000 to 1 in 100,000 US infants who get rotavirus vaccine. Severe allergic reaction. Such reactions from a vaccine are very rare, estimated at fewer than 1 in a million doses, and usually happen within a few minutes to a few hours after the vaccination. As with any medicine, there is a very remote chance of a vaccine causing a serious injury or death.

Such reactions from a vaccine are very rare, estimated at fewer than 1 in a million doses, and would happen within a few minutes to a few hours after the vaccination. As with any medicine, there is a very remote chance of a vaccine causing a serious injury or death.

It is possible for these people to infect other members of their household, but this is extremely rare.

Moderate problems: • Seizure (jerking or staring) caused by fever (very rare).

Severe problems: • Pneumonia (very rare) Other serious problems, including severe brain reactions and low blood count, have been reported after chickenpox vaccination. These happen so rarely experts cannot tell whether they are caused by the vaccine or not. If they are, it is extremely rare.

This is much lower than the risk of severe complications from flu, which can be prevented by flu vaccine. • Young children who get the flu shot along with pneumococcal vaccine (PCV13) and/or DTaP vaccine at the same time might be slightly more likely to have a seizure caused by fever. Ask your doctor for more information. Tell your doctor if a child who is getting flu vaccine has ever had a seizure.
