A U.S. government study has reassuring news for concerned parents — vaccines rarely trigger serious and potentially fatal allergic reactions.
Just 33 people had a serious, potentially life-threatening allergic reaction — also known as anaphylaxis — out of 25 million vaccines given, according to research from the U.S. Centers for Disease Control and Prevention. That’s 1.3 people in every million who gets a vaccine.
“Vaccination is one of the best ways parents can protect infants, children and teens from 16 potentially harmful diseases. This is a good time to remind parents that vaccines are safe and effective — the odds of having an anaphylaxis-related reaction following the administration of a vaccine are very slim,” said study author Dr. Michael McNeil, of the CDC.
For the study, the researchers reviewed records from more than 17 million visits and more than 25 million administered vaccines.
