My babies always feel out of sorts after a series of vaccines. Their body temperature would rise, as well as their fussiness. My pediatrician routinely advises to give them some Tylenol to make them feel better. Apparently - not a good idea.
An international research team led by Roman Prymula, MD, of the University of Defense, Czech Republic, finds that Acetaminophen, the active ingredient in Tylenol, weakens infants’ immune responses to vaccines.
In a study looking at whether acetaminophen really prevents vaccine-related fever, Prymula and colleagues found that the common over-the-counter pain remedy dampens vaccine-induced immune responses.
