What study shows that Tylenol Weaken Infant Vaccines?
Oct. 15, 2009 – Acetaminophen, the active ingredient in Tylenol, weakens infants’ immune responses to vaccines, a compelling new study suggests. Infants often get a mild fever after getting vaccines. Some pediatricians routinely use acetaminophen to prevent vaccine-related fever. But that’s not a good idea, finds an international research team led by Roman Prymula, MD, of the University of Defense, Czech Republic. 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.
