giving acetaminophen (Tylenol, etc) to kids before vaccinations might lower the body's immune response

New evidence suggests that giving acetaminophen (Tylenol, etc) to kids before vaccinations might lower the body's immune response.

This is important...a lower immune response means the vaccine might not work as well as it should to protect against disease.

And many parents give their child acetaminophen before immunizations to prevent injection pain, fever, and fussiness.
