I seem to recall someone saying that "vaccines are a byproduct of the devil, don't take one"

I wonder on how do I speak up to them about this... those ppl that says that are my parents...

I just want to tell to them that vaccines are good...

So how do vaccines help? Vaccines can contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.
