Mice that are briefly stressed out before receiving a vaccine develop a better immune response than mice under no psychological stress, a new study reveals. This advantageous immunity persists for at least nine months - a good chunk of a mouse lifespan - and is likely to arise because an acutely stressed immune system develops better memories for foreign invaders, the study’s authors suggest.
I think the only real honest-to-goodness health reason one might consider avoiding vaccines is that there is a link between old vaccines that contained mercury and onset of autism in children that got the vaccines. Vaccines in the past few years have been reformulated (at least the ones we got) to remove any mercury or other heavy metals, so the chances of creating an autistic child should be nil.
The other obvious, but emotional (not medical per se), reason one might avoid them is that previously happy babies scream bloody murder. Our baby had never screamed like that ever, not even remotely close. There was also this look on her face that made you think she was wondering why her loving, trustworthy parents were holding her and helping do this to her.
It was the very first time I felt like we actually did something to hurt her and she was freaked out for about 24 hours afterwards. We had to give her a little baby tylenol for the aching legs later that night, but I'll never forget those blood curdling screams. The vaccines are important to her long-term health and I would never consider skipping them, but there was certainly an emotional reason I could see short-sighted people using to not do them.
