A.M.
there is a ton of garbage on the internet regarding vaccinations. you seem to have found some of it. The sites to go for information that is medically accurate are www.cdc.gov (centers for disease control and prevention), the american academy of pediatrics www.aap.org, the institute of medicine - they have done several very well researched studies on vaccine safety. The side effects of vaccines include redness at the site of injection (like any injection), sometimes a rash and yes it hurts. When I was getting my little one her vaccinations at 6 months, I would sit her on my lap and have my breast ready for immediate nursing for comfort. She would wail and then within a few minutes of the vaccination, she would be happily nursing and it was then all over. The diseases that a child can get that she is vaccinated against are deadly. Getting your child protected against them as soon as you can, is one of the best things you can do for your child. The Institute of Medicine and the National Institutes for Health have very thoroughly examined the claim that one vaccine MMR causes autism and they found definitively that it does not. It just so happens that the natural development of the signs of autism are over the first 2 years and so they are when you child is getting a lot of vaccinations.
