I thought I would offer you a little bit of re-assurance:
From Wikipedia, the free encyclopedia
The MMR vaccine controversy is over the safety of the MMR vaccine. Critics of the vaccine say that the incidence of autism has greatly increased and that the vaccine is a primary cause of this increase. They posit that the vaccine can overwhelm the young immune system, which they assert is often already struggling from the effects of other environmental factors such as exposure to heavy metals. Critics also say that the live measles virus in the formulation of the MMR harms susceptible individuals in a way that wild measles does not.
The consensus of the medical and scientific community is that the vaccine's benefits greatly outweigh its risks, and that there is no scientific evidence to support the critics' claims of a link between MMR and autism. The Centers for Disease Control, the Institute of Medicine of the National Academy of Sciences, and the UK National Health Service have all concluded that there is no evidence of a link between the MMR vaccine and autism. A systematic review by the Cochrane Library concluded that there is no credible link between the MMR vaccine and autism, that MMR has prevented diseases that still carry a heavy burden of death and complications, and that the lack of confidence in MMR has damaged public health.
While there are always risks with everything we do, the benifits so strongly outweigh any supposed risks. I dont know if you have done any research on the diseases this vaccine protects against, if you have not, I think you should. The best tool we have is education! My kids are almost 3 and 20 months old, fully vaccinated, and they are just fine!!
I hope this helps you with your delima!! Happy day to you.
