Can mmr cause autism?

No: Although it is likely that environmental exposures have contributed to the recent rise in autism, there is no credible evidence that the MMR vaccine has caused or contributed to increased autism. The study that first raised the concern has now been discredited as fraudulent. Autism is more common in babies born near superfund sites or with high levels of organophosphate pesticides.

NO : This is a very well studied question surrounded by lots of controversy. Scientifically speaking there is no risk of autsim associated with the MMR vaccine. It is very safe and helps prevents these serious infectious diseases.

No: There has never been a proven link between MMR and autism. Autism is caused by multiple factors, including genetics, but not vaccines.

No: Some people have been worried about the thimerosal in vaccines causing autism. First off, MMR does not contain any thimerosal and secondly thimerosal does not stay in the body long enough to build up and reach harmful levels. Vaccines are monitored very closely and are only approved if they are safe for children.

No: There is no evidence that vaccines cause autism. The cause of autism is most likely multifactorial. Unfortunately, due to some very bad, no discredited research, many children went unvaccinated and some of those died from preventable diseases.

Time to shift focus: Can the MMR vaccine cause autism? As child psychologist and mataternal-fetal specialist, I am advocate for families affected by autism. As scientist, i must follow the facts at this time--no relationship. But there is much we do not know. So we need to continue research into all possible causes of autism while also funding work on helping children achieve the highest level of functioning possible.

Certainly not.: In my practice I have no more than 20 families that have refused all vaccinations. 3 of them have autistic children, which gives an incidence of 1 in 7 - far higher than any described in vaccinated populations. I'm not suggesting that MMR "protects" against autism, but whatever caused the disease of vaccine refusal in adults is clearly affecting many of their children as well.

NO!!!!: There is not 1 shred of scientific evidence connecting MMR with autism. In fact, a recent review of 1000 research articles all reaffirmed no connection. Let us put this false notion to bed, once and for all.

Probably not: The literature has found no causal link between MMR and autism. Might there be a link for certain children? Unknown. It is hard to hear thousands of parents say "my child was fine until he/she got this "x" vaccine. If you have concerns about it, delay giving it until after age 2. Autism as a naturally occurring genetic disorder will appear by age 2.

No. : This myth has been devisably dispelled by great research. Unequivocally MMR vaccine does not cause or predispose to autism. Nor does any other vaccine. Avoidance of vaccination by wary but misguided parents has lead to a world wide increase in whooping cough, measles, rubella, and other preventable infectious diseases.

No: There was a small study many years ago funded ( fraudulently not disclosed) by the anti vaccine lobbyist lawyers which resulted in some suggestion of this. It was later retracted by the Lancet when this was disclosed. Many subsequent years of global research has not shown any association. Many children have died from the devastating effects of this misinformation.
