It's not that MMR is unlikely to cause autism, it cannot cause autism full-stop. Autism is a neurological difference so it occurs within the second trimester of pregnancy when the brain is being formed, no vaccination can cause autism. Billions have been wasted on thousands of research projects to prove that there is absolutely no link between autism and vaccinations.
Most definitively NO. The MMR vaccine (and, all other vaccines) have absolutely NOTHING TO DO WITH AUTISM. There have been repeated clinical studies, and absolutely no tie between the MMR vaccine and any incidence of autism has been discovered. The scare was caused by bad science and desperate parents, looking for something to blame, and a news media looking for the latest sensational cause. There never was any credible reason to assume there was a tie between MMR and autism, let alone scientific evidence.
When a man Dr John Wakefield made up false evidence that there was a link between the MMR vaccine and autism. Later, the evidence was found to be proved wrong and it has been definitely certified that there is nothing wrong with the MMR vaccine and is safe to use.
MMR vaccines, as well as other vaccines, do not cause autism. Extensive research has been done into the relationship between autism and vaccines and none has been found. The doctor who originally reported a correlation has since retracted his statements, admitted his results were faked, and lost his medical license.
The combined vaccine for measles, mumps, and rubella (MMR) was claimed to cause autism or bowel disorders in some children.
MMR does not cause autism, no doctor has come to this conclusion - in fact billions have been wasted proving beyond a shadow of a doubt that vaccines do not cause autism. This is also simple common sense, autism is a neurological condition so it starts within the second trimester of pregnancy, a person is born autistic and a vaccine cannont change a persons brain to make them autistic.
The current status of the MMR/Autism link is disputed. New beliefs are appearing that bufotenin may be responsible for autism. At the moment, there is little evidence to show that MMR may be linked with autism.More recently, several clinical studies have show no statistical link between any vaccine and the incidence of autism. The MMR does not cause, nor is a contributing factor to, autism.In addition, the bufotenin theory is at this point, just a theory. It is based on the higher-than-normal levels of bufotenin detected in some autistic people, but this has not been thoroughly studied, nor has it been shown this is prevalent in the general autistic population. As of now, we really don't know much about autism, certainly nothing definitive about causes or the mechanisms by which it works.
The exact same thing that has been causing autism at any other point in history. We don't know the full cause of autism, but primarily it's considered to be a genetic mutation either in one parent or both.
The child will not get autism from an MMR vaccination. Countries with different vaccination ingredients or different vaccination schedules have increasing rates of autism, too. Research indicates that the MMR vaccination does not cause autism. Videos and descriptions of the children thought to have had autism triggered by the thimerosal-containing MMR vaccines show that they had symptoms of autism prior to the vaccination. Autism is a genetic condition that, in most cases, is assumed to have an environmental trigger in the womb or early infancy. There is the possibility that a very small portion of the people with autism have the condition triggered by a vaccination, but that number is statistically insignificant, so it is too small to be detected in scientific studies. But there is that possibility with other events, too, such as feeding your baby processed baby food or breastfeeding for less than 2 years or eating peanuts while pregnant or any other events that are not associated with autism. Hypothetically, if a child were to have autism triggered by a vaccination, it could be because of the ingredients of the vaccination, the child's stress at receiving a vaccination, the body's immune response being triggered, or some other factor involved in the process of getting a vaccination. Another potential cause for concern is the fact that human DNA is in some of the MMR vaccines. It has not been scientifically proven nor disproven but the dates match up according to what I've read. I would love to know where autism is on the rise and vaccines are not available as someone wrote previously. I wasn't aware of that.
Common risks associated with vaccines such as swelling, fever and irritation. But NOT AUTISM.
The MMR vaccine.
The MMR vaccine controvery or scandal centered around the 1998 publication of a fraudulent research paper in the medical journal. This paper claimed that colitis and autism disorders might be caused by MMR vaccine which is not true.
There are no "real" causes of autism yet, but there are theories. Autism is a disease rarely found in newborn babies that disable the child's language development and they often have trouble communicating.
