I was vaccinated, and I am still vaccinated (given the influenza shot every year). I think it can really seem to some people as though vaccines cause autism, especially with all the anti-vax stories out there of typically developing children who it seems suddenly "became autistic" overnight, but I have a theory for this. There hasn't been a load of research into this topic, and I am no expert, but I don't believe parents are 'entirely' wrong when it comes to harmful effects of vaccines. I, however, do not believe that vaccines cause autism, as in, autism spectrum disorder, and this myth has been debunked time and time again. Unfortunately, a disease that looks a great deal of a lot like autism can crop up around the same time after receiving the MMR vaccine in particular.
This is just my personal opinion, but I believe that many, if not most of the cases involving regressive autism (after receiving MMR) are actually due to a mitochondrial disease. Mitochondrial diseases are a group of diseases in which the mitochondria (powerhouse of the cell) cannot efficiently turn oxygen and sugar into energy, which leads to cells not working correctly. Not everyone with one of these diseases will show symptoms. The group of mitochondrial diseases that tend to affect children usually appear with symptoms at a young age, though, and can be brought on by experiences of physical stress on the body.
Now, oftentimes after a child receives the scheduled MMR vaccine, parents report the child coming down with a fever, which is fairly typical. They may also experience febrile seizures, a rash, loss of appetite, and fussiness. These are all typical to some degree, but as mitochondrial diseases can be brought on/exemplified by times of physical stress (illness, high fever, malnutrition, dehydration, etc.) it just seems to make sense to me that children who receive the MMR vaccine, come down with a fever, and then have regression of some sort may actually have a form of mitochondrial disease. When mitochondrial disease affects the brain, it can trigger a regressive encephalopathy, or a disease in the brain that makes a person lose skills they once had acquired. These can be skills such as walking, talking, or even being social, and thus mimicking the symptoms of an autistic spectrum disorder.
I'm not saying that every case of regressive autism or autism with a regressive encephalopathy is actually "hidden mitochondrial disease", but there certainly does seem to be an unknown link of some sort. I am particularly skeptical of cases in which parent or caregivers claim their child to have become autistic after describing a fever/seizures as well as continuous regression after receiving the MMR vaccine. Again, please don't bite my head off, this is all my opinion, and I am definitely no medical professional or expert, but what I do believe is that there seems to be a pattern in cases of regressive autism after receiving vaccines that may point towards a mitochondrial disease.
