There is a huge wealth of information on the topic that gets suppressed and 'overlooked'. The scale of the corruption is too big for most people's 'scam filter' to detect. It's the same problem with money creation and debt - the scam is so big that only a minority of people are ready to accept it could exist. Even I had to study the money creation topic about 10 times before I could accept it is as it is.
If you deep dive into the connection between autism and vaccines, including listening carefully to all the voices you can find (who have something different to say than the others), you will likely find what I did .. Which is that parents of children harmed or killed in all of this are often the most studied on the topic. Simply having letters after your name is not proof of the diligence and focus needed to truly understand a topic to it's fullest degree. 3 - 6 years of academic study in no way guarantees that a person will diligently and open mindedly appraise all data later on in their career. Those seeking to protect their children have a different signature.
From my experience of looking into autism/vaccines - there are two threads that need to be considered, but which the mainstream 'discussion' of it will rarely, if ever, even mention:
Vaccines given to babies (an absurdly disgusting idea since babies don't even have working immune systems initially so the vaccines cannot possibly benefit them) and small children have the capacity to trigger an overwhelming of the blood system. The unnatural level of pathogenic material directly entering the bloodstream from the vaccine (something that would never normally occur and that the immune system is not designed to handle perfectly) can lead to a massive surge in immune response. The adjuvants added to the vaccines create this scenario deliberately in order to try to 'make sure' the immune response is triggered. Essentially, the body is poisoned with metals such as aluminium and other crap, deliberately - from within the vaccine. Net result is that it seems that in some cases, the massive immune response can block tiny blood vessels in the brain of developing babies - leading potentially to brain damage and developmental disorders.
Many people claimed that it was Mercury in vaccines that caused autism and then studies came out to 'debunk' this idea. In truth, the majority of people I have spoken to who are involved in the topic think it is more likely that the aluminium adjuvants are responsible for a lot of the problems (and autism). Professor. Chris Exley in Britain has performed significant research on human brains to demonstrate the connection between aluminium exposure and several brain disorders, including autism. Study his work, study who tried to debunk him, notice their intent and their continued denial of the evidence presented.
We know the world contains a high percentage of extremely evil people. The democides and genocides of the entirety of human history prove this over and over again. Somehow, though, we are supposed to believe that magically the 'healthcare' and 'science' realms are immune to this problem - like people are auto vaccinated perfectly against evil when they get some letters after their name. Clearly this itself is an evil deception based on pure denial of reality.
