Andrew Wakefield was a doctor who in the 1990s developed his own measles vaccine and therefore tried to discredit the existing one. In 1993 he published a report in which he suggested that MMR vaccines cause Crohn’s disease, a claim which was soon disproved. 
The film Vaxxed is based on several false premises, the most important ones being:
Premise #1: There is an Autism Epidemic
Autism has been around as long as mankind, it just wasn’t understood before Hans Asperger did the first study on the subject. Some of us were hidden away, dumped in institutions or killed for being ‘retarded’, others struggled all their lives to be accepted or at least tolerated. While I agree that not every historic person can be diagnosed posthumously for having a single trait or by anecdotal evidence, there are many cases whose biographies provide sufficient evidence that they were autistic, such as Galilei, Michelangelo, Shakespeare, Beethoven and Einstein, to name but a few.
Premise #2: Children can Develop Autism
Autistic people are autistic from the moment of conception. While some suggest that other factors may be involved, it is generally accepted by scientists that the genetic factor is by far the most predominant if not the only one. 
Premise #3: Dead Children are Better than Autistic Children
This, of course, is not a matter of science but a matter of opinion. However, autistic individuals and most of our parents will tell you that we disagree.
The film revolves around the voice of Will Thompson, a research scientist at the CDC (Center for Disease Control and Prevention) who supposedly ‘blew the whistle’ on his employer about documents that, as the film wrongfully claims, support Wakefield’s disproved assertion that MMR vaccines cause autism and whose phone calls with biologist Brian Hooker were recorded.
Hooker, who has an autistic child, receives a phone call out of the blue.
Under the headline Did the CDC commit fraud?, the filmmakers purport to provide evidence of a CNC cover-up which, however, fails to withstand scrutiny:
The film also claims that no study has ever compared vaccinated and unvaccinated children regarding their risk of autism.
One of the recurring features of the film are anecdotal accounts of children being diagnosed with autism around the time of their vaccination.
In order to portray autism as something to be feared and abhorred, autistic children are shown at their worst, and most likely without their consent. They are showcased as either aggressive or despondent, and their parents’ wish to have a different child is discussed in their very presence; it may not always be obvious, but autistic children understand very well what is being said, even if it doesn’t look like it.
Vaxxed paints a picture of autistic children being obstacles in their parents’ lives, or at best an object that has no value, no identity, no feelings and no idea about what’s going on around them and does not require any affection or even respect.
The filmmakers also use a multitude of daunting made-up statistics, diagrams and prognoses to get their point across.
After members of Hear This Well, another anti-science group opposing vaccines, are introduced, we are greeted by a dawn chorus of zombies, repeatedly chanting their unholy mantras ‘Vaccines cause autism’ and ‘Hear this well’.
Ironically, Wakefield can rightfully claim that he doesn’t tell parents not to vaccinate their children; sometimes he suggests to split the MMR into three separate vaccines (in which case he would profit from selling his own measles vaccine), and sometimes he suggests to vaccinate children at a later age. But nonetheless, in the hysteria he purposely created with his fraud, parents don’t vaccinate their children at all, and children will continue to die because of his propaganda.
The film concludes with the following demands:
While I am perfectly aware that the pharmaceutical industry, just like any other, would put their profit before any other concern, a man who tries to discredit the existing vaccines in order to market his own, who makes a fortune by offering quack cures and who is responsible for all recent measles deaths in the Western world accusing ‘Big Pharma’ of a cover-up for financial gain is not a person I could take seriously - and neither should anybody else.
Let me leave you with ‘whistleblower’ Will Thompson’s own words (from his only public statement):
By the way, you may have noticed that I haven’t used the term ‘documentary’. The Collins dictionary defines the word as 'a factual film or television programme about an event, person, etc, presenting the facts with little or no fiction', which does not apply to Vaxxed.
Vaxxed is a B horror film which may entertain with some shocking effects and emotional appeals, but its storyline fails miserably in view of the facts, even for a work of fiction.
The film is strongly opposed by scientists, the scientifically educated public and autism rights activists, and many of these think that the film, due to its misleading nature and possibly disastrous effect on public health, should be banned.
Also, while claiming to expose what they call a ‘catastrophe’, the filmmakers insist that people pay to see the film instead of making it available to everybody. As an interviewer phrased it, ‘they're spreading the fear, but they're charging for it.’
