Well Vaccine Awareness Week has begun and so I thought I’d make a list of just a few major flaws in the vaccine/autism hypothesis that anti-vaxxers have yet to satisfactorily explain and which they like to avoid like the plague with endless bullshit excuses.
Here are some of the inconvenient facts that thoroughly debunk the notion that autism is caused by vaccines or is significantly contributed to by vaccines:
Fact 1. Autism is just as prevalent among unvaccinated populations as vaccinated ones.
Fact 2. Autism is four times more prevalent in boys than girls despite both receiving the same vaccines on the same schedule.
Fact 3. If one identical twin has autism, the other twin has an 80% chance of also being autistic, regardless of vaccination.
Fact 4. Fraternal twins or siblings of individuals with autism have a 50% chance of also being autistic, regardless of vaccination.
Fact 5. New Jersey has the sixth lowest vaccination in the U.S. but is number one in autism.
Fact 6. The immunologic load has dropped from 3000 components in the 7 vaccines used in 1980 to less than 200 in the 14 vaccines recommended today.
Fact 7. An infant’s immune system is capable of handling the thousands of antigens it is exposed to early in life.
Fact 8. Vaccinated children are not more susceptible to infections.
Fact 9. Autism is not an autoimmune disease.
The last four have even be reaffirmed in a recent study published in the journal American Family Physician.
The vaccine/autism hypothesis is dead. It failed to survive even the slightest bit of scrutiny. Anti-vaxxers need to get over it. Of course, sadly, they can’t. They’ll never give it up. Denialists are immune (no pun intended) to disconfirming evidence.

I agree with all these points except the following, which is NOT a good argument:
“Fact 2. Autism is four times more prevalent in boys than girls despite both receiving the same vaccines on the same schedule.”
If vaccination were a cause of autism, there’s nothing to say that one gender wouldn’t be more susceptible to the condition than the other. Otherwise, the rest of your points make sense.
What fact 2 demonstrates is that genetic or hormonal factors are involved, something many in the anti-vaccine movement deny.
