Vaccines Cause Autism
If you are active on social media, you must have run into the anti-vax crowd. The anti-vax group believes that vaccines can cause many problems, including autism. They share a lot of conspiracies that involve Big Pharma.
There has been extensive research trying to link vaccines to autism, and all have become empty. Vaccines do not cause autism. Before being released, vaccines undergo a long testing period before they are deemed safe for the public.
