How…

Scientists don't have opposing views on thats specific thing*. It's an example used right up there with thinking the earth is flat.

One completely discredited study linked the combined MMR vaccine to a new, made up gastrointestinal disorder. That disorder was supposedly linked to autism. The guy who ran the study had financial ties to a company that manufactured a measles vaccine separate from MMR. He had a financial motive. He paid children for blood samples at his kid's party and bragged about it. He's a monster responsible for every death caused by the measles since his evil, fake, completely made up study came out.

You want to know what makes a person seem ignorant? Being anti-vax or buying into the abject nonsense that ASD is caused by vaccines.
