Someone who does their own "research" and "draws their own conclusions" about vaccination if that research consists only of confirmation of their pre-existing biases and drawing their own conclusion means subscribing to whatever fearmongering conspiracy is popular at that particular moment
John thinks that vaccines cause autism after using anti-vaxxer sites as his sole source of information

Get the anti-vaxxer mug.
Someone who chooses to ignore decades of scientific research and statistics that prove the efficacy, safety, and success of modern vaccinations.
Anti-vaxxers are complete loonies that believe in conspiracy theories, and base their beliefs on

Someone who completely rejects science in favor of endangering themselves and others with preventable diseases.

Get the anti-vaxxer mug.
A person who, because of a lack of understanding of immunology, biology, chemistry, or just science in general, refuses to allow vaccination of themselves or their children.

Often talk about vaccines causing autism and/or other diseases, despite the fact that most evidence pointing to that has been widely discredited and retracted.

Will resort to flinging insults when questioned. May say that you need to "do your own research" (just not in a lab); that doctors and scientists are all bought out or are "shills" for "Big Pharma" or the government, and are planning on killing everyone; or that they are the only ones that are "AWAKE1!1!!1!!".

Only rarely show sympathy to anyone but themselves. Slight chance of germ theory denial. If sighted, do not approach: often armed and contagious.
Despite an enormous body of evidence that vaccinations have caused a decrease in polio outbreaks from 350,000 in 1988 to some 416 cases in 2013, anti-vaxxers continue to both deny the efficacy of vaccines and push the discredited idea that vaccines cause autism.

This has caused an increase in the cases of preventable diseases such as measles, including a Disneyland outbreak in early 2015.

A person that thinks reading made up stuff about vaccines on the internet actually equals research.
The anti-vaxxer had no clue as usual.

Get the anti-vaxxer mug.
Someone who, despite abundant scientific research and studies showing the opposite, believes that vaccines are dangerous, and instead turns to ineffective "placebo" methods of keeping themselves well.
Anti-vaxxers compromise the well-being of themselves and everyone around them.

Get the anti-vaxxer mug.
Opposed to the use of vaccines; despite the overwhelming scientific consensus that vaccines are safe and effective.
Will often resort to retracted and debunked research papers (some decades old) and conspiracy theories to back up their claims.
"Did he really just cite Wakefield?"
"Yeah, next we'll be hearing about mercury and lizard people, typical anti-vaxxer tripe".
