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

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.
