Anti-vaxxer 

An anti-vaxxer is a person who generally believes that vaccines are the main cause of diseases, they are generally middle-aged (45 to 65) moms who have one or more children.

These people will disharmonize (disagree) with every piece of scientific research thrown at them. They tend to get their facts from one or two websites or a paper that caused the MMR vaccine controversy
A controversy surrounding the combined measles, mumps, and rubella (MMR) vaccine started with the 1998 publication of a fraudulent research paper in The Lancet linking the vaccine to colitis and autism spectrum disorders

These people also believe that everyone is paid by big pharama and that every scientist in the world is a fraud paid by the government.

Anti-vax moms tend to spread their malarkey to their children, plus they don't vaccinate them, which is a big problem since then the child can be a carrier of an eradicated vaccine and then it could spread it to other people.

Sadly, some unvaccinated kids COULD die of measles at the age of 3, as shown by a study done in 1986, This shows how unknowledgeable they are and how they can put their children and others lives in danger.

"Hey, Bertha did you hear that the H1N1 flu vaccine causes AUTISM?"
"Oh golly Margaret I didn't know! I'd rather have my kid die of a completely eradicated disease than have it have autism!"
"Oh I agree with you Bertha, I'm so happy that I opened my eyes and became an anti-vaxxer"

anti-vaxxer 

A nutjob who rejects modern science and medical knowledge in favour of conspiracy theories, urban legends, and general crackpottery. Ironically, they shrilly denounce the evils of pharmaceuticals and doctors from behind the keyboard of their own computer - a product of that same science they reject.

Another term, arguably more accurate, is "pro diseaser".

Thanks to anti-vaxxers, diseases like measles, whooping cough and diphtheria that were practically non-existent are making a comeback. Great job, guys.

anti-vaxxer 

A fool who chooses to endanger him/herself, his/her family and society as a whole by refusing to vaccinate him/herself and his/her children against dangerous diseases. Anti-vaxxers are typically gullible people who lack a basic understanding of chemistry, biology and medicine.

Thanks to the anti-vaxxers, diseases like measles and pertussis are making a comeback.

anti-vaxxer 

Small minded, paranoid person who thinks they understand science but they really don't. Convinced of their own self righteousness as they tend to congregate in echo-chamber like groups which espouse 'big pharma' conspiracy theories. Often rely on 'natural' healing such as homeopathy and claim these work better than evidence based medicine.

Anti-vaxxer's are the reason many communicable diseases are on the rise, such as measles and whooping cough

1. A person who opposes vaccinations despite scientific evidence. Often associated with a fear that they cause autism.

2. Slang for someone who refuses to acknowledge obvious facts because they're contrary to their preconceptions.

Those stupid anti-vaxxers have brought back previously defeated illnesses like measles and mumps all over the country.

Did you hear Jill try to argue that Ken Ham won the debate with Billy Nye? She's such a delusional Anti-vaxxer!.
