I went to Google before and out of curiosity due to something a lecturer said I typed "Vaccination" into google.
Ignoring the Wikipedia article which the first result for nearly anything; the first 'proper' site is the fucking AVN or "Australian Vaccine Network"

"But Cthulhu they're promoting the need for vaccinations by providing valuable information to the people of Australia"
No they're not. The AVN is a group of arrogant assholes who think they know better than medical doctors. They were formerly known as the "Vaccination Awareness Network"
(formerly known as Prince).
These people are the lowest forms of life. They spread mis-information and put
Lives at risk. I feel sorry for some young mother's who don't know any better who go looking for vaccination information on google and that's the first link they see.
There is no scientific evidence that
Not vaccinating your children not only puts them at harm but also the lives of
other children; even the ones who have been vaccinated.
That is all.
Don't even get me started on that vaccination causes autisim shit
