Doesn't this come down to a "you can't prove a negative" argument? If there were proof that vaccines were dangerous then the (real, not Internet wannabe) media would be all over it. I don't have one scientist in my friend group who is anti-vacc. I see a lot of people who claim to be, in an arena where that cannot be checked, claiming to know better.
All I know is that in my peer group I knew no one who had whooping cough, measles, mumps etc.
I knew three people (children) who died of meningitis before the vaccine (I've known none since). I know one adult who died of chicken pox as an adult. I know three people who are pensioners and were disabled and in pain for life due to having polio as a child.
I know no one whose child changed in any way after vaccinations.
Now this isn't research. It's not statistically showing anything. But in the past few years whooping cough and measles have been local illnesses. I have been frightened my babies could contract them. I have been terrified for those who cannot immunise due to medical reasons.
These illnesses were practically non-existent where I live, and now they're back. Children who are not protected by vaccine will die. They will suffer preventable brain damage and death. It's only a matter of time. These illnesses were potentially fatal.
I would like every anti-vaccer to have to speak to someone who had polio as a child, or measles, or mumps or any of the illnesses we can prevent. I'd like them to speak to mothers who caught rubella whilst pregnant and to tell them "but there's a bit of aluminium in it"
It's so hard, because I don't think anyone has a right to do anything to anyone's child without their permission. But I also don't think that you have a right to endanger my child with your choices.
Could we have anti-vaccers schools? Where they couldn't join my child in class, but would have the same education. That way the school my child goes to has the benefit of herd immunity, and with fewer spaces to spread disease, even the antivaccers would get more protection. Obviously if there was an outbreak it would be disastrous for the antivacc school.
