Actually you didn't. At least not very well. Otherwise I still wouldn't stick by my stance. People make noise supporting or going against it. Perhaps it's because people actually witnessed others getting sick from some of them or remembering times where some drugs were recalled due to too many people getting sick from it. I don't get spoon fed information, I look this stuff up, not just take people's word for it.
What would you disagree about with the following:
1. If you vaccinate millions of people, some of them will have a reaction caused by something else at about the same time as the vaccine (from simple laws of averages)
2. Some of these people will blame the vaccine (even though if you look at equavlent populations of unvaccinated people, you see *exactly the same* levels of adverse events happening at the same ages)
3. Some of these people will go on television, on the radio and the internet blaming the vaccination
4. Some people will see/hear/read this and believe that vaccines have caused harm
5. The only way to tell whether a vaccine is actually correlated with harm is to compare vaccinated and unvaccinated populations. It really doesn't matter how many "my baby got sick after his vaccination" stories you have if there's an equal proportion of "my baby got sick just after he would have had his vaccinations, but didn't".. the latter are never reported, so how would you know how many there are?
Why do people ask for evidence when they just reject it and say "Lolz you made that up. Derp." Almost all the time people will ask for some kind of evidence but still reject it and stick with their original view and it seems like nothing outside of undeniable proof staring at your face is going to change your opinion and even that's not certain, as you might still reject it because you don't want to accept it.
Evidence does make me change my mind about things: there are quite a few over the years I've been wrong about & accepted that. The last study I posted on this thread looked at autism rates of 95,000 children, both vaccinated and otherwise, and saw very slightly lower rates of autism in the vaccinated children (note that the authors didn't say "look! vaccines protect against autism", they went looking for confounding factors which might explain the correlation).
That's the sort of evidence that makes be believe things - not youtube videos (however poor the production) quoting people out of context, not people who keep trying to find something else to blame on vaccines requiring yet more studies done properly to prove them wrong, not sites like mercola or whale.to that print any old unevidence twaddle so long as it fits their conspiracy view. There have been literally hundreds of studies, probably thousands, nearly all of which show just how safe vaccines are.
Notice, however, that when a vaccine does cause a problem (a recent one that has just come to my attention:
2 babies die after vaccination in southern Mexico - CNN.com ), there is no attempt to cover up or pretend it didn't happen. They tried to work out why (probably a failure in the refrigeration - my Spanish is non-existent so it's what google translate made of this:
Falló cadena de frío en vacunas | El Economista ).
