Actually Aly, I didn't outline anything. I said I thought it was possible that vaccines may trigger autism in certain susceptible individuals and you went off on a big tangent trying to prove that a population study can show individual risk and (somehow) identify susceptible individuals.
The larger the sample size, the less likely that you are going to be able to determine anything about a small subset of that sample. Surely that's obvious? Needle in a haystack analogy? No? 
Still don't have those studies looking at vac vs unvac in a group of susceptible individuals. Population studies aren't looking at susceptible individuals.
"you clearly think vaccination risk is too high for "susceptible individuals""
Hold on. I thought you agreed with this as well? Didn't you agree that there are "Medical reasons to not vaccinate"? My point was simply that we haven't identified all these 'medical reasons' yet and we should be continuing to try to do so. That's how safety can be improved. In order to do that, you have to actually acknowledge that the reactions can occur, take them seriously when a parent reports them, record them and investigate them.
I'm not focussing on figures at all. You brought them up and used them for hypothetical calculations. I just produced more relevant ones from the vaccine we use in the UK.
The conversation hasn't been about trying to avoid every tiny risk. (Did you think it was?). It was (among other things) pointing out that you aren't in a position to say that someone has made the wrong decision for their child. You don't know whether they have or not.
(It was also correcting some misinformation about various diseases/likelihood of contracting tetanus etc.)
"yes, and if we were looking for a link between peanuts and allergic reactions and didn't know one already existed, they would be a bloody excellent way to find out."
I can't believe you still don't get this after all these pages and pages of posts. If you were trying to find out something about just the peanut allergy sufferers would you use a population study? All you want information on is the peanut allergy sufferers - just them, no one else. Population study is still the 'gold standard' for that in your opinion?
