So you really think it's safe not to have control groups? What kind of science is that?

Of course not - new vaccines obviously go through rigorous clinical testing before being allowed on the market. This would include use of all appropriate clinical processes, including controls.

My point to you before was only to show that the efficacy of vaccination as a tool for the prevention of certain diseases is proven, utterly and completely, by the literal eradication of several terrible diseases in the real world. And, during the process of those diseases being eliminated by use of vaccination, there were portions of the population on earth who did not get the vaccinations first and who therefore became a point of reference to compare the efficacy of the vaccines in the real world.

Temporary control groups that is, we need to know what the difference is over generations.

But we've had vaccinations for generations already - and the overwhelming majority of people who have been vaccinated experience no negative effects, either short, mid or long term.

There are several myths about vaccines causing various disorders or diseases - primarily autism - but they have been debunked.: and here: and here

But, let me plays devils advocate for a moment. Let's say that tomorrow it was proven that vaccines did in fact increase the overall incidence of autism in children. The alternative is that smallpox and polio still exist - or that measles, and whooping cough still kill infants and toddlers - not to mention the wide variety of diseases rarely seen anymore thanks to widespread vaccination.

But as I've said, autism is not caused by vaccines - nor are almost any major maladies in the great majority of people.

We don't know what the effects are unless we have something to compare to. I could care less if vaccines or aspirins are making people genitals fall off, I'm not saying that vaccines are dangerous or that we'd be better off without. I'm just saying that we don't know, that without those long term studies we don't really know the impact they have. I am saying that it's dishonest to say science has settled what vaccines do because we are not studying groups of people going without vaccines over many generations. No control group no experiment, simple as that.

Can't you compare it to before these vaccines came to be? Like when people were glad that their children made it through childhood? Or when life expectancy was way shorter? I can't tell if you're trolling or if you are serious. This isn't worth your time @dber.
