The fact that the group of participants in the study was of a certain age range means that the study says nothing about the result for people outside of that age range.
Much more and better explanation about flu shots here:
That's exactly what I'm saying. The study tells me something about that age range, and nothing about anyone else. So it tells me that it's a good idea to get a flu shot when you reach that age range. What exactly are you trying to say???
> So it tells me that it's a good idea to get a flu shot when you reach that age range.
No, that's not what it tells you. Really, I can't help you if an article that spells this stuff out in great detail results in a response that indicates that you have not understood it, they spent a lot more time on this than I will be able to do in this context.
... The study subjects were in that age range, were they not? I truly don't understand how you could draw conclusions about how a young person should approach flu shots from this study, and I'm not approaching this from a malicious place. If you're not going to converse in good faith, this is probably not the place for you.
Not anti vax, not that it should matter for this argument.
This tells me, when I'm 65, I should definitely be getting flu shots.
