Yeah I was just coming to say something along those lines - it's difficult to determine the true effect of the vax because we don't have proper control groups to look at - those who are healthier and have lower risk will be more inclined to self-select out of the trials, those with greater risk factors generally more likely to self-select in.

Does anyone know where there is any good quality data on the actual effects of the Vax? I think one of the red flags for me around the whole situation is that those who want to take a dispassionate look at the data seem unable to do so because they just haven't been gathered, or if they have, they haven't been made clearly visible to general public.... There's no way I would change from my current "no thanks" to a "maybe" until I get eyes on proper data that i can see have been rigourously collected and analysed...
