it seems to me that there is still an age above which generalized vaccination should be advised systematically, right?
on what basis should the age limits be defined?
Well, we are not at all competent. It's like determining when to recommend breast cancer screening by mammography, it's completely beyond our reach. Recommended, of course. Completely agree: this is public health policy. Not imposed.
this is not already the case for certain health professions, excluding covid?
Yes, but it is quite limited and above all targeted according to the profession. See :
https://www.legifrance.gouv.fr/codes/id ... 006171171/For a practical example, I am a hospital administrator. I am therefore obliged to be vaccinated (COVID), although I am not in contact with patients.
To know also that these provisions are not to my knowledge specially controlled, they exist I think as a preventive measure for the establishments (for example, on CDD or interim, nobody ever checks the updates or not of the vaccines of these caregivers and I even think that among the permanent it's the same.)
that should be the case for all molecules, of course, but there are already studies on it, right? how was the treatment with corticosteroids handled?
Well ... it seems not. This is the thesis defended by some of the forums and the IHU and Mister Raoult (but not only him, though, we have seen other doctors talk about it), it is that a real serious study, carried out with quite large groups with relevant dosages, that does not has not been done (a priori nowhere, but especially in France where we have the means). There are even tests that were underway in 2020 that were stopped before the end of the tests. I did not look for myself, please note. But I would hardly see all these people defending this kind of thesis if it had really been done seriously elsewhere with negative results.
