Not all vaccine have the same efficacy.
The same applies also with Adverse Events. (e.g. in Italy they are not using AZ for "younger" people").
because this depends from age/sex/previous medical condition.
Here there is an example of such data (efficacy) with comparison also for 1 or 2 shots.
https://www.bmj.com/content/373/bmj.n1088Other data have been published during this months. Data from trials have been confirmed so nothing less or more then expected...
Efficacy can't be pooled easily, and it's impossible have the same result for all age/sex/health condition etc.
In early stages of vaccination, I remember quotes in media that most common vaccines used in Europe (Pfizer, Astra Zeneca, Moderna, Johnson) is somewhere 90% effective. Yeah, it can't fully protect you from infection, but helps to avoid serious forms of disease. But considering everything, number of fully vaccinated people deaths is too big IMO. Yes, most people die had other serious diseases like cancer which didn't let to make immunity, but still.
And I don't like conspiracy theories, but number of strange deaths when relatively young healthy people die without any obvious reason looks big in my country. Every day we have at least several such deaths reported. There always were such deaths, but not so many. Or maybe just nobody paid attention to such deaths in past...
