You don’t need, and in fact lose validity, using entire countries as control groups

Obviously, but you need people to be not vaccinated. But it still is the only way to sensibly differentiate effects of Covid and the vaccine itself if the spike protein causes damage.

I don't believe that we empirically know the positives either and it is the only way to reliably test. There is no alternative to this and it should have been done before any mandates came up in my opinion.

There are already studies comparing the mortality risk of those who got the vaccines against those who didn't, among only people who didn't get COVID. If you're worried about the vaccines, just take them 8 weeks apart instead of 3, and/or take an ACE inhibitor first to up-regulate your ACE2 receptors.

I have already takes 3 doses. These studies are insufficient and have to be conducted long term. It is about isolating the effects of the components. I don't think it is disputed that the vaccines did not have the expected safety profile. Further research will give us a clearer answers.

China data (if possible to obtained) could be used as a datapoint, as a country that is highly vaccinated but not with MRNA vaccines.
