I really can't respond to this properly without getting way too political so I'll just address this next bit
This statement made some sense when the vaccines were first rolled out. It makes zero sense now.
Since they were first introduced BILLIONS of initial doses and boosters have been given. Covid deaths and hospitalizations are way down from their peak rates. My understanding is that side effects or adverse reactions are rare and in line with any other vaccine or medication. And the vaccine has allowed life and society to pretty much go 'back to normal'
So, when you say "till I know more" what exactly do you mean by that? What specific information do you need that you don't already have?
