I agree that the vaccines pose very little risk to a given individual, even though the possibility of long-term effects have yet to be ruled-out in the scientific literature.
But there are selective pressures & second order effects to consider regarding mass vaccination using the current mRNA vaccines which induce an immune response that is highly targeted towards the SARS-CoV-2 spike protein [1][2].
Combined with the evidence that people who have naturally acquired immunity are protected equally as well as vaccinated individuals [3][4], and that combinations of existing medicines have proven effective in reducing hospitalization and death [5] - don't you think that a strategy focused on vaccinating only the most vulnerable populations across the world would be more rational?
