I agree with you, the Pfizer is probably slightly less lethal than the moderna, and the AZ is probably killing at least 2x as many people. My dad got both moderna jabs. I strongly discouraged him. In his 80s and he’s still alive so far. He said he felt fine, no problems. But a few weeks later he complained that he was getting more winded than usual and also he started losing bladder control. I didn’t immediately link this with the vax because he’s old. But I eventually concluded that the breathlessness was probably mild myocarditis and the incontinence was a symptom of transverse myalitis, both common effects of the vax. These symptoms went away after a couple months. But other frail people could have heart attacks which are never directly linked to the vaccine.
