My second point—also disputed:

"Today's 'break-throughs' are milder in effects".

Answer:

Post-vaccination infections, or breakthroughs, might occasionally turn symptomatic, but they aren’t shameful or aberrant. They also aren’t proof that the shots are failing. These cases are, on average, gentler and less symptomatic; faster-resolving, with less virus lingering—and, it appears, less likely to pass the pathogen on.
