The discourse has become politicized, unfortunately, and for whatever reasons the voices of the pro-vaccine faction in the U.S. have become dominated by people who reflexively discount the science. This doesn't seem to be the case in Europe, where the EU-wide immunity passport treats those with prior documented infection the same as the fully vaccinated. This was pointed out to me on HN a few weeks ago, when I opined that it would be logistically impractical to verify and issue immunity passports to the previously infected.
Would it be better if those with a previous infection received a vaccine? Maybe. That's a more complex question. But at this juncture that's moving the goal posts; it's scientifically and politically unreasonable to make that demand.
