David, bless your soul, we were having a reasonable discussion and then you arrived.
Show me a study where the efficacy of Covid vaccines is higher than the flu shot. The flu shot is always 50-60% efficacy. Covid started higher but continually drops. That is because the spike protein is a very narrow, focused attack that went after the original virus. Two, three variants later, and the original mRNA is declining. Boosters may help, but positive tests keep on coming with vaxxed folks, so the optics are not good.
In the meantime, Anthony, people who have had Covid have a broader immunity, not less, and broader protection.
NIH - “a durable, lasting immunity”
[Link: nih.gov]BBC - natural immunity matters, and add an injection might give you “super-immunity”

Merry Christmas and a healthy and successful New Year!
