These facts don't necessarily support vaccine mandates from a moral POV, but they're still the facts and by ignoring these facts you're the one spreading nonsense.
The vaccines reduce contraction, transmission and severity
It just means the vaccines we have don’t reduce transmission by 100% and you have a disease that is highly infectious. Just because a medical intervention doesn’t work 100% of the time doesn’t mean it’s 0% effective. Most interventions (vaccines, drugs, procedures, surgeries) don’t work at 100.0%.
From the data I’ve seen it appears the mRNA vaccines have some effect in reducing transmission while the other vaccines don’t. It is correct to say that the efficacy against transmission has dropped significantly, but that doesn’t mean it’s 0%.
