Herd immunity is not a fixed vaccination percentage pulled from Anthony Fauci’s latest media appearance. It’s the immunity level at which cases stabilize and begin to decline. It is defined by observation.

Cases are at all-time lows in the most vaccinated locations, and are dropping rapidly nationwide.

No, it's the level at which people not eligible for vaccination are no longer at risk because most of their peers are incapable of spreading the disease. The political aspects are just some stuff some people made up.

No, it’s a scientific term. It has a definition. Not just something you’ve made up based on your feelings.

Herd immunity is when Rt = 1, or 1 - 1/R0

It is the point when infections begin to decline due to acquired immunity.
