Doesn't make sense. We already had non-herd immunity producing vaccines for flu. That covid vaccines produce the same outcome isn't a particularly special case.

Doesn't make sense. We already had non-herd immunity producing vaccines for flu. That covid vaccines produce the same outcome isn't a particularly special case. It's not even that complex to understand the WHY they don't produce herd immunity. I can understand being frustrated because herd immunity was touted as a possible benefit of mass covid vaccination, but that has nothing to do with whether it exists in general.
