There's tons on science talking about the immune system response from a covid infection. From what I've seen the protection conferred from the immune system response to the virus is at least as good as vaccine immunity and perhaps better, given that it is a more broad based immune system response not targeting just the spike protein like the vaccines.

I don't understand your comment. We were talking about herd immunity at the moment, and that natural immunity and not just vaccine immunity counts towards that.

Why did you bring up cowardly? Is that in reference to the woman who had to be hospitalized for anaphylactic shock after her first vaccination?
