Because herd immunity works on the basis that you are vaccinated (and so can't be infected) or that having had it, you are again unable to be reinfected and transmit it so the virus has no hosts to infect.So what' is not being understood?
Herd immunity is what keeps most viruses at a relatively low level! Only a minority actually have vaccines.
We don't have a vaccine and, AFAIK, it is not proven that having had Covid, you can't be reinfected.
