Your looking for arguments if your arguing with what I said. I said the vaccine immunity wanes, same with natural immunity which is why I said if someone was vaccinated early or infected early they should get another dose.
I think natural immunity isn’t factored in because for most people it’s harder to prove, however I’d be for including it for these restrictions/requirements if someone has a positive test and can actually provide results.
Neither the vaccine or prior infection stop people from getting the virus, however they both help prevent it.
Which one is more effective is probably too early to definitively say and likely depends on the strain someone had initially/their viral load/etc.
I wouldn’t say it’s misleading to have people get the vaccine if they’ve already had the virus. It still bolsters immunity.
