Natural infection induced immunity is bound to be better than the vaccine . So those who have recovered from covid , may be they can skip the vaccine? Especially in countries where there is vaccine shortage ?

Yet, almost all hospitalized and deaths from Delta right now are unvaccinated people. Would be good to know what percentage of those had already been infected with COVID once before.
