Recovering from covid is the best vaccine that currently exists. It is the only thing that acts remotely like an actual vaccine. Omicron clearly blew through the immunity people developed from cases of Alpha, Beta, and Delta, however, so even recovery-induced immunity depends on the evolution of the virus. That said, the covid recovered (particularly omicron-recovered) are the people who can be most closely considered "vaccinated" at this point. This is true with zero relation to jab-status. Those un-jabbed who have recovered from omicron are every bit as safe as those jabbed who have recovered from omicron.
