But you are wrong in that the body doesn't maintain immunity to coronaviruses very long. You've probably been infected by the same cold coronavirus a dozen times or more in your life.
Immunity varies from a few months to many dozens of years depending on what the specific virus actually is (i.e. coronaviruses vs chicken pox for example).
Current research indicates lifelong immunity to sars-Cov-2 after natural infection as the b and tcell antibody mechanisms move into the bone marrow and just keep pumping away.
And people naturally infected with SARS-COV-1, from the SARS outbreak, are still showing immunity to that virus (close to 20 years later). COV-2 is extremely closely related to COV-1 and it would be logical to extrapolate that the immunity lengths are going to be similar. At least more logical than looking at the cold virus immunity and extrapolating from that.
You don't need the vaccine period.

Correct on all accounts.
