The initial scare of COVID was that no one had natural immunity and there were no vaccines/shots available.

But even this was not true, as a substantial fraction of people harbor pre-existing T cell immunity to sars-cov-2 gained as a consequence of exposure to the myriad coronaviruses that have existed in the environment for thousands of years. We knew this in July 2020.
