That doesn't make sense. A major discussion in the public since Covid caught on was about herd immunity -- and that infection would drive some of this. Maybe the concern is that we aren't inclusive of natural immunity in our policies. But that is purely an issue of bureaucratic process (for example, there should be no false positives in administering a vaccine) and incentives (we don't want people to try to get infected since infected people can transmit the virus), not any statement about the science related to natural immunity.
