While the science could change (or at least our understanding of it), why would you go this route if doctors are currently recommending to get the vaccine even if you were infected?
Those thinking they know better and have "benefit of waiting" are basically saying they have a better understanding of the virus and vaccines and immunity than the consensus of infectious disease doctors that are saying you should still get the vaccine even if you had the infection.
They wouldn't recommend that at this point if there wasn't good reason to, thought it would be harmful, or thought there wasn't any benefit.
Thinking that waiting is "ok" despite medical advice to not wait is part of the problem that we are currently in where so many aren't following the advice of those that have the expertise to offer that advice.
