That’s WAY too precise, if he doesn’t care to sound like he knows it’s being designed.
Well, coronaviruses have been studied a lot so they mutate at a fairly predictable rate. And we certainly can pinpoint when the vaccines started being heavily administered. So if you are hypothesizing that, subsequent to the vaccination program, it will take only a certain number of mutations before the virus evades immunity, then it doesn’t seem that making a ballpark estimate would be too difficult.

Has nothing to do with designed vs natural origin. It is a mathematical calculation based on intimate knowledge of viruses and the manner in which they evolve and spread. The size of the population involved and the time it takes to do so, modified by the evolutionary pressures present or absent are all considerations.
But you went for the cheap shot because you have no idea what is involved at all.
