Of course it's possible. The real question is how likely is it that at least one strain of regular flu is bioengineered ad released by "the same people?" I remember a time when the only flu variant was flu. There was no flu-A and flu-B. I'm only 45, so it wasn't that long ago. Seems to me that right around the time flu "vaccinations" started to wane, SARS-CoV/2 was released.
