Sure, you could choose to believe the wild conspiracy theory that a virus kindly waited for us to be ready to create a vaccine for it before it jumped to humans, out of all of human history. Or you can believe a vastly more probable explanation: correlation due to common cause. Humans have been paying particular attention in the past decade to this spike protein; some of this research led to a vaccine, while another branch of research led to a lab escape. The conspiracy theory of "luck" and kind viruses doesn't even pass the laugh test in comparison.
