You're on a site centered around technology and don't seem to acknowledge the scientific process... You cannot, with 100% accuracy, model a virus that is mutating in a population that includes the entire planet. We have things we know worked in the past, we try them, and we then modify our next move based on the results. We don't say "well we got that one wrong so now we're just not going to try anything". If every scientist took the approach you're suggesting we'd still be eating raw meat and living in caves.
