The safety protocols have been deemed satisfactory. You overestimate the risk. New variants are created all the time by natural transmission. Including the recombination of two different strains. So the controlled, artificial recombination is like a grain of sand in a bucket of sand. And even if it "escapes", the escaped variant would still have to evolve and prove itself. Experts don't see this as a risk.
