What is an influence on our health that is proving especially useful for quickening the pace by which we are adapting to and developing protections against COVID-19 is? Behaviors? Heredity? Technology? Environment?

I'm not an expert on this but I would suggest behaviour and technology, at least in the long run, are our best weapons against Covid 19. Behaviour like isolatiing, not travelling, wearing maskes, social distancing are all effective in keeping the numbers down. Effective vaccines are being released on the tech side.
