I think the big questions remains if science can out pace viruses and bacteria progression. I believe our own immune systems are the most rounded long term defense. Health care leaders and governments should promote 1) get healthy, 2) distance 3) mask if you can’t distance in crowds 4) get vaccinated when you can. That said I worry that chasing viruses with vaccines will lull people into thinking they can wait until they are sick and take drugs. Speaking of drugs ivermectin should be created in every country and made available but I wonder again if it will lower our own built in defense system over time?
