I have no medical training or medical knowledge whatsoever. So can someone explain to me why we've had the flu virus for 100 years plus and never developed a vaccine but we have had this Covid-19 for only two years and have vaccines coming out of our ears (so to speak)?
You are misinformed. People vaccinate against various flu virus strains, every year. That's what a flu shot is.
