P.S., you answered none of my quite reasonable questions.
Cold is so easy to avoid, there is no need for a vaccine.
Very few people die from common cold. Big pharma is not going spend Billions developing a vaccine nobody will pay dollars to get. Simple economics.
Also cold does not destroy your lungs, heart, liver like the covid-19 virus does. Only thing common between the 2 viruses is both have corona on surface.
