> It wasn't economical to develop those. It was, if you run the numbers. There's over a billion of cases of common cold in the US alone every year, people have it 3-6 times a year, every year. The economic loss is insane. If you want to target just the coronaviruses for starters, 20% of common cold is caused by them. People with comorbidities and weak immune systems die from common cold too. And yet we don't have a vaccine. Nor do we have a vaccine against HIV for example. Vaccines are hard to do for some things, and C19 could easily be one of such things. What I find especially pernicious is that people don't realize that it's _not going away_, ever. It's going to be seasonal now.
