You have to wonder what the "herd immunity through natural infection" crowd will say if a 90% effective vaccine is released within months
Efficacy varies between vaccines, but preventing 90% of disease is definitely high enough. The real question now (if those results hold) is how long does that protection last and whether it protects against severe disease
