To continue this... I don't think the flu vaccine is nearly 90% effective. I am pretty sure the flu vaccines hover around 60-70% effective. A 90% effective vaccine would stop the spread drastically to the point where it might just stop it wholesale. in addition the virus envelope is so fragile that it won't stay in the environment for more than a few days compared to something like the norovirus that can last for a long time on surfaces(iirc) because of a lack of a fragile lipid enclosure.
