I just remembered something else - I also feel sorry for the majority of school and uni students who are likely to have to repeat the grade next year, as the schools won't reopen this year once they close... because no one is going to be brave enough to re-open the schools before the vaccine is ready.
A lot of schools and Unis may have set up online learning, but a lot of kids who don't have computers, or probably won't be able to afford monthly internet fees, won't be able to keep up with those who can do their schooling from home... and that's IF those kids have the self-discipline to commit to school studies for several hours a day at home without the risk of detention or some other school penalty, particularly if they are in the higher grades and their parent(s) still work, leaving them home all day on their own.
