Maybe the vaccine turns out to be one that is only given to older people - or maybe people will need a booster shot when they're older.
But I do think, based on the stats and information we now have, that the approach to Covid 19 will change. Eg. I don't think schools will be completely closed again, but procedures will change and we might see a blend of remote and on - site learning.
One thing that does bother me in all of this, is the people who find ways to take advantage. Eg. they are 'isolating at their cabin' and require 6 weeks worth of school work for their child.
