What goes up must come down, but until we have a lot more people vaccinated there’s no reason to assume that we will be done by the Fall. This wave may drop some time soon but there will be future waves until enough people are immune…the easy way with the vaccine….or the hard way. Too many people are electing the hard way. At least large corporations are now starting to step in and say enough is enough and protect their workers. This could help get us towards the “enough people are vaccinated“ goal. In polling that was done there was a not insignificant number of people who said they wouldn’t get the vaccine unless their employer or school required it. I think in a way it gives some people an out to say they didn’t “give in“ and get the shot, they got forced into it for work. I don’t care how or why as long as they take the shot.Yes there is speculation on that from reputable sources, and it's reasonable, but it's only one hypothesis among several. We don't even know the trajectory of the UK yet. It could dip and then spike again, like what happened in Jan to April. So far we see evidence of a decline in the UK, but we don't know if that will be a sustained decline or a dip before another rise or plateau.
No way to know if by the fall this ends, especially with the variable of many schools opening without masks and unvaccinated children. It might decline, I hope it does, but Delta is a very knew and unknown equation.
