They are definitely predicting another wave in late summer/autumn. I'm not clear why.
I am not sure either. But there are various issues.
Not absolutely everyone from vulnerable groups is getting vaccinated.
Some residual risk remains even after vaccination, especially for vulnerable individuals. We are still amassing data on this, there are various figures emerging.
At some point, we may see the benefit of vaccination wear off a bit possibly, we will still be getting data on that too as the months go by.
New variants are likely to emerge, it isn't clear how much of a problem that will be. We are however hearing of tweaked vaccines for the autumn and that would be to avoid another wave.
The autumn and winter are generally times when respiratory viruses are more of a problem.
If people mix in big crowds over the summer there might I suppose be some spread from that, less so if outdoors hopefully.
I can also imagine that some intrepid souls might make it overseas and come back with some souvenirs.
Wouldn't it be great though if none of this happens and it all just floats away?
