We will need to check how does the virus react in winter and does it have any significance in increasing the cases further. If that is the case again then the cases would rise further manifolds time, and this would not be the ideal unless by that time vaccine is in place and started to reduce the cases significantly. As time passes without anything on vaccine things will start looking bleak.
I guess you don't know about the weather impact on COVID-19. It has already been established sometime back that Corona thrives in cold conditions while hot conditions tend to eliminate it pretty quickly.
This is probably why Africa has a negligible amount of cases so far. Coming to the vaccine, the earliest they could be available is in 2021 and it would reach the masses probably by the end of 2021.
We will have to continue fighting this virus probably for another year from now.
