I think the major reason that different governments are opening the system including sports and soccer is because the reality is that covid-19 is not being eradicated anytime soon and so life has to start again with living with it.
It's difficult to think that all industries will wait for that vaccine before considering resuming or re-opening as what I also trying to point out on one of my created threads here.
Even the vaccine will be made, expect several months after the successful creation before it can be available to all countries as it's not easy to reproduce and distribute. While waiting for the vaccine, which is currently on progress, it's good to go back to business while following the safety health guidelines. We should not allow the virus to just freeze all business.
As for betting, no changes at all. We can still bet online even in the new normal just like we always did before.
Talking about betting, you didn't have live soccer to bet on especially from European country leagues while the lockdown was on as you know. You could only bet on visual soccer
