Most sports events are halted, suspended, postponed, and canceled because of the pandemic virus for about to 1-2 months now. Within that short period, the damage is serious so I can't imagine if it will take a year or over.
The impact of Covid-19 on sports bet was felt. Many sports bet schedules have been postponed and even canceled because of this pandemic. However, several sports bets are already planning to reopen their sports bets in June. On the contrary, many sports bets are partially retreating even at least September will open again for security. This has been an extraordinary and influential effect on many parties.
a) wait for the vaccine even it will take years, end of the discussion
I think this is very crucial, If waiting for vaccine over the years, it means that sports bet will be dying. I don't think that the sports bet will wait for years to be able to play again. they will try to open the sports bet for some reasons and with notes. Of course, it is done by paying attention to the condition. In this case, as the previous pandemic, this may end along with the condition of the human antibody to be able to against it. And I am sure that now some parties may offer the vaccine as one of the solutions for this pandemic.
b) resume slowly with several considerations such as no audience, limited number of staffs or any important things to do before considering resuming, unless the area or place was heavily affected
This might happen, but is it true without the audience? Or will this batch sport take place online or live streaming? Of course, I'm sure activists and business people in batch sports will not standstill. Especially because this is a business field for many parties. It won't be closed any longer.
