There is a flu vaccine every year. It's basically a group of scientist's best guess in that year's flu strain. The average effectiveness is 70%. The corona virus vaccine, when available, is unlikely to be different.
I have employees who make more on unemployment and unwilling to come back to work. In a way and in my mind, Hawaii is almost like those employees. Their tourism based workers are getting federal unemployment till end of July so they are fine for now. But what's the plan when that money runs out? Are they banking on a Republican administration bailing out a democratic state when the mainland states had already reopened? When they inevitably are forced to face reality and reopen, they had already missed the vast majority of the tourist season, and numerous people (me included) had been turned off by how the state handled this. I do have my trip pushed to August but I am having serious second thoughts on going even if they reopen. Given how this leadership handled the whole situation, who's to say they won't flip flop and hunt you down to impose a retroactive quarantine?
Absolutely terrible leadership.
