Currently nothing is done to incentivize people to stay Covid free.... just the fear ... but even that is not enough. (Most young people think Covid only kills older people, so they just ignore the rules to stay safe)
Do we really deserve an incentives for taking care of ourselves to not get infected? I mean its our responsibility to comply and be healthy for our own sake, thus I think its not necessary.
Besides there are many institutions specially the health care facilities that really need funds to enhance their services and accomodate more patients. In our country we are lacking of health care providers and hospitals, the reason why some patients are not able to survive for not getting the treatment they needed.
So instead of giving a reward for the covid free people, why not think of more essential things that need the budget first to address the main issue that we currently face.
Yes instead of incentives they should give things that can avoid someone to caught covid or if not just to decrease the chance of acquiring one. Like you said it is our own responsibility to protect ourselves and the government could make some law to those who don't abide from the rules.
