We had the chance to do that with the lockdown, we didn't did we.We need to look at fixing this as a long term solution, a vaccine is just covering up the issue (I'm not anti vaccine). Did anyone see the Attenborough show? Climate change is partly to blame for pandemics spreading. Human life as we know it needs to change to fix this.
I also can't see the link between climate change and a virus. There have always been diseases and viruses, over population, lack of running water, adequate sanitation and poverty, there's your spread.
Cholera was dirty water.
