And just to make things even worse...There's a possibility we will NEVER have a working vaccine, meaning this is permanent.
After 18 years of work we have no vaccine for sars, which Is closely related to C19. We have no vaccine for HIV despite decades of trying.
If we never get a vaccine we will have to change the way we live. This social distancing and lockdown cannot continue, if this goes on for years, and without a vaccine it will, there has to come a point where the crusade is abandoned and the virus will run its course and kill hundreds of thousands every year, it will just become something we have to accept like heart disease and cancer, we can only do so much to prevent and curtail these conditions but we can't avoid them completely. COVID19 might become something similar for a long time if not forever
