They already are saying there are 2 different covid strains in the US. There will be vaccines, but I can see where like the Flu virus, The vaccines will not be effective on all the covid strainsI think we need to remember that this is just TEMPORARY! IT is not like scientists and doctors don't know what to do it will just take time as in 12 to 18 months MAX...once a vaccine is in place and hospitals have preparations in place and treatment options improve this will be just like the flu and if it does not mutate it won't even be a blip on the radar in a few years. The reason everything is crazy right now is because it is "novel" which means "new" we don't have a vaccine or know what proper treatment looks like.....BREATH, EXHALE....it will be OK.
