This is why I get so frustrated with people justifying continued shutdowns "until it's cured by the vaccine". Almost every highly contagious virus mutates quickly. Same with bacteria. The cat is already out of the bag, even if we do manage to completely eradicate it it'll take years. (To be clear I'm not against virus control measures, I'm just frustrated with the flawed reasoning that all this will just go away when the vaccine is within reach. It couldn't be easier to get a flu shot and yet we'll probably be dealing with the flu long into the future. If we know this will stretch into say 2022 I have to imagine that will change a lot of peoples attitudes as to how society should react)
