Absolutely. An infectious diseases expert said last night on the tv that the best we can possibly hope for is a vaccine (most likely from either the US or UK) to be proven by November/December. By the time we can manufacture a couple of billion doses it will be December, 2021. By then the virus will have had ample time to mutate.Which is one of the biggest concerns - that we end up fighting something that's worse than we currently are dealing with.
We are continually in catch-up mode. There is no guarantee that a vaccine, even if found, will be effective in the long term. We could have anual Corona virus outbreaks as it mutates like the normal flu.
