I guess we are not done yet as a mutated form of the corona virus just showed up in the UK and the Netherlands, and it was not unexpected as viruses will mutate, and I would not be surprised if sooner or later it will show up here in the US as well. Will the vaccine just developed for the current strain of the corona virus also work for the mutated form? It will be interesting to see and revealing what reaction a person will have who just has been vaccinated for the current strain and encounters the mutated form, perhaps now or a year from now?
