The one constant in all reporting and discussion about potential SARS-CoV-2 vaccines is wishful thinking. I don't blame the pharma execs for that; talking up their stocks is their job. Everyone else, though, could do with a great deal more skepticism. We'll be lucky to have a commonly-available, somewhat-effective vaccine next year. If you had listened to the cheerleaders in June, you would be shocked to learn we don't have multiple such vaccines now. Regular mask wearing and careful avoidance of problematic public situations is already more effective than any vaccine for this virus will ever be.
