An article just appeared in the New York Times regarding moves by the EU to allow vaccinated travelers into to Europe as early as this summer. I've pasted the link below, but I'm not sure if those without a NYT subscription can open it. It's the first indication I've seen that makes me just slightly optimistic that travel to Europe my actually be possible later this year, although that doesn't mean I would go for it. But it's nice to think it could be an option . . . if we human beings play our cards right . . . and if "vaccine hesitancy" doesn't derail our scientific progress.
