Given the number of anti-maskers and anti-vaxxers, I prefer to take a more cautious approach as I've developed a pretty low opinion of the U.S. populace's ability for self control to benefit others. With the lack of vaccine documentation I'm expecting we'll get some bad outcomes in regions with poor self control. But we are seeing ancouraging signs around the benefit the vaccine is having and the risks to or from those who have been vaccinated.
The recent experience of the Yankees in which 8 members, all vaccinated, tested positive is a case in point. 7 of those 8 were asymptomatic. I'm not sure if those 8 posed an equivalent risk at passing on COVID as someone w/o the vaccine. But it points to ongoing risks to those w/o the vaccine and suggests, to me, some caution at just dropping masks or other social distancing quite yet. Things are heading in the right direction, however.
