I'm fully vaccinated and have received my booster as well.
With that said, I think the NBA has been very proactive in dealing with COVID. As a matter of fact I use it as sort of a model as how to track and live with the virus. Everything thing they have done thus far has been very well thought out based on science.
IMO, where we are now, is how to live with the virus. They are not saying health and safety protocols shouldn't be taken if symptomatic or not to mask or social distance in the community.
In a way, the NBA has created a bubble of vaccinated players and personnel.
On September 30th, 2021 at least 95% of the players were in the vaccination process. I can only imagine it is much higher now.
Nearly half of the league's teams have said in recent days that they are already fully vaccinated or on the cusp of hitting that threshold.
