Covid isn't going anywhere. It'll be much like the flu going forward. Something that's around all year but really peaks (at least in the Northern US) during the winter months and something for which we'll need to get an annual shot. Hopefully the wave we're about to get hit with will be the last major one.
I'm all for the NFL promoting the vaccines, but there is no way we're keeping it substantially out of the locker rooms unless all the players and coaches are forced to quarantine on their off days, which is not a viable long-term policy. But even with the Browns, the reporting suggests that most of the positive cases were asymptomatic, which means the vaccines are working. They're doing their job. That's good news.
