Put on Covid list
NFL will be requiring boosters within the next week or so. Will that help?[sm=shrug.gif]
...
Boosters will help, probably 7-10 days after they are given. For most players, the boost will keep antibodies high through the Super Bowl.
As a rough sketch: Delta often starts as an upper respiratory tract infection. If the person is vaccinated or previously had a case, the B-cells start regenerating antibodies, and usually that stops the virus before it infects the lungs, or worse becomes a systemic infection.
For months after a boost, the immune system has a big head start: antibodies are high and a lung/systemic infection is much less likely. But eventually the T-cells and antibodies wane and the B-cells remain (for SARS, we know they're still active 17+ years later). Against a slower virus, maybe the immune system could respond fast enough to prevent an infection, but Delta takes 2-3 days to be transmissible. It's extraordinarily fast. That speed is why we'll likely need regular boosters.
But we shouldn't be surprised the Vikes are getting hit with COVID. They had a relatively low vaccination rate, and Minnesota's cases surged when the weather got colder, which pushed people indoors and closed windows.
I mistakenly thought that Delta had peaked in MN a few weeks ago when cases fell off. I expect that we'll get a post-Thanksgiving surge, and then cases will fall rapidly and Christmas might be pretty normal. Kinda depends on how many more people get vaxed, which should get a bump up now that 5-11 are now eligible (not much immediate personal benefit for the kids: they're super-low risk. But still, the vaccine is much safer than getting COVID, it'd make them less susceptible later in life, and it'd be a substantial societal benefit).
