ORIGINAL: Mister Ed Reports are it is Dozier who is in the hospital Put on Covid list NFL will be requiring boosters within the next week or so. Will that help? ... 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).
