@TC215 - Prayers sent for your brother's recovery.
Can anyone comment on this:

I've seen various numbers thrown around, sometimes on reputable sites, sometimes not. Between 50-92% a couple weeks after the first dose. It seems like a lot of those numbers are dated back to the first of the year, though. The WHO's official, current, stance being 92% 14 days later is interesting.How efficacious is the vaccine?
The Moderna vaccine has been shown to have an efficacy of approximately 92 per cent in protecting against COVID-19, starting 14 days after the first dose.
Everything I've read said that the Moderna and Pfizer vaccines were >90 percent effective 14 days after second dose. The numbers I most often have seen are that they are 92-95 percent effective. The information sheet I received from Kaiser Permanente with my vaccine says that Pfizer is 95 percent effective, and Moderna is 94 percent effective. That seems pretty consistent to me.
The J&J numbers are a bit more nuanced. IIRC, the J&J is ~67 percent effective against getting COVID, but is >90 percent effective against serious effects. My data sheet from Kaiser says that J&J is "93 percent effective with COVID-linked hospitalizations."
Right. I think the final numbers, 2 weeks after the 2nd dose, have been pretty stable.
The unknown variable so far is how much of that protection is there 2 weeks after the first dose. A lot is up in the air, like how long immunity from the first dose would last without the 2nd/booster, etc. But seeing the WHO say you're getting most (nearly all) of the benefit as early as 2 weeks after the first dose seems like some good news.
That's not to say people should skip the 2nd dose.
