This study neatly explains everything we are seeing.

- Why a number of elderly folks aren't getting hit despite being probably fairly low on Vitamin-D: Due to existing T-cell immunity they acquired when they were much younger (and had more Vitamin-D to activate T-cells)

- Why there is a correlation of COVID with Vit-D deficiency even after age-adjusting: People with low-D did not develop strong T-cell immunity, hence more vulnerable.

- Why the infections and deaths are now fairly low in retirement homes: because they already went through a nasty first wave and if you didn't die you either had T-cell immunity or you did get sick developed it. Having received the vax may not have done all that much extra.

- Why there was a major rise in cases in tandem with vaccination rollout in pretty much every country that started vaxxing: the folks with single vaccination dose but NO T-cell immunity suddenly became a lot more vulnerable. Since they were vaxxed during a pandemic the inevitable happened and they got horse****ed.

There has been an interesting lack of data regarding COVID deaths after only one dose of vax, outside of retirement homes. I'm guessing governments are hiding this data because it is not very flattering. The chart out of Hungary was only for people who got both shots.
