A few nice papers released today: One on Vitamin D, but a more interesting one on T-cell immunity to corona viruses. The researchers looked at T-cell activation (a form of immunity) in people who had SARS-COV1, people who had SARS-COV2, and people who had no exposure to either one.

1) People who were exposed and recovered from SARS-COV1 STILL had t-cell activation! That's 17 years! Hooray!

2) People who had SARS-COV2 and recovered all had T-cell activation, even though their antibody levels had faded.

3) Some people with no exposure had t-cell activation to SARS-COV2. They hypothesized that was because their T-cells were activated by one of the other four corona viruses that circulate as common colds. They looked at the RNA sequence for various corona virus proteins the T-cells reacted against and found a huge amount of commonality among all seven known corona viruses. (The three bad ones and the four innocuous ones.)

So my hypothesis about kids being mostly immune because they had colds in the past, has some real science behind it now. (And before you throw cold water on the 17 year immunity, their test was against unique SARS-COV1 proteins.)

Nice interview on Youtube: Dr. Bean with Dr. Pauld Marick. (inventer of the MATH+ Protocol.) Very informative. He explained that hydroxychloroquine is completely taken up by the red blood cells and then leaked very slowly back into the plasma. It takes a very long time to get your plasma level up, which is why it's only useful if you take it at the very first sign of the infection. He also said that most of the HCQ studies so far seemed to be designed to make sure it didn't work or to actually kill patients! You don't hear the head of a service at a major medical school say that very often.
