Waiting for Omicron

I want to give you another update on COVID. The outlook … well, it’s not good. Certainly not in the near-term. Here is a good summary of the emerging science of Omicron from Dr. Eric Topol. We now have at least ten lab studies that look at immune response to Omicron, specifically neutralization studies which broadly measure the body’s first line of defense against infection. The more studies we see the more they reinforce each other. Very limited protection against infection with a two dose mRNA regimen, though presumably still substantial protection against severe illness and death. A booster appears to get up towards the level of protection against infection two doses provided against Delta, though not quite as high. Two doses and prior infection also seems to produce fairly effective protection. Three doses and two doses plus infection seem to be in the same ballpark of protection.
