This article reports that a team can predict with 83% accuracy the severity of COVID-19 by looking at three components of blood (mostly TH17, a helper T cell, and immune system cells IL-17 and IFNG).
Yesterday I referenced a preprint which said that vaccine effectiveness in kidlets was awful. Today, there’s a different report which also says it is not great. For kidlets 5-11 years old, the effectiveness against hospitalization (for undifferentiated Omicron or Delta) was 74% between 14 and 67 days. That probably drops with time — all the older kids’ VEs dropped over time — but the kidlets hadn’t been vaccinated for long enough yet to have that data.
|5–11 yrs||ER or Urgent Care||Omicron||2, <67 days||51%|
|12–15 yrs||ER or Urgent Care||Delta||2, <149 days||92%|
|12–15 yrs||ER or Urgent Care||Delta||2, >=150 days||79%|
|12–15 yrs||ER or Urgent Care||Omicron||2, <149 days||85%|

This blog post by an unpaid volunteer who has the best comprehensive vaccine info tells what she does to keep it up. Spoiler: it takes multiple hours per day.
This is a quite technical paper on fabric masks. It says that cloth masks probably aren’t as good as nonwoven ones (duh), but it also goes into a lot of the science of cloth. If you are a scientist who works with fabrics (perhaps as a craft), you might be interested in this. (Everybody else, give it a pass.)
