Vaccines

This study (in the US) found that for counties with vaccination rates above 40%, for each percentage increase in vaccination rate, the COVID-19 case incidence dropped by 1.5% and the death incidence dropped by 2.7%. Go vaccines!


I prefer to wait until things are done-done before publishing about them, but this is important: anonymous sources say that Health Canada is going to approve Pfizer for kidlets on Friday!


This preprint reports on a randomized controlled study with four arms: placebo, Novavax’ COVID-19 shot, Novavax’ COVID-19 shot plus an influenza shot at the same time, and influenza vax plus placebo at the same time. The COVID-19 vaccine effectiveness dropped only slightly (from 89·8% to 87·5%). There were slightly more side effects with two shots than with just one; there was no difference in influenza effectiveness between with and without a COVID-19 shot.

Mitigation Measures

I prefer to wait until things are done-done before publishing about them, but this is important: anonymous sources say that the Government of Canada is going to drop the requirement to get a PCR test to re-enter Canada if you have been out of the country for under 72 hours!


This meta-analysis preprint found that that mask-wearing and hand-washing each reduced COVID-19 risk by 53%, and physical distancing dropped risk by 25%. I was quite surprised that handwashing and mask-wearing had the same benefit.
