Mitigation Measures This article says that masking was responsible for a 68% reduction in transmissions and that regular testing got the reduction up to 77%. This preprint looked at different mitigation measures in schools in Switzerland. Some highlights of the reductions in viral dosage they saw: Keeping all the windows open in winter: 14x Universal… Continue reading 2021-08-20 General

Vaccines I see a lot of anxiety about vaccines decreasing in effectiveness. In the US, Biden announced that third-dose-boosters would start being delivered on 20 August, never mind that the FDA has not yet approved boosters. Here is an example of someone showing the waning effectiveness of the vaccines: But some of the studies have… Continue reading 2021-08-19 General

The BC modelling group has released another report, which says we are fucked if we don’t introduce stronger mitigation measures and vaccination rates. Transmission This paper says that wildfire smoke makes COVID-19 more transmissible. Statistics +553 cases, +1… Continue reading 2021-08-18 BC

Vaccines There has been a lot of discussing recently about waning effectiveness of vaccines. I want to editorialize for a moment: you expect vaccine effectiveness against infection to appear worse in real life than in the studies, and to appear worse over time. More time to get infected. If the vaccine is 95% effective over… Continue reading 2021-08-18 General

Variants This article talks about a lot of things, but says: Breakthrough cases appear to be increasing for Delta. However, they don’t give any “before” numbers, and it’s not clear if it’s just because the number of vaccinated people is increasing. The absolute number of breakthrough cases is still low. The average age of a… Continue reading 2021-08-17 General

Vaccines In this preprint, they found antibody levels post-vax were (slightly) higher in women, younger people, Moderna vaccinees (vs. Pfizer), people who had prior COVID-19, and those who had significant side-effects. If I understand this table correctly, you are more likely to have significant side effects after dose 1 if you were over 60, female,… Continue reading 2021-08-16 General
