Vaccines This article reports COVID-19 patients who got a flu shot had significantly fewer complications than patients who did not. COVAX is getting 100M doses immediately from Sinopharm and Sinovac. This is great news. It’s not enough, of course, but double what COVAX has distributed already. (There’s another 390M coming later, which is also great… Continue reading 2021-07-12 General

Immunity This study estimates that immunity to COVID-19 from being infected will last 1,717 days. Variants The Delta variant does not fuck around. From Our World In Data: Border This article says that more people are trying to enter Canada from the US, but they are turning away about half of them, mostly because they… Continue reading 2021-07-11 General

Vaccines This article says that the Sputnik V vaccine is turning out to be a good one, with effectiveness in the 90% range — and not just with Russian data, either. (I still wouldn’t get one because of the quality control problems which Brazil uncovered.)

VOCs This report from Public Health England says that Delta now makes up 97% of the genotyped cases. This report from Public Health England says that there have been a few cases of Lambda from international travel, but it does not seem to be out-competing Delta and does not seem to be particularly vax-evasive. It… Continue reading 2021-07-09 General

Vaccines Pfizer says that a third shot boosts antibody levels 5x to 10x against COVID Classic and Beta. Remember that antibodies aren’t the whole story, and that Pfizer has incentive to get as many people as possible to buy their vax. They also said they are working on a Delta-specific booster. The US FDA immediately… Continue reading 2021-07-08 General

Vaccines A few days ago, there was a Israeli Ministry of Health report saying that Pfizer was only 64% effective against the Delta strain, which was far lower than other studies had found. It looks like the study in Israel was against all infection, including asymptomatic infection, while the others were against symptomatic infection. That… Continue reading 2021-07-07 General

Vaccines In yesterday’s General blog post, I pointed to a study from Israel that said that Pfizer was only 64% effective. This thread does a takedown of that study. This preprint also says that AZ+Pfizer is a lot better (in test tubes, anyway) than AZ+AZ, and even a bit better than Pfizer+Pfizer. Disease This article… Continue reading 2021-07-06 General

Seroprevalence This study from 18 June 2021 found that at the end of the second wave, between 5 and 6% of Canadians had antibodies to COVID-19, up from 2% after the first wave. Vaccines This study (done in Ontario) says that Moderna scores best against all the variants, and that Moderna does well against Delta… Continue reading 2021-07-03/04/05 General

Mitigation Measures Trudeau put in writing that the border stays closed to foreign nationals entering from anywhere but the United States until 75% of the population (not the adults, not the eligible) are fully vaxxed. The “anywhere but the United States” is interesting, I think it basically bans air travel. Foreign nationals entering from the… Continue reading 2021-07-02 General

Testing You might have heard of “Lateral Flow Tests”. They are a type of rapid test which has been deployed widely in the UK. This study evaluated six different brands of lateral flow tests and found that they are less sensitive than PCR tests, but most of them are still pretty good. Long COVID This… Continue reading 2021-07-01 General
