On August 30, 2021, the WHO classified the SARS-CoV-2 Mu variant (B.1.621 lineage) as a new variant of interest. The WHO defines “comparative assessment of virus characteristics and public health risks” as primary action in response to the emergence of new SARS-CoV-2 variants. Here, we demonstrate that the Mu variant is highly resistant to sera from COVID-19 convalescents and BNT162b2-vaccinated individuals. Direct comparison of different SARS-CoV-2 spike proteins revealed that Mu spike is more resistant to serum-mediated neutralization than all other currently recognized variants of interest (VOI) and concern (VOC). This includes the Beta variant (B.1.351) that has been suggested to represent the most resistant variant to convalescent and vaccinated sera to date (e.g., Collier et al, Nature, 2021; Wang et al, Nature, 2021). Since breakthrough infection by newly emerging variants is a major concern during the current COVID-19 pandemic (Bergwerk et al., NEJM, 2021), we believe that our findings are of significant public health interest. Our results will help to better assess the risk posed by the Mu variant for vaccinated, previously infected and naïve populations. ### Competing Interest Statement The authors have declared no competing interest.

Christopher Ingraham, of the Why Axis newsletter: The net result of this relentless pressure: even in the midst of a variant surge that’s proven especially lethal in conservative areas, nearly 40 percent of Republicans say they’re either unwilling to get the vaccine or uncertain about it, compared to just 15 percent of Democrats. But the […]

MIAMI (AP) — Funeral director Wayne Bright has seen grief piled upon grief during the latest COVID-19 surge. A woman died of the virus, and as her family was planning the funeral, her mother was also struck down.

I updated the covdata package for the first time in a while, as I’ll be using it to teach in the near future. As a side-effect, I ended up taking a look at what the ongoing polarization or divergence of the COVID experience is like in different parts of the United States. Here I use county-level data to draw out some of the trends. The idea is to take the time series of COVID-19 deaths and split it into deciles by some county-level quantity of interest.

Israelis who had an infection were more protected against the Delta coronavirus variant than those who had an already highly effective COVID-19 vaccine

Background Reports of waning vaccine-induced immunity against COVID-19 have begun to surface. With that, the comparable long-term protection conferred by previous infection with SARS-CoV-2 remains unclear. Methods We conducted a retrospective observational study comparing three groups: (1)SARS-CoV-2-naïve individuals who received a two-dose regimen of the BioNTech/Pfizer mRNA BNT162b2 vaccine, (2)previously infected individuals who have not been vaccinated, and (3)previously infected and single dose vaccinated individuals. Three multivariate logistic regression models were applied. In all models we evaluated four outcomes: SARS-CoV-2 infection, symptomatic disease, COVID-19-related hospitalization and death. The follow-up period of June 1 to August 14, 2021, when the Delta variant was dominant in Israel. Results SARS-CoV-2-naïve vaccinees had a 13.06-fold (95% CI, 8.08 to 21.11) increased risk for breakthrough infection with the Delta variant compared to those previously infected, when the first event (infection or vaccination) occurred during January and February of 2021. The increased risk was significant ( P

Massachusetts schools are likely to face a statewide mask mandate starting Wednesday.

A doctor featured in a Times article published Sunday on the latest wave of COVID-19 speaks for herself in a searing letter to unvaccinated people.

A surge involving the rapidly-transmitting Delta variant in heavily vaccinated countries has led to much hand-wringing that the vaccines are not effective against Delta, or vaccine efficacy wanes after 4-6 months. This has fueled anti-vaccine sentiment suggesting the vaccines are not working, and causing much stress in vaccinated people that they are not as protected as they thought they would be. In this post, I will focus on vaccine efficacy vs. severe disease/hospitalization, which is the ke

Booster doses of Pfizer and Moderna's COVID-19 vaccine will be offered late next month, beginning with those vaccinated first, like health care providers.

Shielding children from danger is a fundamental instinct. Tolerating risk for them is hard—but necessary—emotional work.
