Washington Post: Omicron variant more resistant to vaccine but causes less severe covid, major South African study concludes. “Omicron appears to cause less severe illness than earlier variants of the coronavirus but is more resistant to the two-dose Pfizer-BioNTech vaccine widely used in South Africa, according to the first major private study since omicron was first detected last month. The study by Discovery Health, South Africa’s largest health insurer, of 211,000 positive coronavirus cases, of which 78,000 were attributed to omicron, showed that risk of hospital admissions among adults who contracted covid-19 was 29 percent lower than in the initial pandemic wave that emerged in March 2020.”
