WASHINGTON, United States — A preliminary US study of nearly 70,000 Covid positive people showed a substantially reduced risk of hospitalization and death from Omicron even after controlling for growing population immunity levels.
The analysis was conducted on data from the Kaiser Permanente Southern California hospital system, which serves a population of around 4.7 million people, between November 30, 2021, and January 1, 2022, when both strains were circulating widely. “This study controlled for important key parameters such as age, sex, prior SARS-CoV-2 infection, prior vaccination and comorbidities,” CDC director Rochelle Walensky told reporters on a briefing call Wednesday.
