Study finds Omicron BA.2 responsible for more but less infectious breakthrough infections

In a recent study posted to the medRxiv* pre-print server, researchers evaluated the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron (B.1.1.529) infections between December 23, 2021, and February 20, 2022, in Qatar to understand how Omicron subvariants, vaccination, and prior infection status impacted these cases.
