The FDA committee, known as VRBPAC, in charge of evaluating vaccines and related biological products recently voted unanimously that the upcoming 2023-2024 COVID-19 vaccines should be updated with a monovalent XBB strain.
Omicron subvariant BA.2.75 accounted for 75.9% of new COVID-19 cases logged in Thailand from November 26-December 2, from 58.9% in the previous week, according to new data released by the Department of Medical Sciences (DMS).
Covid-19 cases have been on the rise over the past month in Singapore mainly due to the Omicron XBB subvariant with the XBB infection wave expected to peak around mid-November 2022.
People who have never caught Covid-19 or who were infected with the virus before the Delta wave in Singapore in 2021 face a higher chance of catching the new XBB strain of the Omicron variant.
