TL;DR Summary

The World Health Organization (WHO) advisory group has recommended that this year's COVID-19 booster shots be updated to target one of the currently dominant XBB variants, specifically XBB.1.5 or XBB.1.16. The group suggested no longer including the original COVID-19 strain in future vaccines, based on data that the original virus no longer circulates in human beings and shots targeting the strain produce "undetectable or very low levels of neutralizing antibodies" against currently circulating variants. COVID-19 vaccine makers are already developing versions of their respective vaccines targeting XBB.1.5 and other currently circulating strains.
