On Oct. 10, 2022, Novavax announced that Switzerland’s Federal Office of Public Health had recommended Nuvaxovid (NVX-CoV2373) as a heterologous and homologous booster for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 in adults aged 18 and older. The FOPH recommended use of Nuvaxovid as an adult booster regardless of previous vaccine history as part of its autumn 2022 COVID-19 vaccine booster campaign.

The recommendation followed presentation of data describing the durability and breadth of immune response following heterologous and homologous boosting. This included data demonstrating Nuvaxovid can induce a functional immune response against currently circulating Omicron subvariants and that the immune response to these subvariants became more potent with subsequent boosting.
