On June 30, 2022, the U.S. Food and Drug Administration (FDA) published a recommendation for COVID-19 vaccine manufacturers to update the composition of future booster doses to include additional coverage against the omicron variant. As the SARS-CoV-2 virus evolves, highly transmissible variants such as omicron continue to spread rapidly with symptoms ranging from mild to severe illness. The most severe outcomes, such as hospitalization and death, have been greatly reduced with currently approved and authorized COVID-19 vaccines. Current COVID-19 vaccines provide some protection against the omicron variant, but studies have shown that the effectiveness of these vaccines decreases over time. Therefore, the FDA has advised vaccine developers to update the booster doses of their COVID-19 vaccines to include an omicron component.
