Omicron Inactivated COVID-19 Vaccine (Vero Cell)

The **Omicron Inactivated COVID-19 Vaccine (Vero Cell)** is an inactivated vaccine developed to protect against COVID-19 caused by the Omicron variant of SARS-CoV-2. It uses whole virions of the Omicron strain propagated in Vero cells—a continuous cell line derived from African green monkey kidney cells—then inactivated (typically with beta-propiolactone or formaldehyde) to preserve key antigens while eliminating infectivity. The mechanism involves intramuscular injection to induce neutralizing antibodies and T-cell responses targeting the SARS-CoV-2 spike protein and other viral components, mimicking natural infection without causing disease. Primarily indicated for active immunization against symptomatic COVID-19 in adults and children, it was authorized in several countries including China, Indonesia, and others for booster use against Omicron subvariants.
