As an inactivated vaccine like BBIBP-CorV and the Sinovac COVID-19 vaccine, BBV152 uses a more traditional technology that is similar to the inactivated polio vaccine. Initially, a sample of SARS-CoV-2 was isolated by India's National Institute of Virology and used to grow large quantities of the virus using vero cells. From then on, the viruses are soaked in beta-propiolactone, which deactivates them by binding to their genes, while leaving other viral particles intact. The resulting inactivated viruses are then mixed with an aluminium-based adjuvant.
