Mechanism of action

The vaccine contains chemically inactivated (killed) SARS-CoV-2 virions that cannot replicate. When administered, these viral particles trigger both humoral (antibody) and cell-mediated immune responses, priming the immune system to recognize and neutralize live virus upon exposure. This approach has been used successfully in other viral vaccines such as polio and influenza.
