Mechanism of action

The vaccine contains inactivated influenza virus antigens that are administered intramuscularly to trigger both humoral (antibody-mediated) and cellular immune responses. This prepares the immune system to recognize and neutralize circulating influenza viruses, reducing infection risk and disease severity. The University of Hong Kong's formulation is in phase 3 development, likely investigating improved immunogenicity or broader strain coverage compared to existing vaccines.
