1. what cell-based quadrivalent influenza vaccine (surface antigen, inactivated) seqirus suspension for injection in pre-filled syringe is and what it is used for

Cell-based Quadrivalent Influenza Vaccine (Surface Antigen, Inactivated) Seqirus suspension for injection in pre-filled syringe is a vaccine against flu (influenza). Cell-based Quadrivalent Influenza Vaccine (Surface Antigen, Inactivated) Seqirus suspension for injection in pre-filled syringe is prepared in cell cultures, and, therefore, is egg-free.

When a person is given the vaccine, the immune system (the body’s natural defence system) will produce its own protection against the influenza virus. None of the ingredients in the vaccine can cause flu. Cell-based Quadrivalent Influenza Vaccine (Surface Antigen, Inactivated) Seqirus suspension for injection in pre-filled syringe is used to prevent flu in adults and children from 2 years of age.

The vaccine targets four strains of influenza virus following the recommendations by the World Health Organisation for the 2020/2021 season.
