Influenza (Flu) Vaccines
Affinity Vaccines supplies and administers Quadrivalent and Trivalent Influenza Vaccines from globally trusted manufacturers including GSK, Sanofi Pasteur, and Abbott.
All influenza vaccines are updated yearly according to World Health Organization (WHO) recommendations to match the circulating influenza strains for the upcoming flu season.
These vaccines are suitable for corporate immunization programs, occupational health requirements, and dependent vaccination campaigns.
A. Quadrivalent Influenza Vaccines (Four-Strain Formulation)
Quadrivalent vaccines protect against four influenza virus strains:
- Two Influenza A strains (H1N1 and H3N2)
- Two Influenza B strains (one from each lineage: Victoria and Yamagata)
This broader coverage ensures better protection against the flu and its variants.
