A Reliable Supply of Flu Vaccine
GSK quadrivalent influenza vaccines are produced at different manufacturing sites to help provide confidence in supply reliability.
Ensuring you have the vaccine supply you need
The process of producing our GSK quadrivalent influenza vaccines begins as soon as we receive the seasonal viruses. Achieving our goal—delivering a safe, reliable supply of vaccine—requires many sequential steps.
We manufacture our vaccines at two sites. This helps ensure we have an adequate, uninterrupted supply of vaccine, ready for timely delivery.
Two brands manufactured at separate secure locations
