GlaxoSmithKline announced it has begun shipping the 2015–2016 formulation of Fluarix Quadrivalent (influenza virus vaccine) and expects to begin shipping Flulaval Quadrivalent (influenza virus vaccine) in August to healthcare providers.

The company also made the decision to switch to 100% quadrivalent formulations following customer demand from the 2014–2015 flu season and early pre-booking for this season. Quadrivalent vaccines are designed to help protect against two different types of “A” flu strains and two types of “B” flu strains.
