Flu vaccine makers CSL Seqirus, Sanofi and GSK kick off initial shipments ahead of upcoming season

The dog days of summer might be in full swing, but for flu vaccine makers, its a busy time prepping for this fall's influenza season.

CSL Seqirus said it kicked off influenza vaccine shipments on July 9, when it began to ship out its three options, according to a press release. The company’s portfolio includes unique offerings such as Flucelvax, the “first and only” cell-based influenza vaccine and Fluad, which is recommended by the Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practices (ACIP) for people 65 and older.
