FDA Approves Flublok Quadrivalent

October 11, 2016 - The U.S. FDA approved a quadrivalent (effective against four different influenza strains) formulation of its Flublok® (influenza vaccine), manufactured by Protein Sciences Corporation. Flublok Quadrivalent is indicated for adults 18 and older. Flublok Quadrivalent contains more active antigens than other flu vaccines available in the U.S. therefore, it may provide better protection than vaccines with fewer antigens, particularly for individuals who are 50 and older and patients with immunocompromising conditions. Additionally, all Flublok vaccines are recombinant, they are made in cultured cells without antibiotics, animal cells, eggs, live influenza virus or preservatives. Flublok Quadrivalent will be launched next year in pre-filled, single-dose syringes for intramuscular (IM) injection. 


Adverse reactions or quality problems experienced with the use of a recalled product may be reported to the FDA’s MedWatch Adverse Event Reporting Program either online, by regular mail or by fax.

Actual drug patent expiration dates and availability of new medications are subject to change due to patent litigation, settlement agreements, additional patents, exclusivities, and final FDA approval.  Distribution and availability of new medications at pharmacies may not occur immediately following FDA approval.  Patients are advised to speak with their healthcare professional or pharmacist regarding appropriateness as well as actual availability.
