Protein Sciences announced the approval of an extended shelf life for Flublok Quadrivalent vaccine from 6 to 9 months.

Flublok Quadrivalent, a recombinant high-antigen vaccine, confers protection against four strains of the influenza virus and has three times the active ingredients than other quadrivalent flu vaccines. In a large clinical study, greater efficacy was seen with Flublok Quadrivalent vs. a standard quadrivalent flu vaccine in adults ≥50 years. Patients who were administered Flublok Quadrivalent had a 43% reduced risk of getting culture-confirmed influenza vs. patients who received the standard vaccine.

Flublok Quadrivalent was approved by the FDA in October 2016 for use in adults aged >18 years; Trivalent Flublok was launched in 2013. Flublok is developed in a 100% egg-free system and is highly purified. It does not contain any preservatives, egg proteins, gelatin or latex.
