FDA Approves Protein Sciences BLA for Flublok Quadrivalent
FDA has approved a Protein Sciences BLA for its quadrivalent formulation of Flublok influenza vaccine, which protects against four strains of influenza, three of the same strains found in trivalent Flublok plus an additional B strain. Approval was based on data from a clinical study of 9,000 adults 50 years of age and older, which showed that those who received Flublok Quadrivalent were over 40% less likely to get cell-culture confirmed influenza than those that received a leading egg-produced quadrivalent flu vaccine, according to the company. The vaccine is approved for adults 18 and older and will be available in pre-filled syringes beginning in 2017.
