It was determined that review of the sBLA for FluMist® Quadrivalent by the Vaccines and Related Biological Products Advisory Committee (VRBPAC) was not required because of CBER’s experience with the currently licensed FluMist® and because FluMist® Quadrivalent manufacturing is similar to the procedures used for the currently licensed FluMist® formulation. Furthermore, because our review of information submitted in the supplement, including the clinical study design and trial results, did not raise concerns or controversial issues which would have benefited from an advisory committee discussion, it was agreed that discussion of the review of this sBLA by the VRBPAC was not necessary.
