(Influenza Vaccine) for Intramuscular Injection
FLULAVAL, Influenza Vaccine, for intramuscular injection, is a trivalent, split-virion, inactivated influenza virus vaccine prepared from virus propagated in the allantoic cavity of embryonated hens' eggs. Each of the influenza viruses is produced and purified separately. The virus is inactivated with ultraviolet light treatment followed by formaldehyde treatment, purified by centrifugation, and disrupted with sodium deoxycholate.
FLULAVAL is a sterile, opalescent, translucent to off-white suspension in a phosphatebuffered saline solution that may sediment slightly. The sediment resuspends upon shaking to form a homogeneous suspension.
FLULAVAL has been standardized according to USPHS requirements for the 2014-2015 influenza season and is formulated to contain 45 micrograms (mcg) hemagglutinin (HA) per 0.5mL dose in the recommended ratio of 15 mcg HA of each of the following 3 strains: A/California/7/2009 NYMC X-179A (H1N1), A/Texas/50/2012 NYMC X-223A (H3N2), and B/Massachusetts/2/2012 NYMC BX-51B.
The prefilled syringe is formulated without preservatives and does not contain thimerosal. Each 0.5-mL dose from the multi-dose vial contains 50 mcg thimerosal ( < 25 mcg mercury); thimerosal, a mercury derivative, is added as a preservative.
Each 0.5-mL dose of either presentation may also contain residual amounts of ovalbumin ( ≤ 0.3 mcg), formaldehyde ( ≤ 25 mcg), sodium deoxycholate ( ≤ 50 mcg), α-tocopheryl hydrogen succinate ( ≤ 240 mcg), and polysorbate 80 ( ≤ 665 mcg) from the manufacturing process. Antibiotics are not used in the manufacture of this vaccine.
The tip caps and plungers of the prefilled syringes are not made with natural rubber latex. The vial stoppers are not made with natural rubber latex.
