AFLURIA, Influenza Virus Vaccine
Suspension for Intramuscular Injection

DRUG DESCRIPTION

AFLURIA, Influenza Virus Vaccine for intramuscular injection, is a sterile, clear, colorless to slightly opalescent suspension with some sediment that resuspends upon shaking to form a homogeneous suspension. AFLURIA (influenza virus vaccine) is prepared from influenza virus propagated in the allantoic fluid of embryonated chicken eggs. Following harvest, the virus is purified in a sucrose density gradient using a continuous flow zonal centrifuge. The purified virus is inactivated with beta-propiolactone, and the virus particles are disrupted using sodium taurodeoxycholate to produce a “split virion”. The disrupted virus is further purified and suspended in a phosphate buffered isotonic solution.

AFLURIA (influenza virus vaccine) is standardized according to USPHS requirements for the 2010-2011 influenza season and is formulated to contain 45 mcg hemagglutinin (HA) per 0.5 mL dose in the recommended ratio of 15 mcg HA for each of the three influenza strains recommended for the 2010-2011 Northern Hemisphere influenza season: A/California/7/2009, NYMC X-181 (H1N1), A/Victoria/210/2009, NYMC X-187 (H3N2) (an A/Perth/16/2009-like strain), and B/Brisbane/60/2008. A 0.25 mL dose contains 7.5 mcg HA of each of the same three influenza strains.

Thimerosal, a mercury derivative, is not used in the manufacturing process for the single dose presentations; therefore these products contain no preservative. The multi-dose presentation contains thimerosal, added as a preservative; each 0.5 mL dose contains 24.5 mcg of mercury.

A single 0.5 mL dose of AFLURIA contains sodium chloride (4.1 mg), monobasic sodium phosphate (80 mcg), dibasic sodium phosphate (300 mcg), monobasic potassium phosphate (20 mcg), potassium chloride (20 mcg), and calcium chloride (1.5 mcg). From the manufacturing process, each 0.5 mL dose may also contain residual amounts of sodium taurodeoxycholate ( ≤ 10 ppm), ovalbumin ( ≤ 1 mcg), neomycin sulfate ( ≤ 0.2 picograms [pg]), polymyxin B ( ≤ 0.03 pg), and beta-propiolactone ( < 25 nanograms). A single 0.25 mL dose of AFLURIA contains half of these quantities.

The rubber tip cap and plunger used for the preservative-free, single-dose syringes and the rubber stoppers used for the multi-dose vial contain no latex.
