"Dec. 3, 2012 -- The U.S. flu season is here -- the earliest start since the "moderately severe" season of 2003.
Just as in 2003, the nasty H3N2 flu bug is causing most cases so far.
"This could be a bad flu year," warned CDC"...
(Influenza Virus Vaccine)
FLUVIRIN® is a trivalent, sub-unit (purified surface antigen) influenza virus vaccine prepared from virus propagated in the allantoic cavity of embryonated hens' eggs inoculated with a specific type of influenza virus suspension containing neomycin and polymyxin. Each of the influenza virus strains is harvested and clarified separately by centrifugation and filtration prior to inactivation with betapropiolactone. The inactivated virus is concentrated and purified by zonal centrifugation. The surface antigens, hemagglutinin and neuraminidase, are obtained from the influenza virus particle by further centrifugation in the presence of nonylphenol ethoxylate, a process which removes most of the internal proteins. The nonylphenol ethoxylate is removed from the surface antigen preparation.
FLUVIRIN® is a homogenized, sterile, slightly opalescent suspension in a phosphate buffered saline. FLUVIRIN® has been standardized according to USPHS requirements for the 2014-2015 influenza season and is formulated to contain 45 mcg hemagglutinin (HA) per 0.5-mL dose in the recommended ratio of 15 mcg HA of each of the following 3 viruses:
A/Christchurch/16/2010, NIB-74 (H1N1) (an A/California/7/2009-like virus);
A/Texas/50/2012, NYMC X-223 (H3N2); and
B/Massachusetts/2/2012, NYMC BX-51B.
The 0.5-mL prefilled syringe presentation is formulated without preservative. However, thimerosal, a mercury derivative used during manufacturing, is removed by subsequent purification steps to a trace amount ( ≤ 1 mcg mercury per 0.5-mL dose).
The 5-mL multidose vial formulation contains thimerosal, a mercury derivative, added as a preservative. Each 0.5-mL dose from the multidose vial contains 25 mcg mercury.
Each dose from the multidose vial or from the prefilled syringe may also contain residual amounts of egg proteins ( ≤ 1 mcg ovalbumin), polymyxin ( ≤ 3.75 mcg), neomycin ( ≤ 2.5 mcg), betapropiolactone (not more than 0.5 mcg) and nonylphenol ethoxylate (not more than 0.015% w/v).
The tip caps of the FLUVIRIN® prefilled syringes may contain natural rubber latex. The multidose vial stopper and the syringe stopper/plunger do not contain latex.
What are the possible side effects of influenza virus injectable vaccine?
