Influenza A H1N1 Monovalent Vaccine

Influenza A (H1N1) 2009
Monovalent Vaccine

DRUG DESCRIPTION

Influenza A (H1N1) 2009 Monovalent Vaccine, an inactivated influenza virus vaccine, for intramuscular use, is prepared from influenza viruses propagated in embryonated chicken eggs. The virus-containing allantoic fluid is harvested and inactivated with formaldehyde. Influenza virus is concentrated and purified in a linear sucrose density gradient solution using a continuous flow centrifuge. The virus is then chemically disrupted using a non-ionic surfactant, polyethylene glycol p-isooctylphenyl ether (Triton® X-100), producing a “split virus”. The split virus is further purified and then suspended in sodium phosphate-buffered isotonic sodium chloride solution.

Influenza A (H1N1) 2009 Monovalent Vaccine is formulated to contain 15 mcg hemagglutinin (HA) of influenza A/California/07/2009 (H1N1) v-like virus per 0.5 mL dose. Gelatin 0.05% is added as a stabilizer. Each 0.5 mL dose may contain residual amounts of formaldehyde (not more than 100 mcg), polyethylene glycol p-isooctylphenyl ether (not more than 0.02%), and sucrose (not more than 2.0%).

There is no thimerosal used in the manufacturing process of the single-dose presentations of Influenza A (H1N1) 2009 Monovalent Vaccine. The multi-dose presentation of Influenza A (H1N1) 2009 Monovalent Vaccine contains thimerosal, a mercury derivative, added as a preservative. Each 0.5 mL dose of the multidose presentation contains 25 mcg mercury.

Influenza A (H1N1) 2009 Monvalent Vaccine is a sterile clear to a slightly opalescent suspension.

Antibiotics are not used in the manufacture of Influenza A (H1N1) 2009 Monovalent Vaccine.

All presentations of Influenza A (H1N1) 2009 Monovalent Vaccine do not contain latex.
