Flu Vaccine (cont.)

Viral Strains and Producers of the Seasonal Flu Vaccines for 2014-2015

For the 2013-2014 flu season, for the first time, the seasonal flu vaccine was composed of four different flu antigens instead of the usual three; the 2014-2015 viral strains are the same used in the 2013-2014 vaccines. The trivalent vaccine is also still available. The CDC indicates the following: The 2014-2015 U.S. trivalent influenza vaccines will contain an A/California/7/2009 (H1N1)-like virus, an H3N2 virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011, and a B/Massachusetts/2/2012-like virus. Quadrivalent (containing four viral types) vaccines will include an additional vaccine virus, a B/Brisbane/60/2008-like virus. The CDC has speculated that the quadrivalent vaccine will replace the trivalent vaccine in the future. In addition, a quadrivalent nasal spray vaccine is now available.

The following is a list of the FDA-approved seasonal (2014-2015 flu season) vaccines and the companies that name and manufacture them as of August 2014:

  • Sanofi Pasteur
  • Novartis
  • MedImmune, LLC
  • ID Biomedical Corporation of Quebec
  • CSL Limited
  • GlaxoSmithKline
  • Protein Sciences
  • bioCSL

Caregivers are strongly advised to read the package inserts to check for indications and contraindications before administering any type of vaccine, especially new vaccines, as sometimes the indications for use and contraindications change. Readers are advised to view an extensive table (
) that the CDC developed for each vaccine type and producer to describe the individual features of each vaccine. In addition, there are updates made occasionally about who should get what type of vaccine.
