There are six vaccine companies in the US to provide the vaccine every year. The h1N1 is the same as last years. The CDC recommends all over the age of 6 months get a vaccine. There’s also a new strain of flu being spread from pigs at livestock events so perhaps one area to watch. This strain is called the H3N2v and it is reported that it may spread easier than other strains of the flu. This strain does not have a vaccine yet, but they are working on it. One of the best defenses as usual is to wash hands. BD
(CBS/AP) The new flu vaccine for the upcoming 2012-2013 influenza season has been approved by The Food and Drug Administration.
Each year the FDA works with the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) to design a vaccine to protect against the three viral strains most likely to cause the flu in the upcoming year. This year's vaccine has one strain in common with last year's vaccine, plus two new viral strains its targeting.
These strains are:
- A/California/7/2009 (H1N1)-like virus (same strain as 2011-2012 flu season)
- A/Victoria/361/2011 (H3N2)-like virus
- B/Wisconsin/1/2010-like virus.
The vaccine will be manufactured by six companies, including GlaxoSmithKline, Sanofi and Novartis.
