What flu viruses are included in the Northern Hemishere seasonal vaccine for 2011-2012?

WHO recommended that the Northern Hemisphere's 2011–2012 seasonal influenza vaccine contain the following three vaccine viruses:

•an A/California/7/2009 (H1N1)-like virus;
•an A/Perth/16/2009 (H3N2)-like virus; and
•a B/Brisbane/60/2008-like virus.
These are the same viruses that were selected for the Northern Hemisphere for the 2010-2011 influenza vaccine.

dear desrt . . . from this year or last?  

If the influenza vaccine composition is the same for the upcoming season as it was last season, do I need to get vaccinated again?

Yes. People should get vaccinated every year because even if the viruses in the vaccine are the same as the year before, immunity to influenza viruses declines over time and may be too low to provide protection after a year. More information is available about the frequency and timing of flu vaccination.

This year, of course. I get the shot as soon as it becomes available every year (except when I was full of IFN) and it's been available in W Texas for several weeks now.

I was told, when I got my flu shot last Sat., that this year's containing the same formula as the one from last year.  I've been getting flu shots for years.

I am suspicious of everything I put into my body right now because of the experimental meds I am relying on to clear my virus.  I get the flu shot every year too.  Nobody has any objections but I think I will wait until I am three months in.  I am six weeks in today.

We are all advised to get the flu shot every year as liver damage is a chronic disease.  I got it twice on tx (because I treated for 72) and while everyone was dropping around me between the vaccine and lovely interferon I did not.  One good thing about IFN after all....

OK - I give up. WHO?
