The FDA has endorsed the World Health Organizations picks for the 2015-2016 flu vaccines. It seems weird that they would pick these strains already as the virus still has a lot of time to regenerate and change.
But nonetheless it is important that they pick the strains early enough so that they have time to develop the vaccines. They have decided to choose 2 new strains to join the one from last year for this next season. There will be an H3N2, H1N1, and type B virus available for the next season. A member of the Vaccines and Related Biological Products Advisory Committee said that the committee watches the viruses that affect Asia and the Southern Hemispheres as most of the viruses seem to drift westward as well as northward, and then they base the selections off of that.
