As of 2015 "Week 1" ending Jan 10th (http://www.cdc.gov/flu/weekly/), almost all the flu tested is type A, almost all of that that is further tested is H3N2, and of those further tested, 35% responds well to the Northern hemisphere vaccine, 65% does not.
What's annoying is that of the 65% that's further tested, it's a good match for the vaccine we're preparing for the 2015 Southern Hemisphere vaccine. So the public health types were on the ball, just not quite fast enough, especially given the very long lead time required for the current major egg based vaccine (both to develop new seed strains that'll grow well in eggs, and then production).
Ah, well, it's a good time for introverts like myself to practice "social distancing", made a lot less onerous by the net. My father mentioned a couple of days ago that the local Catholic high school, wiped out by a tornado in 2011 and finally reopened in its new permanent building for this semester, elected to close and disinfect after not very many days, so many students had or were coming down with the flu.
Yikes, is it normally that low? I looked up a quick figure for 2013, and it was 60% effectiveness.
