Um, I had several friends get the flu this year. Nasty. Not one of them got vaccinated.
I did. No flu. Family did. No flu. Bunch of other friends did. No flu.
This is anecdotal, but from what I personally saw, the flu vaccine worked just fine this year...
And, even if it didn’t, that says nothing about the efficacy of vaccines generally. Each year’s flu shot is an educated guess - the CDC (and others around the world) track the prevalence of different strains, and predict which strain(s) will be most common. In order to produce enough of the vaccine in time for flu season, this prediction is made months in advance (for the 2014-2015 flu season, the vaccine composition was decided in February 2014). They have a good track record of getting it right, but it is not at all surprising that they might choose the wrong strain(s) in any given year.
I have not had a flu shot since the year of the great H1N1 scare , which was incidentally the last time I actually contracted the flu. No shots, no flu since. This year every person I met who had the flu said they got their shots. I for one will never take another, instead I will continue to get plenty of rest, take vitamins and wash hands often and avoid the flu.
