I think the study is flawed because the numbers are wrong and the numbers are wrong because no-one was taking an accurate count by any stretch of the imagination. I know this because I lived it, I saw it and i remember it. How on earth can you stop counting, not even have a reliable method of counting, and then claim to have accurate data? It doesn't really matter what the thing being counted may be, whether its H1N1 victims, jellybeans in a jar or bunny rabbits in a yard, you can't have flawed data and accurate results... you just can't.
That's why things like "statistical relevance" exist. Statistics is all about trending, because it is
impossible to have a 100% sample on anything, heck, look how many people shirk the census!
I can say that the vaccination/response worked 100% in our household, and that included getting DW (who was pregnant at the time and high risk) her vaccine within 2 days of them being released to our State Health Department. As a Type I diabetic, I was also promptly given the vaccine, and DD (who was 2 at the time) received her 2 doses from her pediatrician. They actually called us as soon as it came in.
To me the response by the news, the WHO, and the CDC, while much too "doom and gloom" for me, was swift, and I think it had far more reaching effects than just getting people vaccinated. I've seen people at my place of work who wouldn't even use a napkin for lunch, now making sure to wash their hands frequently, and taking care not to spread germs and such.
As to the "new strains" being found across the globe, more research is necessary. They are finding out that the deaths from the 2009 pandemic may have been linked to a mutation of the virus that only occurred in a very minute % of those infected. If that's the case, the current group of deaths (which aren't nearly what they were in 2009), could be linked to that same, singular, mutation, and
not to a general mutation.
Regardless, the CDC has released reports that the "possible" mutations they've studied in Arizona are covered by the current vaccination. In addition anyone who suffered through H1N1 are now showing a very broad scope of antibodies in their system. These antibodies, supposedly, produce a resistance to many of the most virulent flu strains in history. So, the fact that the OP had the virus may, in the long run, be a good thing.
