Response to Aristus (Reply #10)

15. My research came from the CDC website.

The article in the OP cites CDC information for this year. Hardly Google, Jenny McCarthy, or great aunt Regret.

You apparently do not understand that the strains suggested annually by the WHO consultation and adopted by FDA for the US are, on average, very poor matches for the strains that show up in any given year. Over the past 4 cycles, the match is about 50% - a little better for influenza B, a little worse for influenza A. But basically a coin toss.

This year it is worse than usual for the most dangerous strains - the match is only about 10%. That means that there is little protection offered by the vaccine this year becuase 90 out of 100 strains an individual will encounter are not targeted by this year's vaccine.

So this year my unvaccinated self is nearly as safe from influenza as your vaccinated self.
