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.
Exactly. Good description of how the process works (and unfortunately does not on occasion).
But to call it vaccinations “pseudo-science” is ridiculous, as you implied up-thread.
Sorry, to be clear: You correctly (IMHO) implied the comment that “vaccination is pseudo-science” was ridiculous. You clearly did not imply that vaccination was pseudo-science.
IOW, I was agreeing with your statement. (My earlier comment could have been read either way.)
