I read it in a trustworthy newspaper. A professional discovered it was just a strain of flu (Of course this would be kept from reaching news stations and front page). Not related to the flu pigs can get. Ilness can have much worse effects if a persons state of mind believes that what they have may kill them. So when people caught what they thought was swine flu they most likely just had a flu and becuase the person thought it had to be swine flu they convinced themselves that they needed the injection or they were going to die. My sister thought she had swine flu during the epidemic and i was perfectly healthy?
Obviously it was 'just a strain of flu'. That's part of the definition of being a 'flu'. But yes, pigs could catch that.
And you're referring to a reverse-placebo effect... the evidence for that is not that strong, and even then it rarely occurs that severely.
Of course, Swine Flu wasn't a particularly deadly strain anyway, but it was highly contagious - more so than seasonal flu.
What I was getting to is that some people have been exposed to the H1N1 strand before, because thats what the Avian Flu was, and that was probably one of the worst pandemics we've experienced (at least, I think thats what my Bio teacher told us). Anyway, if a person were to be immune to it, its probably because they or a family member have been exposed to the H1N1 strand by either the Avian flu or some oher means.
Avian flu is H5N1, not H1N1.
