Considering all the misinformation and silly science put out about this flu going around can you really blame them. I know people who I'd consider reasonably intelligent who believe this is the plague. Letting stories get about that if you don't get vaccinated you won't be allowed into supermarkets is simply asking for conspiracy theories. The government PR has been atrocious on this. I'm not an anti-vaccer but I won't be getting the vaccine because I don't need it.
