Table 6 Examples of comments from pediatricians representing fears and concerns regarding PCV materials in rotavirus vaccines.

"I assume you'll have people asking if it's related to swine flu if you write the name out like that. Doesn't 'porcine' mean, 'related to pigs'? Everybody's obsessed with swine flu right now, so that always worries people."

"...there are a lot of things that start within the animal population that transfer over to humans and can be far more devastating."

"Then I started thinking about the 'what-ifs' that [my patients' parents] will be asking; 'Well about that avian thing, the avian flu? It never caused a problem in anybody else, but then it found a way to combine with a human type virus."

"A lot of my [patients'] parents don't eat pork. They're very naturalist [sic]. They're going to see pork, and then they'll see virus. And they're going to stop there, and they're going to say I don't want my child to get this vaccine. They'll assume there's another virus in it, and they'll think of swine flu, pork, and then it just becomes this whole association that they'll go crazy with."
