A full two thirds of British nurses are undecided about or outright against getting vaccinated for swine flu, the Telegraph reports. Some 60% of those who plan to decline say they are concerned about the safety of the untested treatment. “I would not be willing to put myself at risk of, as yet, unknown long-term side effects,” one says. Another 31% of nos say there is no need for the vaccine. “I have yet to be convinced there is a genuine health risk,” another says.
