Americans have become increasingly alarmed about the swine flu, but many are wary about getting vaccinated against the disease, according to a new Washington Post-ABC News poll. A majority of those surveyed—5%—now say they are "a great deal" or "somewhat" worried that they or someone in their household will be infected with it, up from 39% of those polled in August. At the same time, however, more than six in 10 say they will not get vaccinated, and only 52% of parents say they plan to have their children vaccinated.
