His staff have all either received or opted not to receive the hepatitis B vaccine. All of his medical staff have undergone PPD testing. Several of his nurses are concerned about their possible exposure to smallpox in the upcoming year. His staff is mostly under 30 years of age and therefore never received smallpox vaccinations
