Gov. Norm Bangerter helps 3-year-old Nicole Brown get ready for her date with a needle Wednesday. Nicole was among several children who got a shot in the arm during Bangerter's visit to the Salt Lake City-County Health Department. Bangerter proclaimed April "Utah Immunization Action Month" and urged all parents to vaccinate their children against potentially deadly diseases. Dr. Suzanne Dandoy, state Health Department director, said Utah has had an unusually high number of cases of whooping cough and other childhood diseases in recent years. A statewide survey of 2-year-olds in 1987 showed that fewer than 60 percent were adequately immunized. Many people are worried about potential side effects to whooping cough vaccinations. "But the risk of a child contracting whooping cough, which can cause death, is worse than the risk from the vaccine," said Dandoy. As part of a monthlong public awareness effort, health officials will conduct immunization clinics at 37 locations statewide on April 15.
