This survey for Tucson Adults will ask questions related to their knowledge, opinions, and beliefs about COVID-19 and seasonal influenza, and preventative measures people take to protect themselves against these diseases. This study will help the Pima County Health Department understand what might be preventing people from getting vaccinated to protect themselves from getting sick with COVID-19 and seasonal influenza. Using the responses, we will be able to focus our vaccine promotion efforts more effectively and reduce the number of respiratory illnesses within the community of Pima County.
