The role of severity perceptions and beliefs in natural infections in Shanghai parents’ vaccine decision-making: a qualitative study

摘要

BackgroundChina has reduced incidence of vaccine-preventable diseases through its Expanded Program on Immunization (EPI). Vaccines outside of the EPI are not provided for free by the government, however. This study explored how the stated importance of different disease and vaccine-related attributes interacted with beliefs about the immune system of a child to affect Chinese parents’ decision to obtain a non-EPI vaccine.
