Trust in vaccines and medicines in Uganda

Trust underlies numerous decisions in health care, affecting vaccine uptake as well as care seeking rates, treatment adherence, and health outcomes. Although trust in the doctor-patient relationship has garnered much attention, trust in health care commodities such as vaccines and medicines has rarely been examined. We report findings from a cross-sectional survey to assess trust in vaccines vis-à-vis their trust in conventional medicines and traditional medicines in Uganda. Trust in vaccines, conventional and traditional medicines were assessed by adapting the vaccine hesitancy scale developed by the SAGE Working Group on Vaccine Hesitancy. Reported trust in vaccines and conventional medicines was much higher than trust in traditional medicines. Significant associations were observed between trust in vaccines and trust in conventional medicines. Of the trust components explored, respondents were most concerned about access to and safety of vaccines and medicines. Further, respondents' previous health care experiences, primary source of health information, and trust in providers' skills were significantly associated with reported trust in vaccines and medicines. Although strong levels of trust in vaccines and conventional medicines were observed overall, the findings identify areas where policies and communication efforts can focus to strengthen trust.
