RESUMO
PURPOSE: Vaccine-preventable diseases have decreased globally. However, measles and diphtheria outbreaks still occur in Southern Thailand, where Muslims are predominant with a documented low vaccine coverage. The purpose of this study was to investigate Muslim parents' beliefs and factors influencing them to complete immunization of children aged 0-5 years in Y.L. province, Thailand. METHOD: A descriptive qualitative study was conducted, using focus group discussion with 26 participants. They are parents whose children had complete or incomplete vaccination and community/religious leaders. Data were analyzed using content-analysis and triangulation method was used to ensure trustworthiness. RESULTS: Four major themes emerged from the analysis: (1) positive vaccine beliefs, which included knowledge and awareness of vaccination, trust in vaccine efficacy, and religious beliefs; (2) positive factors influencing positive beliefs and vaccine acceptance, which were accessibility of reliable sources, and imitation of leaders and health-community-network; (3) negative vaccine beliefs, including bias in vaccine efficacy and safety, personal beliefs about sources of vaccines, and religious misconceptions regarding the value of vaccines and Halal concerns; and (4) negative factors influencing negative beliefs and refusal of vaccination, which were perception of disadvantages of vaccines spread by word-of-mouth, trust in person over empirical evidence, religious views based on self-interpretation, and lack of public information on Halal vaccines. CONCLUSION: Both positive and negative factors influencing complete immunization were found in this study. To enhance vaccine acceptance, health care providers should understand Muslim cultural beliefs by offering parents a chance to express their attitudes and encourage vaccination via religious leaders and community role models.
