    TLDR People in high-income countries are more likely to accept COVID-19 booster doses than those in middle or low-income countries.
    This study assessed the acceptance of COVID-19 vaccine booster doses in 14 East Mediterranean Region countries using the health belief model, with 2,327 participants. Acceptance rates were highest in high-income countries (83.0%) compared to middle (67.9%) and low-income countries (73.4%). Key determinants for acceptance included age, information from Ministry of Health websites, perceived susceptibility and severity of COVID-19, and perceived risk of side effects. The main reasons for rejecting boosters were beliefs about their lack of benefit and severe side effects. The study suggested that interventions based on the health belief model could help increase booster dose acceptance.
