Understanding the factors influencing parental decision-making is critical to improving vaccine uptake among children. This study aimed to determine parents&rsquo; intentions regarding COVID-19 vaccination for children aged 3&ndash;18 years in Guilan Province using the BASNEF model.<br> <strong>Methods</strong>: This analytical cross-sectional study included 688 parents selected using multistage cluster random sampling. Data were collected using a structured questionnaire comprising demographic information, knowledge, and BASNEF model constructs. Data were analyzed using SPSS software, version 21, and the significance level was set at P<0.005.<br> <strong>Results</strong>: Stepwise multiple regression analysis revealed that subjective norms (P<0.001), attitudes (P<0.001), knowledge (P<0.001), maternal decision-making (P=0.001), joint parental decision-making (P<0.001), parental vaccination status (P=0.03), and having a vaccinated child (P=0.002) collectively explained 56% of the variance in parental behavioral intentions.<br> <strong>Conclusion</strong>: Knowledge, attitudes, subjective norms, and decision-making patterns strongly influence parents&rsquo; intention to vaccinate children against COVID-19. The BASNEF model identifies these factors and guides targeted strategies to improve vaccine uptake.&nbsp;</span></font></p> Intention, COVID-19 vaccine, BASNEF Model, Knowledge 507 518 http://jrh.gmu.ac.ir/browse.php?a_code=A-10-2667-1&slc_lang=en&sid=1 Narjes Nikpey n.nikpey1994@gmail.com 100319475328460048857 100319475328460048857 No Health and Environment Research Center, Guilan University of Medical Sciences, Rasht, Iran.
