Kiến thức chăm sóc trẻ sau tiêm chủng của cha mẹ có con dưới 2 tuổi tại huyện Thường Tín, Hà Nội năm 2025 và một số yếu tố liên quan

Vaccination is a cornerstone of public health, significantly reducing childhood morbidity and mortality worldwide. While vaccines are generally safe and effective, the potential for post-vaccination reactions necessitates vigilant care. Adequate parental knowledge regarding post-vaccination child care is paramount to ensure vaccine safety and optimize health outcomes, yet previous studies suggest this knowledge may be insufficient. This study aims to evaluate the knowledge of post-vaccination child care among parents of children under two years old in Thuong Tin District, Hanoi, and identify associated factors to inform targeted interventions.

Healthcare professionals, public health policymakers, and parents interested in child vaccination safety and health education.

This cross-sectional study investigated the level of knowledge regarding post-vaccination child care among 424 parents of children under two years old in Thuong Tin District, Hanoi, conducted from January to June 2025. Employing probability sampling and face-to-face interviews with a pre-designed questionnaire, the research aimed to assess parental understanding and identify factors influencing it. The findings revealed that only 47.9% of parents possessed adequate overall knowledge of post-vaccination child care. While understanding of immunization benefits (89.4%), required observation at the vaccination site (99.3%), and continuous home monitoring (91.7%) was high, awareness of specific post-vaccination symptoms needing attention varied widely (45.3% to 99.3%). Multivariable logistic regression analysis identified several associated factors influencing this knowledge: parents with three or more children, an education level above high school, being a government officer or public servant, and accessing three or more sources of information (p<0.05). These results highlight the critical need for enhanced health education strategies. The study recommends targeted attention towards parents with lower educational attainment and unstable occupations or incomes to ensure more effective and comprehensive communication, ultimately improving vaccine safety and efficacy in the community. The insights derived have significant implications for public health programs focusing on child health and preventative care.
