Trust in pharmaceuticals and vaccine hesitancy: exploring factors influencing COVID-19 immunization among Lebanese children aged 1 to 11 years

INTRODUCTION: The COVID-19 pandemic is a serious threat to everyone’s health. Numerous studies have demonstrated that vaccines are very effective in preventing COVID-19-related severe illness, hospitalization, and death. Children’s vaccination exerts its protecting effect by preventing the spread of the virus. The purpose of this study was to analyze the rate of COVID-19 immunization among Lebanese children aged 1 to 11 years and assess parental factors that affect immunization rates. METHODS: An online cross-sectional study was conducted between January and March 2023. The online survey was distributed across all social media channels, including the Ministry of Public Health website. RESULTS: A total of 390 parents filled the survey (mean age = 37.48 ± 8.39 years; 50.5% mothers; 70% with a university level of education). Mothers compared to fathers, having a history of bad reaction to a vaccine vs. not, and higher vaccine hesitancy were significantly associated with less willingness to administer the vaccine to the child. Trusting pharmaceutical companies was significantly associated with more willingness to administer the vaccine to the child. CONCLUSION: The results of this study show that the factors associated with parents’ decisions to vaccinate their children may vary. Our findings conclude that vaccine acceptance is being highly associated with parental concerns, trust, and information regarding the vaccine safety and efficacy.
