Abstract

Abstract:

Objective To understand the influenza vaccination situation of children under 16 years old in Shanghai and parents' awareness of influenza and influenza vaccines, analyze the influencing factors of influenza vaccination, and provide a reference basis for improving the influenza vaccination rate and preventing the prevalence of influenza among children. Methods A total of 527 subjects from Yangpu District and Baoshan District in Shanghai were selected from September 2024 to February 2025, by convenience sampling for a questionnaire survey. The questionnaire included an influenza vaccination status survey and a self-made survey on knowledge about influenza and the influenza vaccine. Multivariate logistic regression was used to analyze factors associated with childhood influenza vaccination. Results A total of 527 questionnaires were distributed, 525 were collected, and 506 were valid, yielding an effective rate of 96.4%. Among the 506 children, 244 (48.2%) were boys and 262 (51.8%) were girls, with a median age of 8 (5-11) years. A total of 287 children (56.7%) had been vaccinated against influenza, of whom 133 had received at least one dose, 76 were vaccinated only during the flu season, and 78 were vaccinated annually; 219 children (43.3%) had never been vaccinated. The main reason why parents are willing to have their children vaccinated against the flu is to prevent flu infection, while concerns about vaccine safety were the main reasons parents were unwilling to vaccinate their children or reluctant to vaccinate again. Multivariate logistic regression showed that history of preterm birth (OR=0.38, 95% CI: 0.18-0.83), parents working in government agencies, enterprises, or institutions (OR=2.03, 95% CI: 1.06-3.86), parents engaged in social production and living services (OR=3.22, 95% CI: 1.40-7.40), and the influenza knowledge (OR=1.24, 95% CI: 1.08-1.44) were all correlated with childhood influenza vaccination status (P<0.05). Conclusions The childhood influenza vaccination rate still needs improvement, especially for special groups such as preterm infants; vaccine safety remains a major concern for parents.

Key words: influenza vaccine, inoculation, influencing factor, child
