HPV vaccine uptake remains low in China, especially among girls. Recently, China has initiated a pilot program on HPV immunization for girls 9–14. From November to December 2021, a cross-sectional study was conducted among parents of girls 9–14 in China through a web-based anonymous online questionnaire survey. Descriptive epidemiological analysis was used to analyze parental acceptability. Hierarchical regression analysis and structural equation modeling were to determine associated factors. A total of 5623 participants were included in the analysis. 21.2% girls had received HPV vaccine, and 94.3% parents intended to receive vaccination for their daughters, the Kappa values between them was −0.016. 31.9% of vaccinated mothers had received HPV vaccine for their daughters, vaccination history had a positive impact on behavior (β = 0.048). Attitude (β = 0.186), subjective norms (β = 0.148) and perceived behavioral control (β = 0.648) had a positive impact on intention. Vaccination intention mediated the relationships between attitude (β = 0.044), subjective norms (β = 0.035), and perceived behavioral control (β = 0.154) with behavior. There is a gap between vaccination intention and behavior in parents of girls 9–14. Perceived behavior control had a strong association on HPV vaccination behavior.

This study evaluated different varicella vaccination strategies in Jiangsu province, China. A decision-tree Markov model was used to evaluate the cost effectiveness of various varicella vaccination strategies for children, including direct and selective vaccination (serotesting pre-vaccination). A cohort of one-year-old children was followed through 60 one-year Markov cycles. The parameter estimation was based on field work, the literature, and statistical yearbooks. We calculated the incremental cost-utility ratio (ICUR) using the saved quality-adjusted life year (QALY). One-way and probability sensitivity analyses were performed to assess uncertainty. Among 100,000 cohort members, one-dose and two-dose direct vaccination averted 8061 and 10,701 varicella cases, respectively, compared with no vaccination. Furthermore, compared with no vaccination, one-dose and two-dose direct vaccination saved one QALY at the ICUR of USD 21,401.33 and USD 35,420.81, respectively, at less than three times the per capita gross domestic product (USD 47,626.86) of Jiangsu. The ICURs of the one-dose and two-dose selective strategies versus no vaccination were USD 42,623.62 and USD 51,406.35 per QALY gained, respectively. The cost effectiveness results were most sensitive to the QALY loss of outpatients and vaccine prices. Thus, in Jiangsu, one-dose and two-dose direct varicella vaccination in children could be cost effective at the willingness to pay threshold of three times provincial GDP per capita from a societal perspective. The findings were sensitive to the vaccine price and health utility of varicella cases.

This study aimed to estimate the disease burden and health-related quality of life (HRQOL) among patients with severe hand, foot, and mouth disease (HFMD) in Jiangsu Province, China. We analyzed the surveillance data of HFMD cases in Jiangsu Province from 2009 to 2020. Moreover, a cross-sectional study was conducted in Nanjing and Suzhou, China, between January 2017 and May 2018. Patients with severe HFMD and their parents were recruited from selected hospitals. Questionnaires and hospital management systems were used to collect data on direct economic burden. The HRQOL of children was assessed using the TNO-AZL Preschool Quality of Life (TAPQOL) scale. A total of 1,348,737 confirmed cases of HFMD were reported to the NNDRS in Jiangsu province during 2009–2020. Of these, 9,622 were severe cases, with 62 (.64%) of these being fatal. From January 2017 to May 2018, data was collected from 362 severe HFMD cases using a structured questionnaire. The median per capita direct economic burden was RMB 16142.88, and was associated with the region and length of hospital stay (P

Evidence for the validity and reliability of the World Health Organization’s 10-item vaccine hesitancy scale (VHS) in different settings is not sufficient, especially for criteria validity. This study aimed to assess the validity and reliability of the VHS using child vaccination data in China. A cross-sectional survey was performed with parents of 19–48-month-old children at six vaccination clinics in Wuxi City between September and October 2020. The VHS was revised to category A (expanded program on immunization, EPI) VHS and category B (Non-EPI) VHS. Factor analysis was used to confirm the latent domain and to assess the model structure. The average variance extracted (AVE) was calculated to assess convergent validity, and Cronbach’s α and composite reliability (CR) were used to determine internal consistency. The association between VHS scores and children’s vaccination status was examined to assess criteria validity using logistic regression. The survey response rate was 75.3% (n = 802). Two factors were identified, explaining 64.60% and 63.34% of the common variance in categories A and B VHS, respectively. The Cronbach’s α of > 0.7 and CR of >0.7 in the scale indicated the VHS has acceptable internal consistency. The AVE values indicated that convergent validity was not ideal for the VHS. There were no statistically significant associations between VHS scores and vaccination status, indicating that the criterion validity was not ideal. The VHS needs improvement before becoming a standard survey tool.

Background Vaccine hesitancy was listed as one of the top 10 issues threatening global health in 2019. The objectives of this study were to (a) use an extended protection motivation theory (PMT) with an added trust component to identify predictors of vaccine hesitancy and (b) explore the predictive ability of vaccine hesitancy on vaccination behavior. Methods We conducted an online questionnaire from February 9 to April 9, 2021, in China. The target population was Chinese residents aged 18 and over. A total of 14,236 responses were received. Structural equation modeling was used to test the extended PMT model hypotheses. Results A total of 10,379 participants were finally included in this study, of whom 52.0% showed hesitancy toward vaccination. 2854 (27.5%) participants reported that they got flu shots in the past year, and 2561 (24.7%) participants were vaccinated against COVID-19. 2857 (27.5%) participants engaged in healthcare occupation. The model explained 85.7% variance of vaccine hesitancy. Self-efficacy was the strongest predictor, negatively associated with vaccine hesitancy (β = −0.584; p
