[Study on the immunization status and its influencing factors among workers from the polio network laboratories in...

Objective: To Investigate the immune status and influencing factors of provincial polio network laboratory (PNL) workers in China so as to provide evidence for the development of related strategies to protect personnel working at the PNLs. Methods: All the practitioners from the PNLs at the provincial centers for disease control, were selected as objects for this study, from October to December, 2016, under a questionnaire survey. Information on status of immunity and influencing factors was collected, with SAS software, trend chi-square used for statistics analysis. Results: A total of 77 workers were involved in this survey, with 60 (78%) of them completed the polio-based immune program but the rest 17 (22%) remained records unclear. 66 people (about 86%) remembered clearly that they had received vaccination when engaging in the polio-lab work, but the rest 11 (14%) with only partial vaccination records. We also noticed that the Influencing factors realted to vaccination status were: age (χ(2)=2.48, P<0.05), title (χ(2)=2.51, P<0.05), years of employment (P<0.000 1), education (χ(2)=0.74, P=0.46) and gender (χ(2)=0.46, P=0.50). Conclusion: Immune status of the Chinese provincial PNL practitioners appeared fairly good as 86% of all the workers had received polio-related vaccination, with 41% of them completed a 3-time inoculation program, when started working in this field.
