Key result
Parents who perceived vaccines as being important for their children were significantly more likely to report that their children had been vaccinated against polio (aOR 1.31), highlighting targets for improving suboptimal population immunity.
Why the study?
Polio eradication has been set back substantially by the COVID-19 pandemic, with detections in high-income countries suggesting suboptimal population immunity despite routine childhood immunization.

What factors are associated with polio vaccine hesitancy in the Western Pacific Region?
Odds Ratio: 1.31 (95% CI 1.04–1.66)
p-value: p=0.023
Mei et al. (2022) conducted a cross-sectional in Polio vaccine hesitancy (n=18,442). Perception that vaccines are important for children vs. Perception that vaccines are not important was evaluated on Self-reported child polio vaccination status (aOR 1.31, 95% CI 1.04-1.66, p=0.023). Parents who perceived vaccines as being important for their children were significantly more likely to report that their children had been vaccinated against polio (aOR 1.31), highlighting targets for improving suboptimal population immunity.
