To control the rise in Neisseria meningitidis strain W infections, during 2018-2019, the Netherlands launched a catch-up meningococcal conjugate (MenACWY) vaccination campaign for teenagers (13-18 years of age). Applying a mental models approach, we surveyed teenagers and their parents about their knowledge and beliefs about meningococcal disease, the MenACWY vaccination, vaccinations in general, and their MenACWY vaccination intentions. Using random forest analysis, we studied predictions of vaccination intentions by knowledge and beliefs. Survey response rate was 52.8% among teenagers and 59.4% among parents. MenACWY vaccination intentions were best predicted by knowledge and beliefs about vaccinations in general, surpassing knowledge and beliefs about meningococcal disease and the MenACWY vaccination. For teenagers, their parents' intention that the teenager be vaccinated was a strong predictor of the teenagers' own vaccination intention. To optimize vaccination uptake during future outbreaks, we recommend that communications emphasize the effectiveness and safety of vaccines and continue to focus on parents.
为了控制脑膜炎奈瑟菌 W 菌株感染的上升，在 2018-2019 年期间，荷兰为青少年（13-18 岁）发起了一场脑膜炎球菌结合疫苗（MenACWY）补种运动。我们采用心智模型方法，调查了青少年及其父母对脑膜炎球菌病、MenACWY 疫苗接种、一般疫苗接种以及他们的 MenACWY 疫苗接种意愿的了解和看法。我们使用随机森林分析研究了知识和信仰对疫苗接种意愿的预测。青少年的调查回应率为 52.8%，家长的回应率为 59.4%。一般疫苗接种的知识和信仰最能预测 MenACWY 疫苗接种的意愿，超过了对脑膜炎球菌病和 MenACWY 疫苗接种的了解和看法。对于青少年来说，其父母希望青少年接种疫苗的意愿是青少年自身接种疫苗意愿的有力预测因素。为了在未来的疫情爆发期间优化疫苗接种率，我们建议在沟通中强调疫苗的有效性和安全性，并继续关注家长。
