Despite World Health Organization and Nigerian recommendations for hepatitis B birth-dose (HepB-BD) vaccination, only one-third of Nigerian newborns receive timely HepB-BD vaccination, This study identified facilitators to increasing HepB-BD vaccination based on data from a crowdsourcing open call in Nigeria.
Our team conducted an open call across Nigeria for teams to submit ideas on how to increase HepB-BD vaccination. Independent judges evaluated the submissions based on predefined criteria. We analyzed textual data from the top 29 entries using iterative coding and thematic analysis within a socioecological model to identify priority facilitators.
The open call received 362 total submissions, and 58.5% (215/362) of submissions were from women. Analysis of the top 29 submissions revealed 6 priority facilitators for increasing HepB-BD vaccination: (1) engage religious and healthcare leaders to educate pregnant women; (2) strengthen national policies for vaccination support and tracking; (3) counter misconceptions to promote attitude and behavior changes; (4) utilize rural infrastructure like town halls and radio programs to disseminate information; (5) translate educational materials into local languages like pidgin; and (6) organize financial or social incentives.
Our crowdsourcing open call identified key facilitators and strategies for increasing HepB-BD vaccination among Nigerian newborns. The findings from this study can inform HepB-BD initiatives in Nigeria and other low- and middle-income countries.
尽管世界卫生组织和尼日利亚都建议进行乙肝首剂疫苗（HepB-BD）接种，但只有三分之一的尼日利亚新生儿及时接种了HepB-BD疫苗。本研究基于尼日利亚众包公开征集的数据，确定了促进HepB-BD疫苗接种增加的因素。
我们的团队在尼日利亚全国范围内进行了一次公开征集，邀请各团队提交关于如何增加HepB-BD疫苗接种的想法。独立评委根据预先确定的标准对提交的内容进行评估。我们使用社会生态模型中的迭代编码和主题分析，对前29份参赛作品的文本数据进行分析，以确定优先促进因素。
公开征集共收到362份参赛作品，其中58.5%（215/362）的作品来自女性。对前29份参赛作品的分析揭示了增加HepB-BD疫苗接种的6个优先促进因素：（1）让宗教和医疗保健领袖参与，对孕妇进行教育；（2）加强国家疫苗接种支持和跟踪政策；（3）消除误解，促进态度和行为改变；（4）利用市政厅和广播节目等农村基础设施传播信息；（5）将教育材料翻译成洋泾浜等当地语言；（6）组织经济或社会激励措施。
我们的众包公开征集确定了在尼日利亚新生儿中增加HepB-BD疫苗接种的关键促进因素和策略。本研究的结果可为尼日利亚及其他低收入和中等收入国家的HepB-BD疫苗接种计划提供参考。
