Vaccination is key to developing herd immunity against COVID-19; however, the attitude of Nigerians towards being vaccinated stalled at the 70% vaccination target. This study engages Theory of Planned Behaviour to analyse the tone of Nigerian YouTube headlines/titles, and the tone of YouTube users' comments to examine the causes of COVID-19 vaccine hesitancy. YouTube videos uploaded between March 2021 and December 2022 were analysed using a content analytic approach. Results show 53.5% of the videos had a positive tone, while 40.5% were negative, and 6% neutral. Second, findings indicate most of the Nigerian YouTube users' comments were neutral (62.6%), while 32.4%, were negative, and 5% were positive. From the antivaccine themes, analysis shows the people's lack of trust in the government on vaccines (15.7%) and the presence of vaccine conspiracy theories mostly related to expressions of religion and biotechnology (46.08%) were the main causes of COVID-19 vaccine hesitancy in Nigeria. The study presents implications for theory and recommends ways for governments to develop better vaccination communication strategies.
接种疫苗是建立针对新冠病毒的群体免疫的关键；然而，尼日利亚人对接种疫苗的态度在70%的接种目标上停滞不前。本研究运用计划行为理论来分析尼日利亚YouTube上标题的语气，以及YouTube用户评论的语气，以探究新冠疫苗犹豫的原因。采用内容分析方法对2021年3月至2022年12月期间上传的YouTube视频进行分析。结果显示，53.5%的视频语气积极，40.5%为消极，6%为中性。其次，研究结果表明，尼日利亚YouTube用户的评论大多为中性（62.6%），32.4%为消极，5%为积极。从反疫苗主题来看，分析表明民众对政府在疫苗方面缺乏信任（15.7%）以及存在主要与宗教和生物技术表达相关的疫苗阴谋论（46.08%）是尼日利亚新冠疫苗犹豫的主要原因。该研究提出了理论启示，并为政府制定更好的疫苗接种沟通策略推荐了方法。
