The embrace of coronavirus disease 2019 (COVID-19) vaccine conspiracies has been linked to vaccine hesitancy. This study aimed to investigate the relationship between COVID-19 vaccine conspiracy theories and perceived vaccine effectiveness. The study utilized a longitudinal follow-up study in which adults in Chile completed surveys in December 2020 (T1) and May 2021 (T2). The psychometric properties of the five-item instrument on conspiracy theories for the COVID-19 vaccine were evaluated using data from T1 ( = 578). A confirmatory one-factor structure with suitable indicators of reliability was found. The longitudinal analysis ( = 292) revealed that conspiracy theories about the COVID-19 vaccine in T1 were associated with lower beliefs in its effectiveness in T2. However, no significant association was found between beliefs in effectiveness in T1 and conspiracy theories in T2. The study suggests that beliefs in conspiracy theories may temporally precede beliefs in vaccine effectiveness for COVID-19. The results have implications for strategies to address vaccine conspiracy beliefs and their implementation at the public policy level.
对2019冠状病毒病（COVID-19）疫苗阴谋论的信奉与疫苗犹豫有关。本研究旨在调查COVID-19疫苗阴谋论与感知到的疫苗有效性之间的关系。该研究采用了一项纵向随访研究，智利的成年人于2020年12月（T1）和2021年5月（T2）完成了调查。使用T1（n = 578）的数据评估了关于COVID-19疫苗阴谋论的五项量表的心理测量特性。发现了一个具有合适可靠性指标的验证性单因素结构。纵向分析（n = 292）显示，T1时关于COVID-19疫苗的阴谋论与T2时对其有效性的较低信念相关。然而，在T1时对有效性的信念与T2时的阴谋论之间未发现显著关联。该研究表明，对阴谋论的信念可能在时间上先于对COVID-19疫苗有效性的信念。这些结果对解决疫苗阴谋信念的策略及其在公共政策层面的实施具有启示意义。
