Abstract

Background: To date, little is known about the evidence of a potential risk of psychiatric adverse events following COVID-19 vaccination in large populations with adequate study design.

Aims: To investigate whether COVID-19 vaccination is associated with increased risk of psychiatric adverse events.

Method: We used South Korea's linkage database to obtain registry data and claims data from 2019 to 2021, and conducted a population-based self-controlled case series study including 11 751 806 individuals. Primary outcomes included anxiety/nervousness, mood disorders, perceptual disturbances/psychoses, aggression/behavioural disturbances, cognitive impairments and sleep disorders within 21 days of COVID-19 vaccination. Secondary outcomes were the stratified primary outcomes according to each individual's psychiatric history. Conditional Poisson regression was used to estimate incidence rate ratios (IRR) and 95% confidence intervals.

Results: COVID-19 vaccination did not increase the rate of anxiety and nervousness (adjusted IRR 0.95, 95% CI 0.95-0.96), mood disorders (adjusted IRR 0.75, 95% CI 0.75-0.76), perceptual disturbances and psychoses (adjusted IRR 0.72, 95% CI 0.70-0.74), aggression and behavioural disturbances (adjusted IRR 0.93, 95% CI 0.89-0.97), cognitive impairment (adjusted IRR 0.68, 95% CI 0.67-0.69) or sleep disorders (adjusted IRR 0.90, 95% CI 0.89-0.91). Secondary outcomes were consistent with the primary outcome, although the adjusted IRRs for anxiety and nervousness (adjusted IRR 1.17, 95% CI 1.15-1.18) and sleep disorders (adjusted IRR 1.07, 95% CI 1.06-1.09) were statistically significant in individuals with no history of psychiatric disorders. Sensitivity analyses showed consistent results with our main findings.

Conclusions: Our findings provide short-term safety profiles for COVID-19 vaccines regarding psychiatric adverse events. Continuous monitoring of anxiety/nervousness or sleep disorders after COVID-19 vaccination is required regardless of history of psychiatric comorbidities.

COVID-19疫苗接种后精神不良事件的短期风险：全国自我对照病例系列研究

背景：迄今为止，在有充分研究设计的大量人群中，关于COVID-19疫苗接种后精神不良事件潜在风险的证据知之甚少。目的：探讨COVID-19疫苗接种是否与精神不良事件风险增加相关。方法：利用韩国联动数据库获取2019 - 2021年的登记数据和理赔数据，开展基于人群的自我对照病例系列研究，共纳入11 751 806人。主要结局包括在COVID-19疫苗接种后21天内的焦虑/紧张、情绪障碍、知觉障碍/精神病、攻击/行为障碍、认知障碍和睡眠障碍。次要结局是根据每个人的精神病史分层的主要结局。使用条件泊松回归估计发病率比（IRR）和95%置信区间。结果：COVID-19疫苗接种并未增加焦虑和紧张（调整IRR 0.95, 95% CI 0.95-0.96）、情绪障碍（调整IRR 0.75, 95% CI 0.75-0.76）、知觉障碍和精神病（调整IRR 0.72, 95% CI 0.70-0.74）、攻击和行为障碍（调整IRR 0.93, 95% CI 0.89-0.97）、认知障碍（调整IRR 0.68, 95% CI 0.67-0.69）或睡眠障碍（调整IRR 0.90, 95% CI 0.89-0.91）的发生率。次要结局与主要结局一致，尽管焦虑和紧张（调整后的IRR为1.17,95% CI为1.15-1.18）和睡眠障碍（调整后的IRR为1.07,95% CI为1.06-1.09）在没有精神疾病史的个体中具有统计学意义。敏感性分析结果与我们的主要发现一致。结论：我们的研究结果提供了COVID-19疫苗在精神不良事件方面的短期安全性概况。无论是否有精神合并症史，都需要在COVID-19疫苗接种后持续监测焦虑/神经或睡眠障碍。
