Abstract

Importance

Individuals with schizophrenia are at higher risk for severe COVID-19 illness and severe breakthrough infection following vaccination. It is unclear whether immune response to vaccination differs in this population.

Objective

To assess whether anti-SARS-CoV-2 spike antibody titers after vaccination differ in people with a diagnosis of schizophrenia or schizoaffective disorder (SZ) compared to controls without a psychiatric disorder.

Design

This cohort study assessed antibody response following the first and second dose of mRNA vaccines at longitudinal timepoints, up to 7 weeks following the first dose of vaccine.

Setting

A multi-center study including psychiatric healthcare settings in the United States and Europe.

Participants

205 adults with no history of COVID-19 infection, including 106 individuals with SZ and 99 controls without a psychiatric disorder, who received their first dose of SARS-CoV-2 mRNA vaccine between December 20, 2020 and May 27, 2021.

Main outcomes and measures

Mean SARS-CoV-2 anti-Spike IgG antibody levels within 7 weeks after the first dose of vaccination.

Results

A total of 205 individuals (mean [SD] age, 44.7 [12.0] years; 90 [43.9%] male) were included, of which 106 (51.7%) were diagnosed with SZ. SZ was associated with lower mean log antibody levels (−0.15; 95% CI, −0.27 to −0.03, P = 0.016) after adjusting for age, sex, body mass index, smoking, days since vaccination, and vaccine manufacturer. In secondary analyses of dose-specific responses, SZ was associated with a lower mean log antibody level after the second dose of vaccine (−0.23; 95% CI -0.39 to −0.06, P = 0.006), but not the first dose of vaccine (0.00; 95% CI -0.18— 0.19, P = 0.96).

Conclusions and Relevance

In this cohort study of individuals with SZ and a control group without psychiatric disorders, SZ was associated with lower SARS-CoV-2 anti-spike antibody levels following 2 doses of SARS-CoV-2 mRNA vaccination. This highlights the need for further studies assessing vaccine immunogenicity in individuals with schizophrenia.

精神分裂症和分裂情感障碍患者对 SARS-CoV-2 mRNA 疫苗的抗穗状病毒抗体反应
重要性精神分裂症患者在接种疫苗后发生严重 COVID-19 疾病和严重突破性感染的风险较高。目的评估精神分裂症或分裂情感性障碍(SZ)患者接种疫苗后的抗SARS-CoV-2尖峰抗体滴度与无精神障碍的对照组相比是否存在差异。设计这项队列研究评估了接种第一剂和第二剂 mRNA 疫苗后抗体反应的纵向时间点,最长时间为接种第一剂疫苗后 7 周。参与者205名无COVID-19感染史的成年人,包括106名SZ患者和99名无精神障碍的对照者,他们在2020年12月20日至2021年5月27日期间接种了第一剂SARS-CoV-2 mRNA疫苗。结果共纳入 205 人(平均 [SD] 年龄 44.7 [12.0] 岁;男性 90 [43.9%]),其中 106 人(51.7%)被诊断为 SZ。在对年龄、性别、体重指数、吸烟、接种天数和疫苗生产商进行调整后,SZ 与较低的平均对数抗体水平相关(-0.15;95% CI,-0.27 至 -0.03,P = 0.016)。在剂量特异性反应的二次分析中,SZ 与第二剂疫苗后较低的平均对数抗体水平相关(-0.23;95% CI -0.39 至 -0.06,P = 0.006),但与第一剂疫苗无关(0.00;95% CI -0.18- 0.结论和相关性在这项针对 SZ 患者和无精神障碍对照组的队列研究中,SZ 与接种 2 剂 SARS-CoV-2 mRNA 疫苗后较低的 SARS-CoV-2 抗尖峰抗体水平有关。这强调了进一步研究评估精神分裂症患者疫苗免疫原性的必要性。
