Abstract：
The rapid development of COVID-19 vaccines became essential for addressing the global pandemic. Reactive arthritis after vaccination has been a rare phenomenon. Here, we present a case series of three patients with joint inflammation possibly attributed to COVID-19 immunization (mRNA and live adenovirus vectored vaccine). Symptoms were alleviated using non-steroid anti-inflammatory drugs and glucocorticoids. After follow-up, the patients have not been diagnosed with any other rheumatic disease. Reactive arthritis after the COVID-19 vaccine is an unusual adverse effect and poses a negligible risk in comparison to the benefits of immunization, but it should be considered in differential diagnostics by a practicing rheumatologist who cares for patients with new-onset arthritis without apparent cause at the time of pandemic.
摘要：
COVID-19疫苗的快速发展对于应对全球大流行至关重要。疫苗接种后的反应性关节炎是一种罕见的现象。这里,我们提供了3例可能归因于COVID-19免疫(mRNA和活腺病毒载体疫苗)的关节炎症患者的病例系列.使用非甾体抗炎药和糖皮质激素可缓解症状。随访后,这些患者没有被诊断出患有任何其他风湿性疾病。COVID-19疫苗接种后的反应性关节炎是一种不寻常的不良反应，与免疫接种的益处相比，风险可以忽略不计，但是在鉴别诊断中，应该由执业的风湿病学家考虑，他在大流行时照顾没有明显原因的新发关节炎患者。
