Abstract

The durability of the immunogenicity elicited by three doses of mRNA-based BNT162b2 and whole-virus inactivated CoronaVac in patients with neuromuscular diseases, particularly those on immunosuppressive drugs and variants of concern, has not been well-established. Our goal was to evaluate medium-term humoral immunogenicity outcomes after 3 doses of these vaccines. Peripheral blood samples were collected from participants 14-49 days and 155-210 days after administration of the third vaccine dose to assess humoral immune responses through serological assays. The immunogenicity outcomes of each patient were compared to those of three age-matched healthy control participants, ensuring a balanced comparison. Both patients that received 3 doses of BNT162b2 and 10 (90.9%) patients that received CoronaVac seroconverted against wild-type-SARS-CoV-2 virus, showing comparable antibody responses to healthy participants. After 6 months, one patient in BNT162b2 and all four patients in CoronaVac groups maintained seropositivity. The JN-1 specific binding antibody response was lower compared to wild-type virus. The use of corticosteroids did not affect seroconversion rate against wild-type virus or JN.1 variant. BNT162b2 and CoronaVac were immunogenic for neuromuscular diseases patients, maintaining durability after 6 months even for those on corticosteroids. Our data support a rapid immunization series utilizing mRNA-based and whole-virus inactivated vaccines for future pandemic.

香港神经肌肉病患者三次服用 BNT162b2 和 CoronaVac 的中期免疫原性。
对于神经肌肉疾病患者,尤其是使用免疫抑制剂和相关变体的患者,三剂基于 mRNA 的 BNT162b2 和全病毒灭活的 CoronaVac 所引起的免疫原性的持久性尚未得到很好的证实。我们的目标是评估接种 3 次这些疫苗后的中期体液免疫原性结果。我们在注射第三剂疫苗 14-49 天和 155-210 天后收集了参与者的外周血样本,通过血清学检测评估体液免疫反应。将每位患者的免疫原性结果与三位年龄匹配的健康对照者的免疫原性结果进行比较,以确保比较结果的均衡性。接受3剂BNT162b2的患者和接受CoronaVac的10名患者(90.9%)都对野生型SARS-CoV-2病毒产生了血清转换,显示出与健康参与者相当的抗体反应。6 个月后,BNT162b2 组的一名患者和 CoronaVac 组的所有四名患者仍保持血清阳性。与野生型病毒相比,JN-1 特异性结合抗体反应较低。使用皮质类固醇不会影响对野生型病毒或JN.1变体的血清转换率。BNT162b2 和 CoronaVac 对神经肌肉疾病患者具有免疫原性,即使使用皮质类固醇的患者也能在 6 个月后保持持久性。我们的数据支持利用基于 mRNA 的全病毒灭活疫苗为未来的大流行提供快速免疫系列。

期刊介绍: (formerly Human Vaccines; issn 1554-8619) Vaccine research and development is extending its reach beyond the prevention of bacterial or viral diseases. There are experimental vaccines for immunotherapeutic purposes and for applications outside of infectious diseases, in diverse fields such as cancer, autoimmunity, allergy, Alzheimer’s and addiction. Many of these vaccines and immunotherapeutics should become available in the next two decades, with consequent benefit for human health. Continued advancement in this field will benefit from a forum that can (A) help to promote interest by keeping investigators updated, and (B) enable an exchange of ideas regarding the latest progress in the many topics pertaining to vaccines and immunotherapeutics. Human Vaccines & Immunotherapeutics provides such a forum. It is published monthly in a format that is accessible to a wide international audience in the academic, industrial and public sectors.
