随着严重急性呼吸综合征冠状病毒2型的出现,使用了一类新的疫苗BNT162b2和mRNA-1273进行免疫。这两种疫苗都基于一种mRNA分子,该分子编码严重急性呼吸综合征冠状病毒2的病毒刺突(S)糖蛋白。虽然可有效预防COVID-19(2019冠状病毒病)的严重表现,但已报告了不良反应,包括血液系统疾病和心肌炎和心包炎等心血管并发症。在此背景下,迫切需要更好地了解对基于covid -19的mRNA疫苗的生理反应及其对健康的短期和长期影响。血管内皮在COVID-19的发病机制中起核心作用,因此可能参与COVID-19 mRNA疫苗的一些急性心血管副作用。然而,仅有2项研究直接考察了这些疫苗对血管功能的影响,且评估是在接种后的不同时期进行的。1,2在短期内,健康成人在接受第二剂BNT162b2治疗24小时后,肱动脉血流介导的扩张功能短暂受损。迄今为止,mRNA-1273疫苗是否对脉管系统产生相同的作用,以及疫苗接种后血管舒张功能短暂变化的潜在机制尚不清楚。因此,本研究的目的是评估COVID-19 mRNA疫苗(BNT162b2和mRNA-1273)在接种后48小时对健康成人血管内皮功能和一氧化氮(NO)介导的血管舒张的短期影响。
With the emergence of severe acute respiratory syndrome coronavirus 2, a new class of vaccines, BNT162b2 and mRNA-1273, were used for immunization. Both vaccines are based on an mRNA molecule that encodes the viral spike (S) glycoprotein of severe acute respiratory syndrome coronavirus 2. While efficacious at preventing severe manifestations of COVID-19 (coronavirus disease 2019), adverse effects have been reported, including hematologic disorders and cardiovascular complications such as myocarditis and pericarditis. In this context, a better understanding of the physiological responses to COVID-19-based mRNA vaccines and their short-and long-term effects on health are crucially needed.The vascular endothelium plays a central role in the pathogenesis of COVID-19 and may therefore be involved in some of the acute cardiovascular side effects of COVID-19 mRNA vaccines. However, only 2 studies have directly examined the impact of these vaccines on vascular function, and the assessments were conducted during different period following vaccination. 1, 2 In the short term, flow-mediated dilation of the brachial artery was transiently impaired in healthy adults 24 hours after a second dose of BNT162b2. 1 To date, it is still unknown whether mRNA-1273 vaccine elicits the same effect on the vasculature nor the potential mechanisms responsible for the transient changes in vasodilatory function postvaccination. The aim of this study was therefore to evaluate the short-term effects of COVID-19 mRNA vaccines (BNT162b2 and mRNA-1273) on vascular endothelial function and nitric oxide (NO)-mediated vasodilation in healthy adults 48 hours after vaccination.
