To fight the COVID-19 pandemic, messenger RNA (mRNA) vaccines were the first to be adopted by vaccination programs worldwide. We sought to investigate the short-term effect of mRNA vaccine administration on endothelial function and arterial stiffness. Thirty-two participants (mean age 37 ± 8 years, 20 men) who received the BNT162b2 mRNA COVID-19 vaccine were studied in three sessions in a sequence-randomized, sham-controlled, assessor-blinded, crossover design. The primary outcome was endothelial function (assessed by brachial artery flow-mediated dilatation (FMD)), and the secondary outcomes were aortic stiffness (evaluated with carotid-femoral pulse wave velocity (PWV)) and inflammation (measured by high-sensitivity C-reactive protein (hsCRP) in blood samples). The outcomes were assessed prior to and at 8 h and 24 h after the 1st dose of vaccine and at 8 h, 24 h, and 48 h after the 2nd dose. There was an increase in hsCRP that was apparent at 24 h after both the 1st dose (−0.60 [95% confidence intervals [CI]: −1.60 to −0.20], p = 0.013) and the 2nd dose (maximum median difference at 48 h −6.60 [95% CI: −9.80 to −3.40], p < 0.001) compared to placebo. The vaccine did not change PWV. FMD remained unchanged during the 1st dose but decreased significantly by 1.5% (95% CI: 0.1% to 2.9%, p = 0.037) at 24 h after the 2nd dose. FMD values returned to baseline at 48 h. Our study shows that the mRNA vaccine causes a prominent increase in inflammatory markers, especially after the 2nd dose, and a transient deterioration of endothelial function at 24 h that returns to baseline at 48 h. These results confirm the short-term cardiovascular safety of the vaccine. © 2022, The Author(s), under exclusive licence to The Japanese Society of Hypertension.
