Abstract

This observational prospective study was conducted on 17 4-shots COVID-19 vaccinated patients who came for a primary consultation. The aim of the study was focused on coagulation biomarkers. The platelet count and D-dimer level were the numeric parameters studied. The study showed a minor decrease of the platelet count in 2 patients (12 %). Conversely, we observed an abnormal elevation of D-dimer levels in 12 patients (71%). In conclusion, this preliminary study on 4-shots COVID-19 vaccinated patients suggests a possible link between a rise in D-dimer and COVID-19 vaccines. Hopefully, it was not correlated with any thrombotic events or prolonged bleeding, but it deserves careful investigation to be sure that this biological alteration is not durable and deleterious.
