This document provides a summary of references and documents related to mRNA vaccines. It aims to report interesting references that can help better understand what independent researchers have found, mainly focused on the public debate around the presence or absence of graphene derivatives in some COVID-19 vaccine vials. Relevant classic articles, white papers, and other documents are useful for clarifying crucial aspects of the infectious disease, its epidemiology, and the efficacy of preventive, therapeutic, or vaccine measures. While some of the referenced studies and documents have limitations, reviewing them can generate hypotheses or open public discussion on important topics, given mRNA vaccines were introduced via emergency authorization with reduced testing time and lack of official quality information on raw materials.
