COMPLICAÇÕES NEUROLÓGICAS DECORRENTES DAS QUATRO VACINAS CONTRA O COVID-19 UTILIZADAS NO BRASIL

Abstract

In December 2019, a new pathology emerged and left the world on alert, a viral respiratory disease, with the power to affect other systems, with high transmissibility, caused by the SARS-CoV-2 virus, being assigned the name of Coronavirus Disease 2019 (COVID-19), spreading and affecting different peoples and nations, evolving into a pandemic context and definition in a short period of time. The development of effective and safe immunizers in record time was the goal of several governments and pharmaceutical companies, joining efforts with teaching institutions and research centers, different vaccines were developed, with different methodologies, some techniques already consolidated and present in vaccines, used in immunization programs, such as vaccines based on inactivated virus, and other vaccines with technologies not previously used, which were in the development phase, such as immunizers based on Messenger RNA (mRNA), but all with proven safety. However, due to the short time of research and field tests carried out quickly, a possible gap was left open for possible complications, or adverse reactions, documented in the short, medium and long term, since administration performed in an extensive population group and different results can be observed, regarding the increase in the incidence of already expected complications or the addition of new adverse reactions.
