UNIVERSITY EXTENSION: VACCINATION STATUS AND SEROLOGICAL PROFILE FOR IMMUNOGLOBULINS AGAINST SARS-COV-2 OF PARTICIPANTS AT THE HEALTH PREVENTION FAIR IN VALE VERDE, RS

Abstract

University extension enables an integral approach to the health-disease and teaching-learning process, with emphasis on community health promotion, prevention and education. Covid-19 is a highly transmissible and morbimortality respiratory infection caused by the SARS-CoV-2 virus. The production of a safe and effective vaccine became promising in combat the pandemic. The objective of this study was to evaluate the vaccination status and serological profile for immunoglobulins against SARS-CoV-2 of the participants of a health fair in Vale Verde (RS). This is a cross-sectional, descriptive-quantitative study, with data obtained through interviews and rapid tests for IgG and IgM. 52 people were tested, of which 17,30% had already tested positive and most had already received the 1st or 2nd dose of the vaccine (44,23% and 32,69%, respectively). Of those tested, 23,07% showed reactive IgG and 3,84% reactive IgM. As for the type of vaccine, 25 people were vaccinated with AstraZeneca/Fiocruz (20,00% obtained reagent IgG of which 5 reported previous disease), 10 with Sinovac/Butantan, 2 with Pfizer/Wyeth and 3 with Janssen. Unvaccinated individuals with no previous disease report tested non-reactive IgG and IgM. Thus, it’s concluded that 11,53% of the population tested was already fully immunized and had IgG antibodies. This study reinforces that rapid test is an easy-to-perform and low-cost method used for epidemiological screening or diagnostic aid of Covid-19, however it isn’t specific for evaluating the vaccine response, with vaccination being a potential solution for the control of the disease pandemic associated with the prevention measures already established.
