Principais efeitos adversos das vacinas contra a Covid-19 na população de Valença-RJ

Abstract

Introduction:SARS-COV-2 is a single-stranded RNA virus and its transmission occurs primarily through airborne respiratory droplets. The easy contagion and the possibility of transmission, even by asymptomatic carriers, provided the opportunity for the exacerbated spread of the virus. Faced with the high rate of deaths and the lack of suitable drug treatment, an intense investment and development of effective vaccines against Covid-19 begins around the world. Methodology: A collection of adverse effects reported at the immunization center by the vaccinated population of Valença-RJ was carried out, comparing CoronaVac and as and AstraZeneca, equating the prevalence of adverse effects, their severity and possible correlation with age group.Results: A total of 114 notifications were collected, 105 of the AstraZeneca vaccine and 09 of the CoronaVac. A prevalence of AstraZeneca vaccine effects is seen in the younger population, whereas CoronaVac notifications are more prevalent in older populations.Discussion: AstraZeneca had a higher number of adverse effects compared to CoronaVac, and in both vaccines these reported effects are mainly the very common and common ones observed in the package insert.Conclusion: It is noticed that there is an underreporting of adverse effects to vaccines, because, within a target population of 64,589, almost fully vaccinated, only 114 people had reports of unwanted symptoms. In addition, of the few adverse events collected, most of these were mild, demonstrating the safety of vaccines against COVID-19.
