Vaccines against COVID-19 available in Brazil

Abstract

SARS-CoV-2 is a virus that triggered a worldwide disaster after causing deaths in many countries and infecting millions of people causing the disease COVID-19. Several vaccines were developed in record time to contain the pandemic. This study aimed to identify, analyze and compare, through a literature review, the scientific publications on the different vaccines against COVID-19 administered in Brazil. For this, a qualitative literature review was carried out using recently published articles, obtained from the Pubmed, Scielo, Capes, and Lilacs platforms, as well as from the websites of the World Health Organization, Oswaldo Cruz Foundation, and other trustworthy health organizations, seeking relevant information, such as the different types of technologies used for the development of vaccines,  composition, efficacy rates, expiration date, storage, doses, administration, adverse effects and contraindications of each manufacturer of vaccines against COVID-19. This study concluded that the four immunizers administered in Brazil: CoronaVac, AstraZeneca, Pfizer, and Janssen, showed reliability, efficacy, and few side effects. With the advance of vaccination, there was a decrease in severe cases and deaths caused by SARS-CoV-2.
