Humoral response to SARS-CoV-2 has been studied, predominantly the classical IgG and its
subclasses. Although IgE antibodies are typically specifc to allergens or parasites, a few reports describe their production in response to SARS-CoV-2 and other viruses. Here, we investigated IgE specifc to receptor...
ABSTRACT: Vaccines are critical cost‐effective tools to control the COVID‐19 pandemic. The heterologous prime‐boost vaccination has been used by many countries to overcome supply issues, so the effectiveness and safety of this strategy need to be better clarified. This study aims to verify the effe...
Vaccination certainly is the best way to fight against the COVID‐19 pandemic. In this study, the seroconversion effectiveness of two vaccines against severe acute respiratory syndrome coronavirus 2 was assessed in healthcare workers: virus‐inactivated CoronaVac (CV, n= 303), and adenovirus‐vectored...
Enumera os testes de diagnóstico COVID-19 aprovados pela ANVISA - Agência Nacional de Vigilância Sanitária, de acordo com as Resoluções nº 766 de 18 de março de 2020, nº 777 de 18 de março de 2020, nº 839, de 20 de março de 2020, nº 840, de 20 de março de 2020, nº 841, de 20 de março de 2...
Background: In Brazil, mathematical models for derivingestimates and projections of COVID-19 cases have been developed without data on asymptomatic SARS-CoV-2 infection. We estimated the seroprevalence of antibodies to SARS-CoV-2 among blood donors in the State of Rio de Janeiro.
Methods: Data w...
