RESUMO
De acordo com o Centers for Disease Control and Prevention (CDC) apesar dos avanços obtidos, nos últimos meses, no desenvolvimento de imunizantes para a COVID-19, algumas perguntas continuam sem respostas, como por exemplo, por quanto tempo as vacinas são capazes de proteger a população da infecção pelo SARS-CoV-2 (CDC, 2021), imunidade híbrida e a necessidade de booster, adicionado ao protocolo inicialmente proposto. Apesar de a maioria dos estudos utilizar os níveis séricos de anticorpos neutralizantes contra o SARS-CoV-2, ainda considera-se desconhecido o nível de anticorpos neutralizantes que garante proteção contra a COVID-19 (CALLAWAY, 2021; BENOTMANE et al., 2021). Por outro lado, embora existam outros mecanismos responsáveis pela resposta imune mediada por células T e B de memória imunológica, Khoury e colaboradores (2021) consideram que a concentração dos anticorpos neutralizantes após contato com o vírus (indivíduos convalescentes soropositivos) e/ou após administração de um imunizante seja capaz de predizer a resposta imune à doença.
ABSTRACT
According to the Centers for Disease Control and Prevention (CDC), despite the advances made in recent months in the development of immunizers for COVID-19, some questions remain unanswered, such as, for example, how long are vaccines able to protect the population from SARS-CoV-2 infection (CDC, 2021), hybrid immunity and the need for a booster, added to the initially proposed protocol. Although most studies use serum levels of neutralizing antibodies against SARS-CoV-2, the level of neutralizing antibodies that guarantee protection against COVID-19 is still unknown (CALLAWAY, 2021; BENOTMANE et al., 2021 ). On the other hand, although there are other mechanisms responsible for the immune response mediated by immune memory T and B cells, Khoury et al (2021) consider that the concentration of neutralizing antibodies after contact with the virus (convalescent seropositive individuals) and/or after administration of an immunizing agent is able to predict the immune response to the disease.
