SCIENCE: SARS-CoV-2 infected macaques are resistant to secondary infections, Qinchuan team reports

!---- The 2019 coronavirus disease (COVID-19) is a severe acute respiratory syndrome caused by coronavirus type 2 (SARS-CoV-2) infection and is now a global epidemicit is still unclear whether cured patients are at risk of reinfectionrecently, Qinchuan and other researchers have created a model of a MACaque infected with SARS-CoV-2, characterized by interstitial pneumonia and the spread of systemic viruses mainly in the respiratory and gastrointestinal tractsin the early recovery phase of the initial SARS-CoV-2 infection, no detectable viral prosthesis, clinical manifestations of viral disease, or hepathological changes were present in macaques re-infected with the same SARS-CoV-2 straincompare body fluid immunity and cellular immunity when the initial infection and the virus re-challenge, and the researchers found significant increases in neutralizing antibodies and immune responsestherefore, the results show that primary SARS-CoV-2 exposure protects macaques from subsequent reinfection
