Chinese vaccine candidate based on inactivated SARS-CoV-2 virus appears safe and induces an immune response in healthy volunteers

Results from an early-phase randomised clinical trial of a Chinese vaccine candidate based on the inactivated whole SARS-CoV-2 virus (CoronaVac) are published in The Lancet Infectious Diseases journal, finding the formulation appears safe and induces an antibody response in healthy volunteers aged 18 to 59 years. Antibody responses could be induced within 28 days of […]

Immunological memory after cured Sars-CoV-2 infection

Until now, it was unclear whether a survived SARS-CoV-2 infection or COVID-19 leads to a persistent immunological memory and thus can protect against a new infection. Several studies had shown that SARS-CoV-2 specific antibodies are only detectable for a few months in many people who have survived COVID-19 and may therefore only provide temporary protection […]

Cytokine storms play a limited role in moderate-to-severe COVID-19

Rather than life-threatening hyperinflammation, most adults with moderate-to-severe COVID-19 have a suppressed viral immune response when compared to adults with another viral respiratory infection, influenza. St. Jude Children’s Research Hospital and Washington University School of Medicine in St. Louis led research that suggests most COVID-19 patients are not candidates for treatment with steroids such as […]
