Researchers identify risk factors for SARS-CoV-2 reinfection

A team of scientists from the Capital Medical University and Peking University, China, has recently explored the factors responsible for the reactivation of SARS-CoV-2 infection among individuals who have recently recovered from COVID-19. The findings reveal that individuals with lower lymphocyte count or with two or fewer symptoms during the first COVID-19 episode are at higher risk of recurrent infection.

Rapid mRNA vaccination effectively controls SARS-CoV-2 transmission in long-term care facilities

Vaccine rollouts all over the world are aimed at cutting short the coronavirus disease 2019 (COVID-19) pandemic by inducing antibody-mediated immunity to the virus. A new study, recently released on the medRxiv* preprint server, addresses the successful reduction in viral spread and case incidence among residents of long-term care facilities (LTCF).

Recovered COVID-19 patients may need only a single vaccine dose, suggests study

People who have recovered from COVID-19 had a robust antibody response after the first mRNA vaccine dose, but little immune benefit after the second dose, according to new research from the Penn Institute of Immunology. The findings, published today in Science Immunology, suggest only a single vaccine dose may be needed to produce a sufficient antibody response.

More SARS-CoV-2 variants have emerged from immunocompromised hosts, shows research

A number of SARS-CoV-2 variants have emerged from immunocompromised hosts, research has identified. It is thought that variants of concern - including B.1.1.7, a variant first identified in Kent - were a result of long-term infection in people with a weakened immune system.

Study: Previous COVID-19 infection does not completely protect against reinfection in young people

A past COVID-19 infection does not completely protect against reinfection in young people, according to an observational study of more than 3,000 healthy members of the US Marines Corps most of whom were aged 18-20 years, published in The Lancet Respiratory Medicine journal.
