Study characterizes early chains and patterns of COVID-19 transmission in France

By using data from epidemiological investigations and contact-tracing efforts during the initial phase of the coronavirus disease (COVID-19) epidemic in France, researchers were able to appraise secondary clinical attack rates and factors associated with the risk of a contact becoming a case. Their findings are currently available in a medRxiv preprint paper.

Mosaic RBD nanoparticles elicit neutralizing antibodies against SARS-CoV-2

The researchers show that the mice immunized with homotypic or mosaic nanoparticles produced broad binding and neutralizing responses, in contrast to plasma antibodies elicited in humans by SARS-CoV-2 infection. The RBD nanoparticles induced cross-reactive IgG responses in the immunized mice.

New findings support current and planned clinical trials of Janssen SARS-CoV-2 vaccine

Researchers from the United States and The Netherlands have conducted a pre-clinical study supporting the initiation of a Phase 3 trial to test a two-dose regimen of the Janssen Ad26.COV2.S vaccine candidate among adult and elderly individuals.

Detectable SARS-CoV-2 antibodies 120 days post-infection in Chicago case study

In a recent study, a team of researchers at Northwestern University, USA, had found that nearly 20 percent seroprevalence in the United States metropolitan site, Chicago, over the summer, during a period when lockdown restrictions were eased. They found that three-quarters of seropositive individuals retained detectable antibodies for at least 120 days or four months.

"Escape mutations" could help SARS-CoV-2 evade immune attack

Researchers in the United States have identified mutations within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – that can reduce antibody binding to the virus, potentially mediating its escape from immune attack.
