Scientists develop a novel and potent SARS-CoV-2 RBD-homodimer vaccine

A recent report published in the journal Cell Discovery has described the immunogenicity and protective efficacy of a novel coronavirus disease 2019 (COVID-19) subunit vaccine candidate. The vaccine induces robust immune responses in rodents and non-human primates and protects the animals against severe disease.

Research probes interaction between SARS-CoV-2 and influenza

Researchers from Germany and France tried to determine if epidemiological studies based on co-detection prevalence data can offer a reliable estimation of interactions among respiratory viruses. They designed a simulation study by building on a general epidemiological model of co-circulation of 2 respiratory viruses that cause seasonal epidemics.

Combating the fourth wave of COVID-19 in Ontario

Researchers from Canada recently attempted to project the number of COVID-19 cases and the demand for acute hospital resources for Fall 2021 in a mid-sized southwestern Ontario community. They sought to evaluate if current vaccine coverage and contact reduction levels are sufficient to mitigate a possible 4th wave driven by the Delta variant, or if stricter public health measures need to be reinstituted.

Mu SARS-CoV-2 variant highly resistant to neutralization by convalescent and vaccinated sera

Researchers in Japan have warned that the Mu (B.1.621) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – appears to be highly resistant to neutralization by sera from convalescent or vaccinated individuals.
