Researchers define immune determinants of protection against SARS-CoV-2 in mice

Researchers in the United States have conducted a preclinical study defining the roles that different arms of the immune system play in fighting primary infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as reinfection and infection following SARS-CoV-2 vaccination.

Pfizer-BioNTech and Sinovac vaccines boost SARS-CoV-2 neutralizing responses

Researchers in the United States and Chile have provided preliminary evidence that individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – mount a robust neutralizing antibody response against the virus that can be significantly boosted by two doses of Sinovac Biotech’s CoronaVac vaccine or one dose of Pfizer-BioNTech’s BNT162b2 vaccine.

Intranasal COVID-19 therapeutic shows promise in preclinical trials

Researchers from the US and Denmark recently described a novel therapeutic option that targets the SARS-CoV-2 ribonucleic acid (RNA) using locked nucleic acid antisense oligonucleotides (LNA ASOs). They identified an LNA ASO that binds to the 5’ leader sequence of SARS-CoV-2 ORF1a/b. This disrupts a highly conserved stem-loop structure with nanomolar efficacy and inhibits viral replication in host cells.

COVID-19 death rate for people with IDD is higher across the U.S.

The COVID-19 death rate for people with intellectual and developmental disabilities (IDD) is higher than the general population in several states across the U.S., according to a new study published in Disability and Health Journal.

Resuming global childhood vaccination campaigns during the COVID-19 pandemic

New research published on the medRxiv* preprint server suggests childhood vaccination to prevent other infectious diseases has plummeted during the pandemic. The decrease appears to stem from the suspension of health campaigns promoting immunization and the risk of catching the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19).

Does cross-immunity exist between SARS-CoV-2 B.1.1.28 and P.1 variants?

A team of researchers recently cross-tested severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies to assess their neutralization activity against different variants. The team recently released their findings as a preprint on the medRxiv* server.

Plant-produced COVID-19 vaccine shows potent immunogenic profile in humans

An interim report on a phase 2 clinical trial indicates both the safety and efficacy of a plant-produced virus-like particle vaccine candidate against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The vaccine candidate has shown an acceptable safety profile and high potency in inducing humoral and cellular immune responses in adults (18 – 64 years) and elderly (65 years and above) individuals. The report is currently available on the medRxiv* preprint server.
