Adenovirus type 5 SARS-CoV-2 vaccines delivered orally or intranasally reduced disease severity and transmission in a hamster model

Stephanie N. Langel et al.

Summary: Vaccination through oral or intranasal routes can generate strong antibody responses, reduce viral load in the nose and lungs, and mitigate lung pathology caused by SARS-CoV-2. Mucosally vaccinated hamsters transmitted fewer viruses with less severity to naive hamsters, suggesting that mucosal immunization can reduce viral transmission. In a clinical trial, the same platform also induced mucosal cross-reactive antibody responses.

A broadly neutralizing antibody protects Syrian hamsters against SARS-CoV-2 Omicron challenge

Biao Zhou et al.

Summary: Here, researchers successfully screened and isolated a broadly neutralizing antibody ZCB11 that can neutralize all variants of concern of SARS-CoV-2, showing particularly potent activity against the Omicron variant. Further studies demonstrated that ZCB11 predominantly interacts with the receptor-binding domain of the Omicron variant, blocking ACE2 binding. Prophylactic or therapeutic administration of ZCB11 protected against lung infection in animal models challenged with the Omicron variant.

Development of a coronavirus disease 2019 nonhuman primate model using airborne exposure

Sara C. Johnston et al.

Summary: Airborne transmission of SARS-CoV-2 is found to be a prevalent route of human exposure. In a study comparing African green monkeys, rhesus macaques, and cynomolgus macaques exposed to the virus, respiratory abnormalities and viral shedding were observed in all animals. Fever was noted in cynomolgus macaques, while African green monkeys and rhesus macaques experienced thrombocytopenia. The findings suggest that macaques, in addition to African green monkeys, can serve as successful natural transmission models for evaluating medical countermeasures.

Summary: Transmission of SARS-CoV-2 from humans to farmed mink and back raises concerns of genetic variants with potential increased threat to human health. Mutations in the spike protein of SARS-CoV-2 from mink allow efficient entry into human cells and inhibition by ACE2, while mutation Y453F reduces neutralization by certain antibodies authorized for COVID-19 therapy. Antibody responses induced by infection or specific treatments might not offer adequate protection against SARS-CoV-2 variants from mink.
