A bivalent Adenovirus-Vectored Vaccine induces a measurable humoral response, but does not protect cynomolgus macaques against a lethal challenge with Sudan virus

This study evaluates a bivalent Adenovirus-Vectored Vaccine in cynomolgus macaques against Sudan virus, finding it induces humoral responses but does not confer protection against lethal challenge.

SARS-CoV-2 Omicron BA.1 and BA.2 are attenuated in rhesus macaques as compared to Delta

This study compares disease severity and viral load in rhesus macaques infected with SARS-CoV-2 Delta, Omicron BA.1, and BA.2 variants, finding Omicron variants cause less severe disease with lower viral loads.

Combined Molnupiravir and Nirmatrelvir Treatment Improves the Inhibitory Effect on SARS-CoV-2 in Rhesus Macaques

The combination of molnupiravir and nirmatrelvir inhibits SARS-CoV-2 replication and shedding more effectively than individual treatments in the rhesus macaque model.

Molnupiravir (MK-4482) is efficacious against Omicron and other SARS-CoV-2 variants in the Syrian hamster COVID-19 model

MK-4482 inhibits replication of multiple SARS-CoV-2 variants of concern, including Omicron, in the Syrian hamster model.

SARS-CoV2 variant-specific replicating RNA vaccines protect from disease and pathology and reduce viral shedding following challenge with heterologous SARS-CoV2 variants of concern

This study evaluates a replicating RNA vaccine against SARS-CoV-2 variants, showing protection from disease and reduced viral shedding after heterologous challenge.

Genetically diverse mouse models of SARS-CoV-2 infection reproduce clinical variation in type I interferon and cytokine responses in COVID-19

The paper uses genetically diverse mice to model varied innate immune responses to SARS-CoV-2 infection, showing differences in survival, viral replication, and cytokine profiles.

Age-related differences in immune dynamics during SARS-CoV-2 infection in rhesus macaques

This study compares immune dynamics in young and old rhesus macaques infected with SARS-CoV-2, finding age-related differences in post-acute immune responses but similar acute disease outcomes.

Increased aerosol transmission for B.1.1.7 (alpha variant) over lineage A variant of SARS-CoV-2

This study shows that the B.1.1.7 variant of SARS-CoV-2 is more efficiently transmitted via aerosols than lineage A in Syrian hamsters.

Western diet increases COVID-19 disease severity in the Syrian hamster

This study shows that a Western diet worsens COVID-19 outcomes in Syrian hamsters by increasing weight loss, lung damage, and systemic inflammation.

UK B.1.1.7 variant exhibits increased respiratory replication and shedding in nonhuman primates

This study compares the respiratory replication and shedding of SARS-CoV-2 D614G and B.1.1.7 variants in African green monkeys, finding increased respiratory replication for B.1.1.7 but no disease enhancement.

Prior aerosol infection with lineage A SARS-CoV-2 variant protects hamsters from disease, but not reinfection with B.1.351 SARS-CoV-2 variant

Recovery from acute SARS-CoV-2 infection and development of anamnestic immune responses in T cell-depleted rhesus macaques

This study shows that T cell depletion in rhesus macaques does not cause severe SARS-CoV-2 disease but delays viral clearance, and T cells are not essential for immunological memory or protection against re-infection.

SARS-CoV-2 infection dynamics in lungs of African green monkeys

This study examines SARS-CoV-2 infection dynamics in African green monkeys, showing viral replication in the lower respiratory tract and macrophage involvement in inflammation.

K18-hACE2 mice develop respiratory disease resembling severe COVID-19

This paper shows that K18-hACE2 mice develop severe respiratory disease upon SARS-CoV-2 infection, resembling human severe COVID-19 with lung pathology and systemic inflammation.
