Systems immunology of transcriptional responses to viral infection identifies conserved antiviral pathways across macaques and humans

The paper identifies conserved antiviral pathways across macaques and humans using transcriptomic data from viral infections, showing shared and virus-specific responses that inform pandemic preparedness.

Durable immunity to SARS-CoV-2 in both lower and upper airways achieved with a gorilla adenovirus (GRAd) S-2P vaccine in non-human primates

This study shows a gorilla adenovirus-based vaccine provides durable immunity against SARS-CoV-2 in both airways of non-human primates, with enhanced protection from aerosol delivery and prime-boost regimens.

Mucosal Adenoviral-vectored Vaccine Boosting Durably Prevents XBB.1.16 Infection in Nonhuman Primates

This study shows that mucosal adenoviral-vectored vaccines provide durable protection against XBB.1.16 infection in nonhuman primates, outperforming intramuscular boosting in reducing virus replication in both upper and lower airways.

RBD-based high affinity ACE2 antagonist limits SARS-CoV-2 replication in upper and lower airways

RBD-62, a high-affinity ACE2 antagonist, limits SARS-CoV-2 replication in both upper and lower airways in rhesus macaques without blocking memory responses or causing anti-drug immunity.

Modulation of type I interferon responses potently inhibits SARS-CoV-2 replication and inflammation in rhesus macaques

This study shows that modulating type I interferon responses in rhesus macaques reduces SARS-CoV-2 viral load and inflammation, suggesting a potential therapeutic strategy for severe COVID-19.

Intranasal Immunization with a Proteosome-Adjuvanted SARS-CoV2 Spike Protein-Based Vaccine is Immunogenic and Efficacious in Mice & Hamsters

This study evaluates an intranasal vaccine formulation containing a proteosome-adjuvanted SARS-CoV-2 Spike protein, showing immunogenicity and efficacy in mice and hamsters against multiple variants.

mRNA-1273 or mRNA-Omicron boost in vaccinated macaques elicits comparable B cell expansion, neutralizing antibodies and protection against Omicron

This study compares B cell responses and protection against Omicron after boosting vaccinated macaques with mRNA-1273 or mRNA-Omicron vaccines, finding comparable immunity and protection.

Breadth of SARS-CoV-2 Neutralization and Protection Induced by a Nanoparticle Vaccine

This study shows a nanoparticle vaccine induces broad neutralizing antibodies against multiple SARS-CoV-2 variants and protects non-human primates and mice from viral challenges.

mRNA-1273 and BNT162b2 mRNA vaccines have reduced neutralizing activity against the SARS-CoV-2 Omicron variant

This study evaluates the neutralizing activity of mRNA vaccines against the SARS-CoV-2 Omicron variant, showing reduced efficacy after the second dose but improved responses following a third dose.

Protection from SARS-CoV-2 Delta one year after mRNA-1273 vaccination in nonhuman primates is coincident with an anamnestic antibody response in the lower airway

This study shows that mRNA-1273 vaccine protection against SARS-CoV-2 Delta in nonhuman primates persists for one year but is delayed and relies on anamnestic antibody responses in the lower airway.

Protection against SARS-CoV-2 Beta Variant in mRNA-1273 Boosted Nonhuman Primates

mRNA-1273 boosted nonhuman primates show increased neutralizing antibody responses and protection against SARS-CoV-2 beta variant infection.

Evaluation of mRNA-1273 against SARS-CoV-2 B.1.351 Infection in Nonhuman Primates

This study evaluates mRNA-1273 vaccine efficacy against SARS-CoV-2 B.1.351 in nonhuman primates, finding that two doses significantly reduce viral replication in the airways.

Infection and vaccine-induced neutralizing antibody responses to the SARS-CoV-2 B.1.617.1 variant

This study assesses neutralizing antibody responses to the SARS-CoV-2 B.1.617.1 variant in convalescent and vaccinated individuals, finding it is 6.8-fold more resistant but still neutralizable.

Immune Correlates of Protection by mRNA-1273 Immunization against SARS-CoV-2 Infection in Nonhuman Primates

This study shows that mRNA-1273 vaccine-induced antibody responses correlate with protection against SARS-CoV-2 infection in nonhuman primates.

Vaccination with SARS-CoV-2 Spike Protein and AS03 Adjuvant Induces Rapid Anamnestic Antibodies in the Lung and Protects Against Virus Challenge in Nonhuman Primates

This study shows that an AS03-adjuvanted SARS-CoV-2 spike protein vaccine induces strong antibody responses and protects nonhuman primates from viral challenge.

SARS-CoV-2 vaccination induces neutralizing antibodies against pandemic and pre-emergent SARS-related coronaviruses in monkeys

This study shows that SARS-CoV-2 vaccines induce neutralizing antibodies against SARS-CoV-1, SARS-CoV-2, and batCoVs in monkeys.

Strength of T cell signaling regulates HIV-1 replication and establishment of latency

This study shows that strong T cell signaling promotes HIV-1 expression and inducible latency, while weak signaling leads to stable, refractory latency.
