COVID-19 vaccine candidate stimulates neutralising antibody production in vivo
The novel haptenised SARS-CoV-2 s-Spike vaccine, BVX-0320, stimulated mice to create neutralising antibodies that were able to reduce SARS-CoV-2 plaques in a neutralisation test.
news
Majority retain COVID-19 antibodies for six months after infection
A study has shown that 88 percent of people infected by COVID-19 were able to produce SARS-CoV-2 antibodies after six months.
news
Novel AI tool takes a DeepCE dive into potential drugs for COVID-19
A new phenotype-based compound screening technology, called DeepCE, identified 10 compounds that could be repurposed for COVID-19.
news
N439K variant of SARS-CoV-2 is resistant to some neutralising antibodies, shows study
The N439K mutation improves the interaction between SARS-CoV-2 Spike protein and the viral receptor ACE2 and eludes antibody-mediated immunity, say investigators.
news
UK offers genomics expertise to identify new SARS-CoV-2 variants
The UK Government has said genomics expertise will be offered to countries around the world to identify new variants of SARS-CoV-2.
news
T cells target broad range of SARS-CoV-2 epitopes, study shows
A study has found that T cells combat SARS-CoV-2 by targeting many sites on the coronavirus, not just the Spike protein.
news
New database to track neurological symptoms of COVID-19
NeuroCOVID will be a resource of clinical information and biospecimens from people who experience neurological problems associated with SARS-CoV-2 infection.
news
Biomarker in blood could determine severity of COVID-19
A study has shown that patients with severe COVID-19 have significantly elevated levels of M-MDSCs in their blood compared with healthy individuals.
news
Novel antibody candidate could offer pan-coronavirus protection
The lead candidate, ADG2, was able to neutralise SARS-CoV and various strains of SARS-CoV-2, including those that are resistant to currently available antibody treatments.
news
Rhesus macaques with SARS-CoV-2 develop promising immune response
A study has shown that the immune response of rhesus macaques with SARS-CoV-2 could be reproduced with a vaccine.
news
SARS-CoV-2 triggers antibodies from previous coronavirus infections
A new study has shown that previous coronavirus infection may contribute to the immune response of patients infected with SARS-CoV-2.
news
T-cell exhaustion may limit long-term immunity in COVID-19 patients
Researchers suggest patients who develop mild COVID-19 may not be able to fight reinfection very effectively because their CD8+ T cells show signs of exhaustion.
news
Severe symptoms of COVID-19 are caused by brain infection in mice, finds study
Researchers found that SARS-CoV-2 persists in the brain after it is cleared in the lungs and concluded the severest and longest lasting symptoms of COVID-19 may be caused by brain infection.
news
Recovered COVID-19 patients may be protected, but they could still transmit the virus
According to a Public Health England study, prior SARS-CoV-2 infection provides 83 percent protection against reinfection but may not stop individuals spreading COVID-19.
