Majority of T-cell targets not on COVID-19 Spike protein, study finds
Research has shown T cells taken from patients with COVID-19 target the same three to eight immunodominant epitopes - most of which are not on the Spike protein.
news
Team redesigns COVID-19 Spike protein for more stable vaccines
Researchers have modified the COVID-19 Spike protein for use in vaccines, which produces up to 10 times more protein than that of an earlier synthetic versions.
news
Nanoparticle COVID-19 vaccine elicits immune response in pre-clinical studies
The vaccine candidate repRNA-CoV2S elicited both antibody and T cell responses after just two injections in mice and macaques.
news
Most antibodies targeting SARS-CoV-2 use specific immunoglobulin subtype
Researchers reveal IgHV3-53 is the most common immunoglobulin mutation used to target the receptor binding domain on the SARS-CoV-2 spike protein.

Prophylactics for COVID-19 – known and unknown
This article outlines the ideal scientific research that should be conducted to design a prophylactic to combat COVID-19.
news
Macaques develop short-term immunity to SARS-CoV-2
Researchers experimenting on macaques reveal they were protected against reinfection up to a month after the initial exposure to SARS-CoV-2.
news
MMR vaccine could protect against COVID-19 sepsis, paper says
Researchers have suggested that the MMR live attenuated vaccine could be used to provide non-specific protection to patients against sepsis associated with COVID-19.
news
SARS-CoV-2 immunodominant epitopes identified as vaccine candidates
Researchers have analysed the SARS-CoV-2 proteome to reveal seven promising immunodominant epitopes that could aid in the development of a COVID-19 vaccine.
news
Computational approach identifies novel COVID-19 vaccine targets
Researchers used computational tools to identify regions of the SARS-CoV-2 virus that could potentially provide a safe and long-term immune response.
article
Using scientific literature to aid the development of a safe and effective COVID-19 vaccine
Researchers in the US describe how they utilised previously published scientific literature to guide the design of their potential COVID-19 vaccine.
news
White blood cells as a novel early indicator of vaccine efficacy
Researchers demonstrate that a subpopulation of circulating white blood cells can act as an early indicator of vaccine efficacy, with potential implications for COVID-19 drug development.
news
Protective immunity to SARS-CoV-2 shown in non-human primates
Macaques were protected against SARS-CoV-2 infection both after an initial infection and vaccination with a prototype vaccine, researchers suggest humans could respond similarly.
news
Analysis of immune response to SARS-CoV-2 gives hope for COVID-19 vaccines
A detailed analysis of the body's immune response to COVID-19 has revealed that it can recognise SARS-CoV-2 in many ways, meaning vaccines can be used to stop the spread of the virus.
news
Oxford University and NIH COVID-19 vaccine shows success in rhesus macaques
A vaccine currently in Phase I clinical trials was effective at inducing immune responses against SARS-CoV-2 in mice and rhesus macaques.
