Vaccines currently being developed for COVID-19 should not be affected by recent mutations in the virus, according to a new study involving a University of York virologist.

Most vaccines under development worldwide have been modelled on the original 'D-strain' of the virus, which were more common amongst sequences published early in the pandemic.

People who survive serious COVID-19 infections have long-lasting immune responses against the virus, according to a new study led by researchers at Massachusetts General Hospital (MGH). The study, published in Science Immunology, offers hope that people infected with the virus will develop lasting protection against reinfection.

A new study by Simon Fraser University (SFU) researchers has found clear evidence that wearing a mask can have a significant impact on the spread of COVID-19. The researchers, from SFU's Department of Economics, have determined that mask mandates are associated with a 25 per cent or larger weekly reduction in COVID-19 cases.

Being previously infected with a coronaviruses that cause the "common cold" may decrease the severity of severe acute respiratory syndrome coronavirus (SARS-CoV-2) infections, according to results of a new study. Led by researchers at Boston Medical Center and Boston University School of Medicine, the study also demonstrates that the immunity built up from previous non-SARS-CoV-2 coronavirus infections does not prevent individuals from getting COVID-19.

CureVac N.V. (Nasdaq: CVAC), a clinical-stage biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid ("mRNA"), announced that the first participant has been dosed in a Phase 2a clinical trial of its COVID-19 vaccine candidate, CVnCoV.

Researchers at Uppsala University have found that an effective way of treating the coronavirus behind the 2003 SARS epidemic also works on the closely related SARS-CoV-2 virus, the culprit in the ongoing COVID-19 pandemic. The substance concerned is nitric oxide (NO), a compound with antiviral properties that is produced by the body itself. The study is published in the journal Redox Biology.

Four out of five people experiencing the recent loss of smell and/or taste tested positive for COVID-19 antibodies - and of those who tested positive, 40 percent did not have cough or fever, reports a new study in PLOS Medicine by Prof. Rachel Batterham at University College London and colleagues.
