New data from Addenbrooke's Hospital in Cambridge suggests that a single dose of the Pfizer BioNTech vaccine can reduce by 75% the number of asymptomatic SARS-CoV-2 infections. This implies that the vaccine could significantly reduce the risk of transmission of the virus from people who are asymptomatic, as well as protecting others from getting ill.
The UK is a world leader in sequencing SARS-CoV-2, the virus that causes COVID-19. Of all the coronavirus genomes that have been sequenced in the world, nearly half have been sequenced by COVID-19 Genomics UK Consortium (Cog-UK). The consortium began life on 4 March 2020 when Sharon Peacock, a professor of public health and microbiology at the University of Cambridge, emailed a handful of scientists and asked for their help.
SARS-CoV-2 mutations similar to those in the B1.1.7 UK variant could arise in cases of chronic infection, where treatment over an extended period can provide the virus multiple opportunities to evolve, say scientists.
Since the start of October, a dedicated team drawn from across the University and its Colleges has been running an innovate programme to screen its students for COVID-19. Getting it up and running in time may have been a Herculean task, but its success has been remarkable.
New research provides important insights into the role played by the immune system in preventing – and in some cases increasing the severity of – COVID-19 symptoms in patients. It also finds clues to why some people experience ‘long COVID’.
The COVID-19 Genomics UK (COG-UK) Consortium has been backed by the Department for Health and Social Care Testing Innovation Fund to expand whole genome sequencing of positive SARS-CoV-2 virus samples to map how COVID-19 spreads and evolves. The £12.2M funding will facilitate the genome sequencing capacity needed to meet the increasing numbers of COVID-19 cases expected in the UK this winter.
In late 2019, a new institute opened on the Cambridge Biomedical Campus. Its timing could not have been better - as the COVID-19 pandemic sent Britain into lockdown several months later, the institute found itself at the heart of the University’s response to this unprecedented challenge.
Vaccine expert Professor Gordon Dougan looks at the challenges of developing and delivering a vaccine against COVID-19.
A Cambridge hospital has piloted the use of combined rapid point-of-care nucleic acid and antibody testing for SARS-CoV-2 infection after researchers at the University of Cambridge showed that this approach was superior to virus detection alone for diagnosing COVID-19 disease.
