Cambridge University kicks off vaccine race to fight all coronaviruses
London: The University of Cambridge on Wednesday confirmed plans to begin trials of a potential new vaccine not only against COVID-19 but all coronaviruses that may spill over from animals to humans in the future.
The new vaccine candidate, DIOS-CoVax2, uses banks of genetic sequences of all known coronaviruses, including those from bats, believed to be the natural hosts of many relatives of human coronaviruses.
A vaccine that clears all trials can then be delivered pain-free without a needle into the skin through a spring-powered jet injection.
Our approach involves 3D computer modelling of the SARS-CoV-2 [Covid-19] virus' structure. It uses information on the virus itself as well as its relatives SARS, MERS and other coronaviruses carried by animals that threaten to spill-over' to humans again to cause future human epidemics, said Professor Jonathan Heeney, head of the Laboratory of Viral Zoonotics at the University of Cambridge, and founder of DIOSynVax a Cambridge spin-out company.
We're looking for chinks in its armour, crucial pieces of the virus that we can use to construct the vaccine to direct the immune response in the right direction. Ultimately we aim to make a vaccine that will not only protect from SARS-CoV-2, but also other related coronaviruses that may spill over from animals to humans, he said.
Prof Heeney said his team's strategy involves targeting those domains of the virus' structure that are absolutely critical for docking with a cell, while avoiding the parts that could make things worse.
What we end up with is a mimic, a synthetic part of the virus minus those non-essential elements that could trigger a bad immune response, he added.
His team have developed libraries of computer-generated antigen structures encoded by synthetic genes that can train the human immune system to target key regions of the virus and to produce beneficial anti-viral responses.
These immune responses include neutralising antibodies, which block virus infection, and T-cells, which remove virus-infected cells.
This so-called laser-specific computer generated approach is able to help avoid the adverse hyper-inflammatory immune responses that can be triggered by recognition of the wrong parts on the coronavirus' surface.
Most research groups have used established approaches to vaccine development because of the urgent need to tackle the pandemic. We all hope the current clinical trials have a positive outcome, but even successful vaccines are likely to have their limitations they may be unsuitable for vulnerable people, and we do not know how long their effects will last for, for example, said Dr Rebecca Kinsley, Chief Operating Officer of DIOSynVax and a postdoctoral researcher at the University of Cambridge.
Our approach using synthetic DNA to deliver custom designed, immune selected vaccine antigens is revolutionary and is ideal for complex viruses such as coronavirus. If successful, it will result in a vaccine that should be safe for widespread use and that can be manufactured and distributed at low cost, she said.
DIOS-CoVax2, which hopes to go into human trials by later this year, is the latest vaccine candidate to be backed by the UK government with 1.9 million pounds in funding as part of a collaboration between DIOSynVax, which is contributing an additional 400,000 pounds to the trial, the University of Cambridge and the University Hospital Southampton NHS Foundation Trust.
The team say their proposed new vaccine can be freeze-dried as a powder and is therefore heat stable, meaning that it does not need to be cold-stored. This makes transport and storage much more straightforward, particularly important in low and middle income countries, and it can be delivered through PharmaJet Tropis intradermal Needle-free Injection System, which delivers the vaccine in less than a 1/10th of a second jet injection.
Professor Saul Faust, Director of the NIHR Southampton Clinical Research Facility, said: It is especially exciting that the clinical trial will test giving the vaccine through people's skin using a device without any needles as together with stable DNA vaccine technology this could be a major breakthrough in being able to give a future vaccine to huge numbers of people across the world.
The news comes as the University of Oxford revealed that its trials of a potential vaccine against COVID-19 being developed with AstraZeneca could be put before regulators this year if scientists are able to gather enough data.
The Oxford vaccine, as it is commonly known, showed early promise in the first human trial when it produced an immune response, underlining its position as one of the leading candidates in the race to help vaccinate humans against the deadly novel coronavirus.

3 Indians arrested in Canada for shooting outside home
Ottawa (PTI): Three Indian nationals have been arrested by Canadian police on an anti-extortion patrol and charged after bullets were fired at a home.
Harjot Singh (21), Taranveer Singh (19) and Dayajeet Singh Billing (21) face one count each of discharging a firearm, and all have been remanded in custody until Thursday, the Surrey Police Service (SPS) said in a statement on Monday.
The suspects were arrested by patrol officers after an early morning report of shots fired and a small fire outside a home in Surrey's Crescent Beach neighbourhood, the LakelandToday reported.
On February 1, 2026, the SPS members were patrolling in Surrey’s Crescent Beach neighbourhood when reports came in of shots being fired and a small fire outside a residence near Crescent Road and 132 Street.
The three accused were arrested by SPS officers a short time later, the statement said.
SPS’s Major Crime Section took over the investigation, and the three men have now been charged with Criminal Code offences, it said.
All three have been charged with one count each of discharging a firearm into a place contrary to section 244.2(1)(a) of the Criminal Code.
The investigation is ongoing, and additional charges may be forthcoming. All three have been remanded in custody until February 5, 2026.
The SPS has confirmed they are all foreign nationals and has engaged the Canada Border Services Agency, it said.
One of the suspects suffered injuries, including two black eyes, the media report said.
Surrey police Staff Sgt. Lindsey Houghton said on Monday that the suspect had refused to comply with instructions to get out of the ride-share vehicle and started to "actively resist."
"As we were trained, he was taken to the ground and safely handcuffed," said Houghton.
A second suspect with a black eye was also injured in the arrest after refusing to comply, Houghton said.
The arresting officers were part of Project Assurance, an initiative that patrols neighbourhoods that have been targeted by extortion violence.
Houghton said the Canada Border Services Agency (CBSA) is also involved because the men are foreign nationals, and the trio may face additional charges.
It's not clear if the men are in the country on tourist visas, a study permit, or a work permit, but Houghton said CBSA has started its own investigation into the men's status.
Surrey has seen a number of shootings at homes and businesses over the last several months, but there's been an escalation since the new year.
