Scientists have developed a universal vaccine using artificial intelligence that can stop future pandemics and protect against mutations.
Scientists have presented a new universal vaccine that could change the approach to combating future pandemics. Artificial intelligence was actively used in its development for the first time, helping to identify the most resilient elements of coronaviruses. Researchers hope that such a drug will be able to protect not only against existing viruses but also against those that have not yet emerged.
Researchers have radically changed the approach to vaccine creation by entrusting artificial intelligence with the analysis of genetic data from thousands of different strains of coronaviruses. Using machine learning methods, they were able to identify the most stable regions of the viruses—fragments that hardly change during mutations. It is these regions that the immune system now targets after vaccination.
Scientists from the University of Cambridge and the biotechnology company DIOSynVax developed a drug called Sarbeco. The vaccine combines key features of the entire family of coronaviruses, allowing the body to recognize not only known viruses but also potentially those that do not yet exist in nature.
Professor Jonathan Gini from the Viral Zoonoses Laboratory explained the logic behind the development:
"The Covid pandemic taught us how quickly we can create vaccines, but we are still using an old paradigm. It’s about creating one vaccine that will hit everyone, depending on their relationships."
Results of the First Clinical Trials in Humans
The effectiveness of the new approach has already begun to be tested in practice. The first phase of clinical trials involved 49 healthy volunteers aged 18 to 50. The study was conducted in Cambridge and Southampton.
The results confirmed the safety of the drug. Moreover, the vaccine demonstrated the ability to generate an immune response not only against SARS-CoV-2 but also against a number of bat coronaviruses.
According to scientists, this is particularly important for preventing new outbreaks of diseases that can be transmitted from animals to humans.
The next stage of research will be significantly larger. The second phase plans to involve more than 200 volunteers, which will provide additional data on the effectiveness and reliability of protection.
Needle-Free Vaccination: How the New Technology Works
The developers offer not only a new type of vaccine but also an innovative method of administration.
Instead of traditional syringes, a microfluidic jet is used—a super-thin stream of liquid under very high pressure. This jet penetrates through the skin surface and delivers the drug directly into the cells in a fraction of a second.
According to specialists, this method has several advantages:
- absence of pain and discomfort associated with injections;
- rapid penetration of the DNA vaccine into cells;
- reduced risk of tissue damage;
- more convenient mass vaccination.
The End of Reactive Medicine
Today, medicine largely operates on the principle of responding to already emerging threats: vaccines begin to be developed after the appearance and spread of a new virus.
Professor Sol Faust from the University of Southampton believes this approach is not sufficiently effective.
"Viruses such as influenza, coronaviruses, and the Ebola virus group are constantly evolving, and by the time vaccines are implemented, they may be poorly matched—the current 'reactive' vaccination system struggles to keep up with changes," said Faust.
In his opinion, next-generation universal vaccines can give humanity a strategic advantage over rapidly changing pathogens.
The new technology is designed not only to protect against many existing variants of viruses simultaneously but also against related pathogens that have not yet emerged or begun to spread among humans.
"If we can develop and clinically refine this new class of vaccines before a virus outbreak, we could save millions of lives, avoid lockdowns, and preserve the economy," emphasized the professor.
Researchers believe that such an approach could be an important step toward preventing future pandemics and allow a shift from constantly dealing with consequences to preventing them even before a global threat arises.
The creation of the universal vaccine Sarbeco demonstrates how artificial intelligence is beginning to change modern medicine. If further trials confirm the effectiveness of the drug, humanity may gain a tool to protect not only against current coronaviruses but also against potential viruses of the future, which would be one of the most significant achievements in the field of infectious disease prevention in recent decades.
