A jab that stops the spread of a range of coronaviruses has been created by scientists.
It could end pandemics caused by zoonotic diseases that emerge in animals.
In experiments, the vaccine halted five different types in their tracks – including Covid-19.
Lead author Professor Tomohiro Kurosaki, of Osaka University, said: “Prior coronavirus epidemics such as SARS-CoV-1 and MERS-CoV have occurred due to zoonotic coronaviruses crossing the species barrier.
“The potential for the emergence of similar viruses poses a significant threat to global public health, even in the face of effective vaccines for current viruses.”
The study in the Journal of Experimental Medicine opens the door to a next-generation jab that will reduce the risk of pandemics.
