Synthetic vaccine made without virus

British scientists have developed a new method to create an entirely synthetic vaccine which doesn't rely on using live infectious virus, meaning it is much safer, BBC reported.

What's more the prototype vaccine they have created, for the animal disease foot-and-mouth, has been engineered to make it more stable.

That means it can be kept out of the fridge for many hours before returning to the cold chain - overcoming one of the major hurdles in administering vaccines in the developing world.

The research, published in the journal PLOS pathogens, was a collaboration between scientists at Oxford and Reading Universities, the Pirbright Institute, and the UK's national synchrotron facility, the Diamond Light Source near Oxford.

Diamond is a particle accelerator which sends electrons round a giant magnetic ring at near light speeds.
