A vaccine to guard against hospital superbug MRSA is a step closer, according to scientists. US researchers have developed a vaccine that protected mice from four potentially deadly strains of MRSA.

The team looked for a vaccine using a technique called “reverse vaccinology”, which builds on recent genetics advances.

It involved sifting through the genome of Staphylococcus aureus to hunt for proteins on the microbe that might spark the body’s immune system into action, producing protection against the bacteria.

The team identified four proteins that prompted a strong immune response, making them good targets for vaccines.
