A newly developed vaccine might serve as a useful weapon against the drug-resistant superbug MRSA, researchers say. Tests in mice have shown that the vaccine can protect against multiple types of MRSA, which can cause fatal infections in humans.
Experts say the discovery of a broadly effective vaccine is especially important as more infectious MRSA strains have recently emerged. They also stress that patients with compromised immune systems face an ever-increasing risk of acquiring MRSA, or methicillin-resistant Staphylococcus aureus, while in hospital.
Olaf Schneewind at the University of Chicago, Illinois, US and his colleagues came up with the new vaccine by identifying the bits of genetic code that eight different S. aureus strains share. This genetic analysis revealed 19 proteins that can be found on the cell surface of all eight strains.
That is a fascinating study. I wonder if they would also use the vaccine on those who already have this type of infection in hopes that they will develop antibodies to fight their infection. Your article only speaks to prophylatic use preop.
