Washington:A vaccine, which is being created by drug company Sanofi Pasteur, has now reached phase three trials.
The company has claimed that the vaccine could wipe out almost all cases of the killer superbug C diff in hospitals, the Mirror reported.
Currently, there are more than 15,000 cases of the disease a year, which is causing 1,500 deaths mainly in hospitals, but also in care homes for the elderly.
The vaccine is going to be tested on 1,800 UK patients at nine hospitals as part of 15,000 strong world trial by the drug company Sanofi-Pasteur.
Earlier trials of the vaccine have shown it to be safe and effective against the stomach superbug and researchers are hoping that it may become available in as little as three years.
