Cattle Vaccination Can Cut Risk Of Human E. Coli Infection By 85 Percent

British researchers who analyzed veterinary, human and molecular data to determine the risk of transmitting E. coli from cattle to humans found that vaccinating cattle could have a major impact. E. coli, spread by consuming tainted food and water or by contact with livestock feces, causes severe gastrointestinal illness and even death. The researchers said their data show that vaccinating cattle could cut human sickness cases by nearly 85 percent. Studies that have looked only at the efficacy of currently available vaccines in cattle predict a 50 percent reduction in risk.
