CDC: Flu Vaccine Only 18% Effective
The flu vaccine is even less effective than health officials thought against the strain of influenza making most people sick this season. Getting the vaccine has reduced the risk of illness from the H3N2 strain of flu by only 18%, a new report says. The report comes from the U.S. Centers for Disease Control and Prevention (CDC). Officials said earlier in the season that the vaccine was about 23% effective. Among children, the vaccine offers even less protection, about 15%, the CDC said. The nasal spray vaccine may not protect children at all. One particular strain of H3N2 is causing most cases of flu in the United States so far this season. This strain was first seen in March 2014, the CDC said. That was too late to be included in the vaccine for this year. In most years, the flu vaccine is 50% to 70% effective. HealthDay News wrote about the CDC report February 26.Â

Wider Spread for Hospital-Linked Infections
In a recent year, more than 450,000 Americans had a type of severe diarrhea that most often occurs in health-care facilities. But one-third of them had not been in a hospital or nursing home recently, a study found. About 29,000 of those who were infected died. The diarrhea was caused by Clostridium difficile (C. diff) bacteria. These infections are hard to cure. Researchers used information from 2011. They looked at C. diff infections in 10 states. Two-thirds of them occurred in hospitals and nursing homes. The other one-third occurred in the community. But 80% of the community patients had been to see a doctor or dentist recently. Most of them received antibiotics. C. diff bacteria are most likely to grow and produce toxins when antibiotics kill the normal, harmless bacteria in the intestine. The New England Journal of Medicine published the study.
