July 17, 2012 - A new study finds the HPV vaccine is lowering infection rates, even among young women who are not vaccinated. Doctors at Cincinnati Children's Hospital say infections dropped 69 percent in vaccinated women and 49 percent in unvaccinated women. Researchers say this is the first study to show so called "herd protection" which happens when a large number of people are immunized against a contagious disease. More than 35 million people were vaccinated in recent years for the human papillomavirus.
Also, reducing stress could help patients with multiple sclerosis. Researchers at Northwestern studied 121 MS patients and found those who took part in a weekly stress management program prevented new brain lesions from developing. Brain lesions are a marker of the disease and usually form before a flare-up of symptoms like vision loss or pain.
