מחקר חדש – חיסון השפעת לא נותן הגנה
חמישי, 11 במרץ, 2010A new Canadian-led study has added to a simmering scientific dispute over flu-shot campaigns, concluding that immunizing nursing-home workers does nothing to cut the number of confirmed influenza cases among the homes’ elderly residents.
Coming at the end of the largest flu-vaccination campaign in Canadian history, the review of previous studies calls for stepped-up research into alternative, lower-tech ways to combat the virus, such as improved hand washing.
“What troubled us is that [shots] had no effect on laboratory-confirmed influenza,” said Dr. Roger Thomas of the University of Calgary, lead author of the paper published by the respected Cochrane Library.
