【科普】大学生接种流感疫苗获得“实实在在的好处”
NEW YORK (Reuters Health) Dec 01 - College and university students who receive influenza vaccinations can expect reduced illness, less health care use, fewer episodes of school absenteeism, and a lower risk for impaired academic performance, physicians at the University of Minnesota have found.
"Cold/flu/sore throat has been identified as the second leading cause of impediments to academic performance among college and university students across the United States," Dr. Kristin L. Nichol and colleagues in Minneapolis report in the Archives of Pediatrics and Adolescent Medicine for December.
Dr. Nichol's team studied close to 13,000 students at the University of Minnesota during four separate flu seasons between 2002 and 2006, and from St. Olaf College in Northfield for the 2005-2006 flu season. Data were collected by Internet-based surveys completed by full-time students.
Overall, 30% of students were vaccinated, the researchers report, and 24% experienced at least one influenza-like illness during months when influenza was circulating.
The likelihood of influenza-like illness during the flu seasons was significantly reduced among vaccinees (adjusted odds ratio, 0.70). A similar reduction was observed even during the 2003-2004 season when there was a poor match between the predominant circulating viruses and vaccine strains.
"Vaccination was also associated with significant reductions in influenza-like illness-associated provider visits, antibiotic use, impaired school performance, numbers of days of missed class, and illness during the influenza," the authors report.
