MedWire News: Vaccinating college and university students against influenza reduces their risk for influenza-like illness (ILI) and associated impairment of academic performance, according to a study published in the journal Archives of Pediatric and Adolescent Medicine.
“College and university students can experience substantial benefits from influenza vaccinations” say Kristin Nichol (University of Minnesota, Minneapolis, USA) and colleagues.
Their study used student-based measures of ILI including number of days of work or classes missed because of ILI, decreased ability to perform usual tasks, and impaired academic performance.
Over the course of four influenza seasons, researchers enrolled full-time students to the study and asked them to complete online health questionnaires. They pooled data from the 12,975 students between 2002 and 2006 who responded to the baseline questionnaire and at least one follow-up.
The results show that the 30.2% of students who had been vaccinated against influenza were significantly less likely to report ILI, defined as 1 or more day of respiratory illness and fever, in the influenza season than those who had not been immunized (odds ratio [OR]=0.70).
There was also a significant reduction in the number of ILI-associated physician or healthcare provider visits, likelihood of using antibiotics, and poor performance in class or assignments in those who had received the vaccination, compared with their unvaccinated counterparts.
The team found a significant reduction in days of illness and school and work loss due to ILI with vaccination, at an average of half a day less per person vaccinated, compared with unvaccinated students.
Vaccination strains were compared with the predominant circulating viruses each season and even when there was a poor match, as occurred in the 2003–2004 influenza season, vaccination was still associated with a significant reduction in ILI (OR=0.69).
The authors therefore conclude: “These findings underscore the potential benefits of vaccination even when there is not a good match between circulating viruses and vaccine strains.” 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 [标签:content1][标签:content2]
