Effectiveness of the 2010–2011 seasonal influenza vaccine in preventing confirmed influenza hospitalizations in adults: A case–case comparison, case-control study	2012-08-24		.txt	text/plain	4417	226	44	title: Effectiveness of the 2010–2011 seasonal influenza vaccine in preventing confirmed influenza hospitalizations in adults: A case–case comparison, case-control study INTRODUCTION: We estimated influenza vaccine effectiveness (IVE) to prevent laboratory-confirmed influenza-related hospitalizations in patients 18 years old or older during the 2010–2011 influenza season. Using a prospective case-case comparison approach, we have estimated seasonal influenza vaccine effectiveness (IVE) to prevent laboratory confirmed influenza-related hospitalizations in adults. When restricting the comparison, between cases and controls, by the presence of high-risk conditions, the differences that remained significant were age, 23-valent pneumococcal vaccination, and having been vaccinated with the previous or current season influenza vaccines (Table 2) . When restricted to those 60 years old or older, age and influenza vaccination with the previous or current seasonal influenza vaccine remained as significant differences between cases and controls ( Table 2 ).	./cache/cord-293234-ouykx6g5.txt	./txt/cord-293234-ouykx6g5.txt
