Purpose:
To evaluate the rate of seasonal influenza vaccination coverage (IVC) in incident giant cell arteritis (GCA) patients compared with controls.
Methods:
The vaccination rate was estimated from vaccine dispensation. IVC was compared between GCA and their controls using longitudinal multivariate Poisson regression.
Results:
During the influenza campaigns from 2005-2006 to 2010-2011, the IVC rates in the GCA group and the control group ranged from 60.8 to 74.7% vs. 56.6 to 70.4%, respectively. Incident GCA influenza vaccination rate was 20% higher than controls (RR=1.20 ; IC 1.09 to 1.32, P<0.001).
Conclusion:
Although suboptimal, IVC in incident GCA was statistically better than controls.
