Among persons with heart disease, coverage for 2012–2013 season was 50.9% (95% CI, 48.2%–53.6%) for persons aged 50 to 64 years
Based on data vs IMHO ... the influenza vaccination coverage among persons with heart disease - for persons aged 50 to 64 years: was flat (49.2% vs 50.9%) from 1999–2000 to 2012-2013 - for persons aged 65 years and older: meanwhile no data available (?) for the recent years, due to: > high basis: 76.7% > flat coverage (62.7% vs 65.3%) for overall population (aged 65 years and older) more likely, it was flat (or small increase) also ... the potential, maximum increase is ABS 23.3%, relative 30% ... to reach 100% coverage ... not likely scenario
As 32% of R-IT study locations are in non-Westen countries and (based on ANCHOR: 38.9%) the expected % of ≥65 years of age is app. 40% ... it isn't likely that the Flu shot / the "big push" of it has any effect on R-IT event rate.
