Denominators for estimation of influenza vaccine coverage among high risk persons aged 15 to 64 years.
OBJECTIVE
To propose and demonstrate a method for the estimation of the denominators required for the calculation of vaccine coverage for persons aged 15 to 64 years who are recommended to receive influenza vaccine.


METHODS
The age-sex-specific proportions of persons aged 15 to 64 years who self reported having relevant chronic health conditions were estimated from Cycle 6 of the General Social Survey, and applied to 1996 Alberta census estimates to calculate a denominator for the calculation of vaccine coverage for Alberta for 1996.


RESULTS
For the province of Alberta for 1996, it was estimated that about 281,000 persons aged 15 to 64 had a health condition that was an indication for influenza vaccination.


CONCLUSIONS
The application of age-sex-specific Canadian proportions to provincial census data will provide denominators for the estimation and comparison of vaccine coverage among high risk adults from year to year.
