Abstract

OBJECTIVES:

To describe the initial coverage and impact of a pneumococcal and influenza vaccination program for at-risk Indigenous adults in Far North Queensland that formally commenced in 1996.

DESIGN:

Ascertainment of vaccine coverages, and prospective laboratory surveillance of invasive pneumococcal disease occurring in Indigenous adults in the region.

MAIN OUTCOME MEASURES:

Coverages of the first doses of both vaccines administered since 1995, and the incidence of invasive pneumococcal disease in Indigenous adults in the region between 1993-2000.

RESULTS:

Most (96% and 73%) of the Indigenous adults > or = 50 years of age received influenza and pneumococcal vaccines, respectively, for the first time between 1995-2000. Assuming that either 33% or 50% of Indigenous adults 15-49 years of age in Far North Queensland were eligible for vaccination, then either 109% or 72% of this population received influenza vaccine, and either 75% or 50% received pneumococcal vaccine, respectively, for the first time between 1995-2000. The incidence of vaccine-preventable invasive pneumococcal disease fell from 111 (95% confidence interval [CI] 77-154) cases per 100,000 per year in 1993/94 to 28 (95% CI 13-53) cases per 100,000 per year in 1999-2000 (p<0.05).

CONCLUSION:

Although there was a significant decline in the incidence of invasive pneumococcal disease, the vaccine coverages after five years of the program were suboptimal. Because of the difficulties in targeting the 15-49 years age group and because of unrecognised risk factors, we suggest that a universal Indigenous adult pneumococcal and influenza vaccination program should be considered.
