Oregon Population-Based Rates (PBR)
Why are PBRs important?
ALERT Immunization Information System (IIS) data provide a great starting point for assessing population-based rates in Oregon because the system is so well populated. Over 95% of all childhood immunizations given in Oregon since 1999 are in ALERT. Using this data, the Immunization Program developed a methodology to measure county rates for two-year-olds and adolescents that accounts for mobility in and out of the state and allows for comparisons among counties.

The National Immunization Survey (NIS)
The NIS is a phone survey of families of young children and their healthcare providers. Its purpose is to collect immunization data to determine coverage rates nationwide. The NIS is a useful tool for monitoring immunization trends over time for each state and to detect changes in coverage levels among states. The NIS surveys approximately 200-400 families, which allows for state-to-state comparisons and state trending over time, but it does not allow for any estimates of sub-populations in Oregon, such as county rates.
