Below is a link to a PDF with the annual rates for two-year olds.
Oregon immunization rates measure vaccination levels among two-year-olds in a given year. Rates are based on ALERT Immunization Information System (IIS) data for all two-year-olds with an Oregon address and a post-birth immunization record. In the past, rates were adjusted based on estimates of missing data but we have discontinued that process because the system is so well populated. Over 95% of all childhood immunizations given in Oregon since 1999 are in ALERT and reporting levels are even higher in recent years.
If you have any questions regarding how these rates were calculated please call the Douglas Public Health Network at 541-440-3571.
