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. For more information, please see our Q&A here.
Oregon two-year-old immunization rates are now available for 2017. Rates have continued to increase year after year, going from 60% in 2014 to 68% in 2017 for the full 4:3:1:3:3:1:4 vaccine series. All individual antigen rates have either increased slightly or stayed level, with DTaP rates hitting 80% for the first time ever and others approaching the Healthy People 2020 goal of 90% coverage. These improvements reflect the hard work of our local health departments and clinical partners.
Vaccination rates have increased particularly among those not on public assistance programs like WIC, DMAP, or VFC, possibly reflecting the strides toward universal health insurance coverage and no-cost preventative care, though rates of those on public assistance continue to tick upward as well.
