The Oregon Immunization Program (OIP) is using the ALERT Immunization Information System (ALERT IIS) to report on seasonal influenza uptake across the state. As a synopsis, ALERT IIS receives both child and adult immunization reports from the majority of Oregon healthcare providers and payors. Based on last year’s influenza season, OIP estimates that ALERT IIS is capturing 75% to 80% of all influenza immunizations given in Oregon. For near-real time tracking out of ALERT IIS, the data on immunizations are lagged by two weeks. Estimates made with two weeks of lag for reporting are generally good.

Additional seasonal influenza surveillance updates
are available from the Oregon Public Health Division’s Flu Bites report.
Week 40: Through Oct. 4th, ALERT IIS already has over 200,000 reports of seasonal influenza immunizations for Oregon residents. OIP estimates that at least a quarter-million Oregonians have received an influenza immunization to date. Overall, the current influenza immunization season looks similar to last year’s season, but it is too early to forecast the whole season or when immunizations will peak. The majority of adult influenza immunizations (56%) so far were given in a medical setting such as a doctor’s office. However, pharmacists also account for a substantial amount (39%) of reported adult influenza immunizations. As of week 40, 61% of adult influenza immunizations have gone to women, as opposed to only 39% to men. This is the same as last season where adult women at all ages accounted for more reported immunizations than did men.
The final influenza vaccination uptake report for the 2013 - 2014 season is available. This report looks at uptake rates by demographic characteristics of the vacinees, geography and settings, and adult pharmacy usage.
