The vaccine safety advice network is a collaborative pilot project between Vanderbilt University Medical Center, the Tennessee Department of Health, and the Centers for Disease Control and Prevention to assess the feasibility of addressing vaccine safety questions posed by healthcare providers in near real-time. Using a two-tier response system and an electronic database for query submission, the pilot project received ten queries in three and one half months. Two of three pre-specified benchmarks for program evaluation, addressing queries within 24 h of receipt and 100% provider satisfaction, were met; one benchmark, the percentage of questions addressed by Tier 1 staff, was not met. Limitations included few submitted queries primarily involving children in the pilot period, "after-only" program evaluation, and limited geographic generalizability. The study demonstrates a successful partnership between federal, state and academic institutions and a feasible method to respond to healthcare provider inquiries about vaccine safety in near real-time.
