Objective In 2012, Lao PDR introduced seasonal influenza vaccine in pregnant women, persons aged ≥50 years, persons with chronic diseases, and healthcare personnel. We assessed adverse events following immunization ( AEFI ). Methods We used a multistage randomized cluster sample design to interview vaccine recipients. Findings Between April and May 2012, 355 902 were vaccinated. Of 2089 persons interviewed, 261 (12·5%) reported one or more AEFI . The most commonly reported AEFI s were local reactions. No hospitalizations or deaths were reported; 16% sought medical care. Acceptance and awareness of vaccination were high. Conclusions Following the introduction of seasonal influenza vaccine in Lao PDR , self‐reported adverse events were mild.
