Introducing seasonal influenza vaccine in low-income countries: an adverse events following immunization survey in the Lao People’s Democratic Republic

Influenza and Other Respiratory Viruses, January 2015

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).

Following the 2012 PIVI donation to Laos, members of the PIVI team from CDC and the Laos Ministry of Health conducted a survey among 2,089 persons who received the influenza vaccine. The survey focused on identifying adverse events following immunization and gathering information regarding participants’ attitudes towards the vaccine. This paper describes the survey’s findings and provides insight into how the CDC team works with country partners to build capacity around influenza vaccination.
