An event supposedly attributable to vaccination or immunization (ESAVI) is any unfavorable and unintended health situation (sign, symptom, abnormal laboratory finding, or disease) that occurs after vaccination or immunization and that does not necessarily have a causal relationship with the vaccination process or the vaccine. One of the essential components of a safe vaccination program is surveillance for ESAVIs. This special issue brings together the experience and expertise of several countries in the Region of the Americas, experts from national immunization programs, national regulatory authorities and other institutions in the surveillance of these events.
The Pan American Journal of Public Health thanks the Centers for Disease Control and Prevention of the United States for its programmatic and financial support for this special issue.
Additional manuscripts will be published in early 2025 as they become available.
