Global and Regional Burden of Vaccine-Associated Erythema Multiforme and Their Related Vaccines, 1967-2023: An In-Depth Analysis of the World Health Organization Pharmacovigilance Database.

ABSTRACT:

Objective

Vaccine-associated erythema multiforme (EM) remains under-researched, impacting global vaccine safety evaluations. This study examines the global and regional burden of EM and its association with specific vaccines to optimize vaccination strategies.

Subject and methods

We analyzed data from the WHO pharmacovigilance database on vaccine-associated EM from 1967 to 2023 (n = 131,255,418 reports). Reporting frequencies, reported odds ratios (RORs), and information components (IC) were calculated for 16 vaccines across 170 countries.

Results

We identified 6,355 cases (males, n = 3,182 [50.07%]) of vaccine-associated EM from a total of 46,378 reports of all-cause EM. While vaccine-associated EM has been consistently reported, there has been a notable increase in
