Review on pertussis case definitions: a need for reliable disease surveillance.

BMC infectious diseases·2026

Fever is a common side effect of vaccines, particularly in children. Standardizing fever definitions is crucial for accurately comparing vaccine safety across studies.

Area of Science:

  • Pediatric medicine
  • Immunology
  • Public health

Background:

  • Fever is a common systemic adverse event following immunization, especially in infants and young children.
  • Distinguishing vaccine-related fever from fever due to underlying infections is critical for vaccine safety monitoring.
  • Inconsistent fever definitions and assessment methods hinder comparability of fever rates across studies and vaccines.

Purpose of the Study:

  • To highlight the importance of standardized fever definitions in post-vaccination adverse event surveillance.
  • To advocate for the adoption of standardized case definitions for fever following immunization.
  • To improve the accuracy and comparability of fever data in vaccine safety assessments.

Main Methods:

  • Review of existing literature and analyses on post-immunization fever.

  • Analysis of challenges in comparing fever rates due to varying definitions.
  • Introduction of a standardized case definition for fever by the Brighton Collaboration.

    • Main Results:

    • Fever following immunization can be vaccine-related or coincidental with underlying diseases.
    • The temporal pattern of vaccine-attributable fever varies depending on the vaccine type.
    • Lack of standardized fever definitions impedes reliable comparisons of vaccine safety data.

    Conclusions:

    • A standardized case definition for fever is essential for accurate and comparable assessment of post-immunization adverse events.
    • Adoption of the Brighton Collaboration's standardized fever definition is strongly recommended.
    • Standardization will enhance the reliability of vaccine safety surveillance and comparative effectiveness research.
