Summary of WHO and UNICEF Immunization Coverage Estimates for Norway, 2021 Revision

Source: WHO and UNICEF, July 8, 2022

Background

WHO and UNICEF estimate national immunization coverage based on data from member states, surveys, empirical research, and population registers. These estimates distinguish reliable from potentially biased data, avoiding adjustments for local biases and relying on empirical support.

Key Findings for Norway

• Immunization coverage for key vaccines (e.g., BCG, DTP1, DTP3, Pol3, MCV1, MCV2) has remained consistently high or stable from 2010 to 2021.
• Most vaccines achieved coverage above 90%, with values ranging from 91% to 99%. Notable examples:
  • BCG: 99-100%
  • DTP1: 98-99%
  • DTP3: 93-97%
  • Pol3: 93-97%
  • MCV1: 93-97%
  • HPV: 91-95% (relevant data included).
• Coverage declined minimally in some years but overall remained high, indicating robust immunization system performance.

Methodology

• Estimates primarily use national reports, administrative data, population registers, and survey-based assessments where available.
• Grade of Confidence (GoC) indicates empirical support:
  • "•••": Strong support from reported data, correct denominators, and recent surveys.
  • "••": Support from at least one data source without challenges.
  • ".": Limited or conflicting data.
• No subjective uncertainty ranges provided due to lack of probabilistic models.

Confidence and Disclaimers

• Estimates may be unreliable due to data biases, with minimal verification relied upon.
• Data sources vary, and without independent assessments, coverage levels should be evaluated cautiously.
• Reports emphasize potential risks in data accuracy and recommend high-quality empirical reviews for confirmation.
