Romania Immunization Coverage Summary (WHO/UNICEF, 2023)

Background

• Estimates based on reported data, surveys (occasional), administrative records, and expert opinion. Quality varies significantly. Grade of Confidence (GoC) reflects data quality. Oversight of disease epidemiology. Estimates potentially compromised by stockouts.

Vaccine Specific Immunization Coverage (2011-2022)

• BCG & DTP1/DTP3/Pol3/HepBB:

  • Coverage generally 80-99%, fluctuating. Below 90% intermittently related to global trends or schedules, sometimes due to administrative data challenges.
  • D- confidence grade indicates potential bias and unreliable data.

• MCV1/MCV2:

  • MCV1: Consistently >80% (e.g., 89-93%), tied to disease epidemiology.
  • MCV2: Confidence decreases; coverage more variable, often linked to methodological issues identified in the data.

• RCV1:

  • Estimates rely on MCV1 data (as RCV data quality/availability is low or not tracked).

• HepB/HepB3:

  • Birth dose (HepBB) consistently high (~94-99%).
  • HepB3: Coverages fluctuate (~86-96%). Confidence often R+ or D-, potentially indicating stock issues or data gaps.

• Hib3:

  • Coverage typically around 85-92%. Low confidence (R+, D-, D-R-) often due to unknown data quality, reliance on reported data, or stockouts.

• IPV1:

  • Tracking began in 2015. Coverage existed pre-2015 via MCV/IPV estimates.
  • High confidence (>90%) before 2016, then affected by stockouts and unreliable methods (GoC N/A). Recent years low confidence.

• RotaC/PcV3:

  • RotaC: No estimates pre-2019 - onset via MCV challenges. Recent coverage slightly below 90%.
  • PcV3: Pneumococcal conjugate vaccine introduced Oct 2017. Tracking began 2019. Coverage >85% from ~2019 onwards, but only a few years of data.

General Notes

• Declined confidence grades (D-, D-R-, R+) frequently reflect concerns about inaccurate numerator/denominator data or inadequate empirical support.
• Interpolation occurred between data points for some years if no new data or surveys were available.
• No national representative surveys in 5 years prior to this report (as of 2023) for key indicators like DTP1, DTP3, Pol3, etc.
• Strong recommendations for high-quality surveys to validate reported data.
