Summary of WHO and UNICEF Immunization Coverage Estimates for Malta (2021 Revision)

Overview

• Report Source: World Health Organization (WHO) and United Nations Children's Fund (UNICEF).
• Date: July 8, 2022.
• Purpose: Provides estimates of national immunization coverage for Malta based on data received as of July 7, 2022.
• Disclaimer: Estimates should be used with caution, graded based on empirical support.

Methodology

• Each country's data is reviewed individually without borrowing from other countries.
• Estimates rely on administrative data (typically numerator data and target population data) merged with survey and published literature.
• Grade of Confidence (GoC): Categorizes confidence in estimates ([R+], [D+], [S+]) and indicates potential challenges, ranging from "well-supported" to "estimate challenged by [R-, D-, S-]".
• Disclaimer: No probability model. Uncertainty is reflected only by the GoC rating.

Malta Immunization Coverage Findings (Visual Trends & Notes Provided)

Malta shows consistently high immunization coverage rates across multiple vaccines during the 2010-2021 period.

Key Vaccines and Notable Trends (Based on provided data plots/tables)

• BCG: NA for all years.
• DTP3: Fluctuations including years below 100% (98%, 97% in early 2010s) fluctuating upwards, consistently high coverage.
• Pol3: Similar to DTP3, high coverage (76%-99%).
• IPV1: Introduction of data in 2015 (est. 98% in 2021).
• MCV1/MCV2: High coverage rates (73%-88% for DTP-based MCV1 estimates).
• RV/Hib/PcV: High coverage for these component vaccines.
• HepB (birth dose & third dose): Incomplete data timeline (early years missing), rates fluctuate (low 70s mid-decade to high 90s late-decade).
• RotaC & D (DHIS): NA for earlier years, high late-decade coverage (90+%). No empirical data available for initial years.

Consistent High Coverage

• Overall, data indicates strong immunization performance in Malta, reflected in consistently high percentage estimates ranging typically from 97% upwards for vaccines tracked in recent years (BCG, DTP3, Pol3, etc.).

Data Confidence (GoC)

• The Grade of Confidence varied, often categorized as "Medium" (••) or sometimes "High" (•••) based on reported national government data support (R+) interpolated using the UN World Population Prospects (D+). Challenges (D-, R-, S-) were noted occasionally, usually referencing data incompleteness or lack of supporting surveys.
• Official, Administrative, and Survey sources were typically consistent with Estimated GoC ratings.

Important Considerations

• Disclaimer Reiteration: The analysis should be used with caution. While high GoC evidences data quality, misinterpretation or flawed use is possible.
