The report details WHO and UNICEF's estimates of national immunization coverage for Albania based on data up to July 2021. These estimates cover various vaccines, including BCG, DTP1, DTP3, Pol3, IPV1, MCV1, MCV2, RCV1, HepBB, HepB3, Hib3, RotaC, and PcV3, from 2010 to 2021.

Estimates are primarily based on administrative data reported by national authorities, supported by survey data and population denominators. The Grade of Confidence (GoC) indicates the empirical support for each estimate, with GoC=R+ D+ for well-supported data, GoC=No accepted empirical data for challenges, and varying GoC levels overall.

Key findings show high coverage (often 98-99%) for most vaccines in recent years, but some years exhibit declines or uncertainties due to unexplained decreases or data challenges. For instance:

• BCG, DTP1, DTP3, and MCV1/DTP3 consistently show coverage around 99% post-2010, but earlier years include notations of data issues.
• IPV1 and Pol3 estimates are intermittent, with some years lacking high-confidence data.
• HepBB and HepB3 coverage is generally robust, but D- notations indicate potential denominator issues.
• RotaC and PcV3 show intensification from 2020, with some confidence challenges.

Surveys, such as the 2016-2018 Albania DHS, provide supportive evidence for many vaccines, reinforcing reported coverage but highlighting variations.

All estimates are to be used with caution due to variability in data quality and no standard uncertainty measures provided. For detailed data, refer to WHO/UNICEF sources.
