Annual WHO/UNICEF Estimates of National Immunization Coverage (WUENIC) for ~195 countries, 1980-2025 (keyless UNICEF Data Warehouse SDMX, Immunisation dataflow): eight headline antigens (DTP1/DTP3, MCV1, BCG, HepB birth dose + 3rd dose, Hib3, RCV1) with a derived ML layer — the zero-dose-children proxy, DTP1->DTP3 dropout, DTP3 year-over-year change, per-year DTP3 ranks and the sub-90% IA2030 target flag. The vaccination-coverage layer for public-health, development and country-risk models; joins on (country_code, year) with the catalog's other global panels. Annual modeled estimates, not survey points.

Column	Type	Description
year	integer	Estimate reference year (TIME_PERIOD); annual WUENIC modeled estimates, 1980-2025.
country	string	Country name from the catalog's canonical ISO3 mapper.
country_code	string	ISO 3166-1 alpha-3 country code (UNICEF Data Warehouse field REF_AREA; regional aggregates dropped).
dtp1_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_DTP1: Diphtheria, tetanus and pertussis, 1st dose (% of children 12-23 months). (unit: percent)
dtp3_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_DTP3: Diphtheria, tetanus and pertussis, 3rd dose (% of children 12-23 months). (unit: percent)
mcv1_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_MCV1: Measles-containing vaccine, 1st dose (% of children 12-23 months). (unit: percent)
bcg_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_BCG: BCG tuberculosis vaccine at birth (% of live births). (unit: percent)
hepb3_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_HEPB3: Hepatitis B, 3rd dose (% of children 12-23 months). (unit: percent)
hib3_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_HIB3: Haemophilus influenzae type b, 3rd dose (% of children 12-23 months). (unit: percent)
rcv1_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_RCV1: Rubella-containing vaccine, 1st dose (% of children 12-23 months). (unit: percent)
hepbb_pct	float	WUENIC estimate, UNICEF SDMX indicator IM_HEPBB: Hepatitis B birth dose (% of live births). (unit: percent)
zero_dose_proxy_pct	float	100 minus DTP1 coverage: the standard zero-dose-children proxy — share of children receiving no DTP dose. (unit: percent)
dtp_dropout_pct	float	(DTP1-DTP3)/DTP1*100: health-system follow-through signal between the first and third DTP dose; null when DTP1 is missing or zero. (unit: percent)
dtp3_yoy_change_pp	float	Within-country year-over-year change of DTP3 coverage in percentage points; null for a country's first observed year. (unit: percentage points)
dtp3_rank	integer	Per-year cross-country rank on DTP3 coverage (1 = highest coverage).
dtp3_below_90_flag	integer	1 when DTP3 coverage is below 90% (the IA2030/WHO coverage target), else 0.
row_hash	string	Deterministic 12-hex row identity hash over source, country, year and rounded raw antigen values.
