Belgium Immunization Coverage Summary (WHO & UNICEF, 2021 Revision, July 8, 2022)

BCG Vaccine: No estimates available for 2010-2021.
DTP1 (Diphtheria/Tetanus/Pertussis): Coverage consistently high (98-99%), stable or slight decreases noted in some years (e.g., 99% in 2020-2021), supported by surveys and government data with GoC R+.
DTP3 (Third Dose): Coverage around 97-98%, minor fluctuations (e.g., 99% in 2016-2019, 97% in 2021), based on surveys and stable coverage assumptions, GoC R+.
Pol3 (Third Dose of Polio): Coverage high and stable (e.g., >98%), reflecting routine immunization performance, GoC R+.
IPV1 (Inactivated Polio): Coverage estimates available from 2015 onward (~99%), introduced to mitigate polio risks, GoC R+.
MCV1 (Measles First Dose): Coverage around 95-96%, stable or slight variations, based on surveys and government data, GoC R+.
MCV2 (Measles Second Dose): Coverage extrapolated or based on assumptions in some years (e.g., 83-85% range), with GoC No accepted empirical data in 2021.
RCV1 (Rubella First Dose): Coverage estimated based on MCV1, around 95-96%, GoC R+.
HepB3 (Hepatitis B Third Dose): Coverage stable around 97%, based on surveys and government data, GoC R+.
Hib3 (Haemophilus influenzae Type b Third Dose): Coverage around 96-98%, stable with slight variations, GoC R+.
RotaC (Rotavirus): Coverage varies (e.g., ~80-90%), lower than other vaccines, based on surveys, GoC R+.
PcV3 (Pneumococcal Conjugate Third Dose): Coverage around 90-95%, stable with minor fluctuations, GoC R+.
Methodology: Estimates rely on empirical data (e.g., surveys, administrative reports), with no adjustments from other countries. A grade of confidence (GoC) indicates data support level, but no confidence intervals provided. Estimates should be used cautiously due to potential data biases or gaps.
Survey Details: Data from Flanders, Wallonia, and Brussels regions based on regional surveys (e.g., 2010-2021), with population-weighted samples and card checks confirming coverage.
Trends: Immunization coverage has been high and relatively stable for most vaccines, with minor decreases in some doses but no significant dips in overall key indicators. Rotavirus coverage remains lower.
