Immunization coverage estimates for Solomon Islands, produced by WHO and UNICEF, are based on national data, surveys, administrative records, or interpolation, with confidence levels indicating data reliability. Reports note systemic issues such as incomplete reporting, lack of authoritative surveys, and funding disruptions affecting coverage quality. Estimates are detailed for 17 vaccine antigens, spanning various years from 2005 to 2021, with a 2021 revision.

Key antibiotics covered include:

• Diphtheria-Tetanus-Pertussis (DTP), including DTP1 and DTP3 doses.
• Polio vaccines (Pol3 and birth doses of Inactivated Polio Vaccine (IPV1)).
• Measles Containing Vaccines (MCV1 and MCV2).
• Rubella Containing Vaccines (RCV1).
• Hepatitis B doses (HepBB and HepB3).
• Haemophilus Influenzae Type b (Hib3).
• Rotavirus (RotaC) and Pneumococcal Conjugate Vaccine (PcV3).

Common trends in coverage include fluctuations due to data quality, birth cohort sizes, and vaccination schedule changes. For instance, MCV1 saw declines in 2012-2013, attributed to reduced activity. Introduction of vaccines like RotaC (2020) boosted coverage, but older vaccines like BCG often face incomplete reporting. DTP3 estimates declined slightly in 2013 due to funding suspensions. Pol3 coverage has persisted with variations, influenced by provincial funding cuts. Confidence levels vary: C sources show higher reliance on national data with surveys, leading to recommended national surveys to improve accuracy.

The estimates reflect national assessments or interpolated data, carrying inherent risks due to potential biases. Methodologies involve calibrating data from World Population Prospects and employing a Grade of Confidence (GoC) system, with comprehensive data sources preferred but often lacking, particularly surveys post-2005. Use with caution guided by the objective priority.
