Bahamas Immunization Coverage Summary

According to the WHO and UNICEF estimates for the 2021 revision (data received as of July 7, 2022), the following national immunization coverages for key vaccines in the Bahamas are summarized:

• BCG: No national-level estimates available for the years 2010–2021 due to limitations in data sources.

• DTP1/DTP3:

  • Coverage levels declined from the early 2010s to 2021, with the DTP3 estimated at 79% in 2021 but showing challenges in data reliability.

• Pol3/Polio:

  • Coverage remained steady at around 94–98% for most years; however, reporting declined in 2021 requiring verification by WHO/UNICEF.

• IPV:

  • First recorded in 2015 at 31%. Coverage improved to over 95% by 2017 but sharply dropped to 79% in 2021.

• MCV1/MCV2:

  • MCV1 had declining reports since 2017; MCV2 coverage was around 80% from 2010–2019. Changes in recommended age doses also impacted data consistency.

• HepB birth dose:

  • Not assessed due to country-specific policies.

• Rotavirus (RotaC):

  • Estimated at 75% in 2021 but faced survey challenges.

• PCV3/Hib:

  • Introduction in 2012/2013 led improvements initially, though recent years (2019–2021) saw declines.

Notes

• General Context:
  • Country-specific best estimates were used without data borrowing from other nations.
  • National surveys were lacking, requiring cautious reliance on reported administrative data, often recalculated using official denominators and UN population data.
  • Grade of Confidence (GoC): Red flags for data challenges were marked (e.g., D- for denomiator issues).

This overview highlights steady or declining immunization coverage trends across several key vaccine antigens in the Bahamas during the past decade. For complete details on methodologies or prior years, refer to the available datasets via UNICEF and WHO.
