The WHO and UNICEF 2022 revision of immunization coverage estimates for Guyana provides detailed assessments of vaccine coverage for key immunizations such as Bacillus Calmette-Guerin (BCG), Diphtheria-Tetanus-Pertussis (DTP), Polio, Measles, Rubella, Hepatitis B, Haemophilus influenzae type b (Hib), Rotavirus, Pneumococcal conjugate, and Yellow Fever vaccines, covering the period from 2011 to 2022. Estimates are based on a combination of national reports, surveys, and empirical data, with a Grade of Confidence (GoC) assigned for data reliability, which can range from challenged to well-supported. Most vaccines show high coverage rates (typically above 90%) in recent years, but fluctuations occur due to factors like reported vaccine stockouts at national or subnational levels and inconsistencies in survey data. The GoC indicates that estimates should be used with caution owing to potential biases or data limitations, and the next revision is scheduled for July 15, 2024, based on data received by June 26, 2023. Overall, the data highlights progress but underscores vulnerabilities in the immunization system.
