Access to DTP-Based Combination Vaccines in Asia-Pacific Countries between 2019 and 2022.

Access to DTP-Based Combination Vaccines in Asia-Pacific Countries between 2019 and 2022.

Publication date: Dec 28, 2023

The Asia-Pacific countries are highly diverse in health and economic conditions that may impact vaccine access and uptake. Our study aimed to characterize patterns of health access to DTP-based combination vaccines in 10 countries from 2019 to 2022 using the IQVIA-MIDAS database. The availability, affordability, and accessibility were compared across countries by national health and economic performance indicators using Spearman’s rank correlation coefficient. Our findings showed that the three aspects of access to DTP-based vaccines varied substantially in the Asia-Pacific region, with higher levels in countries with better health and economic performance. Affected by the COVID-19 pandemic, vaccine accessibility fluctuates significantly in lower-income countries, with DTP coverage rates falling by more than 14% in the Philippines and Indonesia between 2019 and 2021. For availability and affordability, Singapore and Malaysia from high-income groups were largely affected, which may be related to health expenditure as a percentage of gross domestic product (Coefficient = 0. 39, p = 0. 03). Our study indicates that greater attention needs to be paid to national health expenditure and routine immunization services to improve vaccine disparities and increase the robustness and resilience of the vaccine supply chain during public health emergencies.
