Insights
Pneumococcal conjugate vaccines (PCVs) in Colombia
Area of Science:
- Public Health
- Vaccinology
- Health Economics
Background:
- Pneumococcal diseases pose a significant public health challenge.
- Invasive pneumococcal disease (IPD), pneumonia, and acute otitis media (AOM) contribute to this burden.
- The National Immunization Program (NIP) in Colombia seeks cost-effective vaccination strategies.
Purpose of the Study:
- To conduct a budget impact analysis of pneumococcal conjugate vaccines (PCVs) within Colombia's NIP.
- To compare the costs associated with PHiD-CV and PCV-13 over a 5-year period.
- To inform vaccine selection under budgetary constraints.
Main Methods:
- A 5-year budget impact analysis (2020-2024) from a healthcare system perspective.
- Comparison of direct medical costs with and without PCV vaccination.
- Utilized published efficacy data and Pan-American Health Organization vaccine prices.
- Assumed 90% vaccine coverage based on Colombian data.
Main Results:
- PHiD-CV vaccination in Colombia's NIP could reduce pneumococcal disease treatment costs by US$46.1 million (2020-2024).
- PCV-13 vaccination could reduce costs by US$40.2 million over the same period.
- PHiD-CV has a lower budget impact (US$100.1 million) and annual vaccine dose cost compared to PCV-13 (US$121.4 million).
Conclusions:
- PHiD-CV offers a potentially more cost-effective option for Colombia's NIP.
- The findings support informed vaccine selection for national immunization programs facing budget limitations.
- Budgetary constraints can be managed effectively through strategic PCV implementation.
Abstract:
Objective: Pneumococcal diseases including invasive pneumococcal disease (IPD), pneumonia, and acute otitis media (AOM) impose a substantial public health burden. This study performed a budget impact analysis of the use of pneumococcal conjugate vaccines (PCVs) in the National Immunization Program (NIP) in Colombia.Methods: We compared the direct medical cost of the scenario without and with PCV vaccination using either pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) or 13-valent pneumococcal conjugate vaccine (PCV-13) over 5 years (2020-2024) from the health-care system perspective. Vaccine efficacy estimates were obtained from published sources and vaccine prices were taken from the Pan-American Health Organization Revolving Fund. Vaccine coverage was assumed to be 90% based on Colombia data.Results: Using PHiD-CV in the NIP in Colombia would reduce the estimated cost for treating pneumococcal disease by US$46.1 m over the 2020-2024 period (US$40.2 m using PCV-13), with a budget impact of US$100.1 m for PHiD-CV (US$121.4 m for PCV-13), and would cost US$3.1 m less per year on vaccine doses than using PCV-13.Conclusion: These findings are potentially valuable for the selection of vaccines for their national immunization programs under conditions of budgetary constraint.
