Vaccines: quantities, production and costs
Insights
Annual global immunization requires hundreds of millions of vaccine doses. A simplified vaccination schedule can reduce costs and improve vaccine administration efficiency for diseases like DTP-polio, measles, and BCG.
Area of Science:
- Public Health
- Vaccinology
- Global Health Initiatives
Background:
- The Expanded Programme on Immunization (EPI) of the World Health Organization targets major childhood diseases.
- Annual global birth rates necessitate substantial vaccine quantities for diseases like DTP-polio, measles, and BCG.
Purpose of the Study:
- To assess the feasibility of producing and administering required vaccine doses globally.
- To explore strategies for reducing immunization program costs and improving vaccine delivery.
Main Methods:
- Analysis of global birth rates and projected vaccine needs.
- Evaluation of modern fermentation technologies for vaccine production.
- Review of clinical studies on simplified vaccination schedules.
Main Results:
- Modern fermentation technologies make large-scale vaccine production economically feasible.
- A simplified vaccination schedule has demonstrated effectiveness in clinical settings.
- Reducing administration costs is key to lowering overall immunization program expenses.
Conclusions:
- Global vaccine production is achievable with current technologies.
- Simplified vaccination schedules offer a viable solution for efficient vaccine administration.
- Optimizing vaccine delivery strategies can significantly decrease immunization program costs.
Abstract:
At a birth rate of about 150 million children per year, 300 to 400 million doses DTP-polio and 150 to 200 million doses of measles and BCG vaccines will be required annually for immunization of the world population against the target diseases as defined by the EPI of the World Health Organization. With the introduction of modern fermentation technologies production of these quantities is practically and economically feasible. The main problem is the administration of the vaccine to the target population. This may be achieved by application of a more condense and simplified vaccination schedule which has shown to be effective in clinical studies. Also, the costs of the immunization programmes may be considerably reduced in this way as the costs of administration form the major part of any immunization programme.
