Key Evidence: A study of insurance claims in the U.S. for children under five estimated that, from 2007 to 2011, rotavirus vaccination prevented more than 176,000 hospitalizations, 242,000 emergency room visits and more than 1.1 million outpatient visits due to diarrhea — saving an estimated $924 million in direct health care costs over four years.
Key Evidence: Vaccinating children against rotavirus in Bangladesh would prevent more than 50,000 outpatient visits and 40,000 hospitalizations in children under five each year, and reduce treatment costs by US$5.8 million over 2 years — nearly all (96%) from fewer hospitalizations. Since this study didn’t take herd effects into account, the actual impact would likely be greater.
Key Evidence: If China — one of the few remaining countries in the world that haven’t introduced Hib vaccine in their national immunization program — decides to include the vaccine in their program, it could actually be cost saving; the vaccination costs would be less than the averted costs of illness from Hib meningitis and pneumonia, if a vaccine price matching UNICEF’s (US$2/dose) can be obtained. The vaccination will be cost-effective, but not cost saving, if the program pays the current market price in China of US$10 per dose.
Key Evidence: In a study using actual data on hospitalizations and costs before and after PCV-10 vaccine was introduced in Brazil, an estimated 463,000 hospitalizations from all causes of pneumonia were prevented in persons less than 65 years of age over 5 years following introduction of the vaccine — saving an estimated US$147 million in hospitalization costs. Half of the costs averted were due to fewer hospitalizations in children under five, who were targeted for the vaccine, while the remaining half were due to fewer hospitalizations in persons 5-49 years of age, as a result of herd protection.
Key Evidence: Vaccination of infants with pneumococcal conjugate vaccines in 180, from the health system perspective, would save an estimated $3.2 billion per year worldwide in treatment costs and an additional $2.6 billion in societal costs (from reduced missed work and out-of-pocket expenditures)- for a total of $5.8 billion. These savings would partially offset the estimated global cost of vaccination of $15.5 billion per year.
From the VoICE Editors: The cost estimates were calculated in international dollars.
Key Evidence: In 41 Gavi-eligible countries, it is estimated that without any rotavirus vaccine (RVV) coverage, an estimated 2.2 million Catastrophic Health Costs (CHC) cases and 600,000 Medical Impoverishment (MI) cases would occur due to rotavirus gastroenteritis. Unfortunately these figures would not significantly decrease under the current immunization forecasts because very few countries have introduced the RVV. However, with the introduction of RVV the number of CHC cases would drop to 1.3 million and MI cases to 400,000, representing a 40% reduction.
Key Evidence: Researchers estimate that vaccinating against 10 diseases in the world’s 94 poorest countries between 2011-2020 will avert US$586 billion in costs of illness (including treatment costs, transportation costs, lost caretaker wages and productivity losses due to death and disability). The 73 Gavi-supported countries account for US$544 billion of the treatment costs averted.
