Vaccines are an incredible investment, and save up to 44 dollars to the dollar

Vaccines can save up to 44 dollars to the dollar, says a new study, published in Health Affairs. Projected vaccination rates of 94 low- and middle-income countries from 2011 to 2020 were used to determine the economic benefits. Two separate approaches were used in the study:
The first looked at the “cost-of-illness” and focused on things like the cost of treatment and productivity losses. This approach found a 16 US dollar return on every one dollar spent. The second was the “full-income approach” which looked at the broader economic and social benefits of living a longer and healthier life. This approach found a 44-dollar return on every one dollar spent. Supply chain, service delivery and vaccine costs were all included to determine the prices of vaccinations.
The study assessed 10 vaccine-preventable infections: Haemophilus influenzae type b, hepatitis B, human papillomavirus, Japanese encephalitis, measles, Neisseria meningitis serogroup A, rotavirus, rubella, Streptococcus pneumoniae and yellow fever.
