Report on the United States Vaccine Industry

U.S. Market Summary

In summary, the U.S. market is dominated by four major suppliers, all which have grown

and 1980s, increases in doses from new vaccines and extensions to the schedule fueled growth
in the 1990s. These additions to the vaccine schedule have raised significantly the total
immunization cost per child but have also provided valuable health benefits to the public. To
better understand the underlying economics of the business, the study now turns to an analysis
of vaccine industry economics and the profitability of vaccine suppliers.
