Vaccine name, eligibility, doses, and cost

Product: ERVEBO, a one-dose live vaccine against Zaire ebolavirus for people age 12 months and older. In the United States it is used for specified occupational, outbreak-response, or exposure risks rather than routine public vaccination.

Approximate U.S. cost: ERVEBO is not a routine retail vaccine in the United States. It is generally supplied through occupational or public-health programs, so a standard consumer self-pay price is not meaningful.
