Thank you for the references; unfortunately I don't live in the St. Louis area.
I found out that blood titers are not acceptable for the hepatitis vaccine, so
the search for a qualified doctor continues. I've found a lot of NDs and DCs,
but the college will only accept a letter from an MD, DO, PA, or NP.
I'm also doing research and compiling information, in the event that I have to
argue policy with the college.
