A 29-year-old female asked:

Can getting the hepatitis a vaccine or immunoglobulin two weeks after exposure still prevent infection even if you're already testing positive for igm?

Hepatitis A: If you are developing igM antibodies two wks after exposure you are infected, and although immunoglobulin might provide added antibody protection, the vaccine would be superfluous. Not everybody who is infected with this virus actually develops symptoms and the overwhelming majority of patients recover uneventfully. Best wishes.
