The 2014 Hib ACIP statement includes immunoglobulin deficiency in its “high-risk groups” for Hib disease, but the recommendations seem to imply that Hib vaccine is not necessarily for adults with immunoglobulin deficiency whose spleen is intact.

You are interpreting the recommendations correctly, and age is an important factor in this issue. The recommendation for Hib vaccination for asplenia applies to persons of all ages. The recommendation for Hib vaccination for immunoglobulin deficiency applies only to children 12 through 59 months of age.
