Regarding the Hep B status on the portal, y0u can ignore that. It's an outdated status. They only use CastleBranch to track immunizations.
Source: E-mail sent last year from Nora Few (Executive Assistant Dean, UIUC). Even though she only coordinated incoming Urbana M1s, it was the same for Chicago too. Here's a direct quote. (I think "Certified Profile" was renamed to "MyCB" at some point.)
"do not worry about the UIC status page with respect to your immunization completion; if you have been cleared by Certified Profile you are compliant"
