I don't know much about MU, but when I contacted ImmTrac, they said we can "attest" for the immunization registry if you have an ImmTrac user name and password. You just have to copy and paste some lines of exported vaccine information from your EMR into their attestation online form. I guess ImmTrac won't really accept that info as real but it's just a way for you to attest (?). I'm still waiting to hear back whether they can actually accept the HL7 info I exported from AC.
