Mark that a Patient does not have Documented Immunizations
- Select the Immunizations tab. For example, you are determining if a new patient has a record of documented immunizations.
   If the patient has no documented immunizations, the No Known Immunization History check box appears on the Chart view toolbar.
 - Confirm no previous immunizations were administered.
 - If no immunizations were administered, select the No Known Immunization History check box. 
   
 - Close the Orders module.
   For reporting purposes, when the CCDA is generated, it displays that the patient has no known immunizations.
