You can confirm that these are degraded entries by going to the corresponding date in Care History (shown by the red square) tab:
Note the red [DEGRADE] alerts next to the data, which confirm that these are degraded codes transferred via GP to GP.
How to correct "degraded" entries
To correct these, edit the consultation where the entries were entered. Do this by finding the consultation in "Consultations" and selecting the blue bar at the top by clicking on it. Then right hand mouse click and select "Edit Consultation" :
Open the OneTemplate Non-Prescriber template and use this to replicate the data that already exists in a degraded form. Ensure that all attributes are replicated to maintain information integrity (eg: batch number, expiry date, site). Once you have done this the original (degraded) data can be deleted. This will have solved the degrade issues and the patient's vaccination history in Care History should be complete, as well as showing correctly in searches and protocols.
When replacing codes be sure to set the GMS flag to "No"
