After I gave Adacel vaccine to a patient, I went to:
Health maintenance in the encounter screen, then to
HM: Immnuzations and Shots.
Selected Adacel from the list of vaccines and put in all the informations about Adacel and then click save.

I went back to the HM: Immunizations & Shots screen of the same patient and in the "Prior records of 'TdaP" box are these:

07/26/2010 7:23:12 pm Td (tetanus,diphtheria)
07/26/2010 7:23:12 pm TdaP

I gave Adacel (TdaP) but NOT Td.

Deleting either Td or TdaP in
Summary Sheet
'Complete' under Health maintenance and Injections
will delete both Td and TdaP.

Printing the shot records from this screen will show that both Td and Tdap were given. Scary if this record goes to other parties.

I don't know if this happens to anybody else. Any solution to this? And how do you get rid of that time of administration?
Other vaccines seem ok.

Thanks for your help.
