Too Difficult to Understand?

Had a hard time preparing for the pharmacy technician lecture. Course co-ordinator said to keep things simple as most of them have not gone through tertiary education. My in-charge wants a copy of my lecture as well, and I was wondering how to keep things simple enough for the technicians, and at the same time it still remains useful for the pharmacists. At times I think I lapse into the mode of preparing the slides for pharmacists and ended up using quite a fair bit of medical jargon.

Finished preparing the portion on national immunisation schedule today and was thinking it is too simple as I did not go into the disease states the compulsory vaccines cover and merely stated information that can be found in our institution's vaccine chart. Got to continue preparing the lecture. Another 5 more vaccines to go... (>_<)
