I don't know that much about medicine, so this might be a funny
question, but do you really need to know that "shots 4 and 5 are
missing", or just that the patient needs to be shot two more times,
or do you really want the *application dates*?

This is a description of steps you decided would get you to your
goal. Instead of describing the steps, what's the goal?
