Note: These rules depend upon the availability of the CPP "immu" data uploaded from the EMR, which is only supported by some EMRs (e.g. PS Suite using Ocean Custom Form 3.52 or later).
The following rules can be copied and pasted into a Tablet Rule to prompt automatically.
Prompting for a Flu Shot / Influenza Vaccine Each Season (from Oct 15 until Mar 31)
