Note that this error is in ImmunizationEvaluation, but that's not a resource option in gForge right now.

Section 11.14.5 of ImmunizationEvaluation has several typos

Typically a single "recommendation" is prepare_ + d + _ for the patient based on the evaluation of all of the vaccine administration events in the patient's history. This "recommendation" may include individual recommendations for multiple vaccines/vaccine groups. For example, a recommendation may be generate_ + d + _ that includes recommendations for both - + _ an _ + - influenza and a diphtheria/tetanus vaccination+ _ s _ +. Such recommendations use the ImmunizationRecommedation resource.
