Purpose
Contraindications/Precautions Date
Description: The date/time the patient contraindication or precaution was observed. See "Contraindications/Precautions" under Allergies and Intolerances for vaccination contraindications/ precautions.
Rationale for inclusion:
- Enhances immunization forecasting accuracy by incorporating dates related to contraindications and precautions into patient records, allowing the IIS to generate personalized vaccination schedules for pediatric, adolescent, and adult populations in accordance with recommended guidelines.
- Facilitates effective investigation and reporting of vaccine adverse events by providing essential date information regarding when contraindications or precautions were identified, helping public health officials assess potential risks associated with vaccinations and improve safety monitoring efforts.
- Strengthens reminder and recall activities by utilizing contraindication and precaution dates to identify patients who may require alternative vaccination strategies or follow-up consultations based on their medical history, ensuring that outreach efforts are both safe and effective.
- Enables IIS users to query and identify patients with specific contraindications or precautions, allowing targeted searches for individuals who should not receive certain vaccines or require special considerations.

Date of Immunity Evidence
Description: The date/time of patient immunity due to serological or clinical evidence was observed.
Rationale for inclusion:
- Enhances immunization forecasting accuracy by incorporating the dates of vaccine-preventable diseases, which allows the IIS to assess individual patient risk and tailor vaccination schedules.
- Supports comprehensive reporting needs by providing critical data on the occurrence of vaccine-preventable diseases, enabling federal and jurisdictional immunization programs to monitor trends, outbreaks, and vaccination effectiveness effectively.
- Facilitates partner and provider onboarding by equipping healthcare professionals with essential information regarding past occurrences of vaccine-preventable diseases during vaccine management efforts, particularly in public health emergencies or outbreak responses.

Evidence of Immunity
Description: The disease the patient is expected to be immune to on the basis of serological or clinical evidence.
Rationale for inclusion:
- Improves immunization forecasting precision by integrating titer results related to vaccine-preventable diseases, enabling the IIS to evaluate immunity levels and customize vaccination schedules.
- Enhances reporting capabilities by supplying vital data on titer levels for vaccine-preventable diseases, allowing federal and jurisdictional immunization programs to track population immunity and identify areas that may require focused interventions.
- Aids partner and provider onboarding by providing healthcare professionals with crucial information about patients' titer histories during vaccine management efforts, especially in response to outbreaks of vaccine-preventable diseases or public health emergencies.
