  • About PhilaVax


    In 1993, with funding from the Robert Wood Johnson Foundation, Keystone Mercy Health Plan, and the Centers for Disease Control & Prevention (CDC) the Kids Immunization Database/Tracking System (KIDS) was started. The mission of the project was to develop, implement and evaluate an immunization tracking system for Philadelphia’s residents. In 2007, the first web-based KIDS system was created allowing users direct access through a secure website. The most recent upgrade in 2012 to the KIDS Plus IIS used today, continued the secure web-based access and included additional immunization practice tools for providers.

    From its start, PhilaVax has included children from 0 – 7 years of age, expanding twice. In 2007 the Philadelphia Board of Health regulation was expanded to require reporting on patients 0-18 years old and an addition expansion in 2009 requires reporting on all adults over 18 years. Reporting on all immunizations administered through the lifespan is required by a Philadelphia Board of Health regulation.

    What can PhilaVax do for my practice?

    An immunization information system is an important tool to increase and sustain high immunization coverage rates by consolidating immunization records from multiple providers, allowing providers to generate recall notices for individuals who are not up-to-date, minimizing over-immunization, and identifying missed opportunities for immunization. The following tools are available in the PhilaVax for providers:

    • Quick patient immunization history search
    • Built-in recommendations to show which vaccines are due for the patient
    • Printable school immunization forms
    • Practice-specific patient remind and/or recall reports
    • Practice-specific immunization coverage rates
    • Practice-based patient roster

  • Reporting Requirements

    Reporting Immunizations is Required

    Pursuant to its public health authority under § 6-210 of the Philadelphia Health Code, the Philadelphia Board of Health has issued regulations that mandate reporting of immunization data on all immunizations administered to all individuals in the city of Philadelphia — children 0-18 years of age and adults over 18 years of age — to a citywide immunization information system.

    PhilaVax requires providers to report at least once a month to ensure accurate and up-to-date data. There are several ways in which providers can report data to PhilaVax.

  • Reporting Methods

    Electronic Reporting

    There are two different data sources and methods of reporting data to KIDS Plus IIS electronically:

    1. Electronic Medical Record (EMR) or Billing extract: Data is extracted from a billing, EMR or EHR system, .CSV, .XLS and .TXT formatted files are submitted to KIDS Plus IIS via the Philadelphia Secure File Transfer Protocol (SFTP) Website. Click here for more information on reporting requirements.
    2. Electronic Medical Record (EMR) Health Level 7 (HL7) reporting: Data is formatted in HL7 messaging format and transmitted to KIDS Plus IIS through SFTP or SOAP web services. KIDS Plus currently supports HL7 v2.5.1 batch, real-time uni-directional and bi-directional messaging. Click here for more information on HL7 reporting and meaningful use.

    Electronic reporting has several advantages over manual reporting, primarily the reduction in workload on the provider compared to manual reporting. In addition, there is virtually no delay from submission of data to entry into the KIDS Plus IIS, resulting in rapid access to data for reports and patient search.

    Manual Reporting

    This method requires data submission by paper reporting forms either via secure fax to 215-238-6944 or by mail to KIDS Plus IIS. 500 S. Broad St. 2nd Floor Philadelphia Pa, 19146. There are three types of logs used to report data to the KIDS Plus IIS:

    1. Influenza Reporting Form
    2. 0 – 18 Reporting Form
    3. Adult Reporting Form
