Partners
AHW participates in a bulk purchase program with all jurisdictions in Canada facilitated by PHAC
AHW then distributes this vaccine to Regional Health Authorities (RHAs)
Physicians are important partners in the delivery of publicly funded influenza vaccine in Alberta
Physicians can order influenza vaccine from RHAs for patients eligible for publicly funded vaccine

Partners
The proportion of publicly funded vaccine delivered by physicians varies between RHAs in Alberta. Approx. 50% delivered by PH staff Approx 50% delivered by physicians who see
patients with a chronic illness

Reporting Adverse Reactions
Surveillance of ALL influenza vaccine-associated events with no enhanced surveillance of ORS
Use Report of Adverse Reaction to Immunizing Agents form (Jan. 2004)
Physicians would either complete this form or direct their patients to public health for follow-up
![Page 18: 1 Alberta’s Influenza Immunization Program TARRANT Workshop Elaine Sartison AHW March 24 2007.](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649c925503460f9494ceef/html5/thumbnails/18.jpg)

NACI Statement on ORS
It is safe to re-immunize individuals who have experienced Mild or moderate ORS symptoms Severe ORS symptoms without lower respiratory
symptoms Consultation with the local MOH for those
who experienced severe ORS symptoms with lower respiratory symptoms within 24 hours of receiving influenza vaccine.

Hot Issues
Why thimerosal-reduced and thimerosal-free used even though not considered a risk? Theoretical risk – follow the precautionary
principle to reduce exposure Maintain public confidence in vaccines What other jurisdictions in Canada
are providing
![Page 21: 1 Alberta’s Influenza Immunization Program TARRANT Workshop Elaine Sartison AHW March 24 2007.](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649c925503460f9494ceef/html5/thumbnails/21.jpg)
21
Hot Issues, continued
Vaccine supply for the private market Solvay Pharma Inc Belgian based pharmaceutical Provided to some provinces last flu season Influvac
Some product confusion – licensed for adults only
Vaccine supply for provincially funded programs late two consecutive years Delayed influenza program to November 1st
![Page 22: 1 Alberta’s Influenza Immunization Program TARRANT Workshop Elaine Sartison AHW March 24 2007.](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649c925503460f9494ceef/html5/thumbnails/22.jpg)
22
Future Considerations
• provision of information for physicians to give to patients
• timely delivery of vaccine to physician’s offices
• availability of vaccine for the whole influenza season pending vaccine supply issues
• provincial electronic health record so physicians’ can access immunization information (influenza may not be included for all regions)
![Page 23: 1 Alberta’s Influenza Immunization Program TARRANT Workshop Elaine Sartison AHW March 24 2007.](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649c925503460f9494ceef/html5/thumbnails/23.jpg)
23
Possible Best Practices:
• consider the physician’s office as an important access site
• provide annual information on the vaccine and vaccination program for physicians
• provide multiple/additional public health clinic sites
• other providers of influenza vaccine should be connected to public health
