A Time-motion Study Comparing Self- to Nurse-vaccination With Influenza Vaccine

A Time-Motion Study to Compare Self-vaccination With Intanza® Intradermal Influenza Vaccine to Nurse-administered Vaxigrip® Intramuscular Influenza Vaccine in Small Group Settings of Health Care Workers

The investigators hypothesize that people working in an acute care hospital setting will be able to successfully self-administer the intradermal vaccine (Intanza) in less time than nurse-administration of the regular intramuscular influenza vaccine (Vaxigrip). The investigators also hypothesize that people administering the intradermal vaccine for the second time will take less time to successfully administer than people administering it for the first time.

Vaccination of healthcare workers has been shown to reduce mortality and morbidity in the patients they care for, as well as reducing illness and absenteeism in the healthcare workers themselves, and healthcare worker vaccination programs have been shown to be cost-effective for hospitals because of the reduced absenteeism. Although influenza vaccination programs based on nurse-administered intramuscular vaccination are effective, easy access to vaccination for hospital staff remains a challenge, in part because of large numbers of staff working evening, night and weekend shifts. In addition, in the Canadian setting, increasing the efficiency of all hospital programs is a priority. If regular recipients of seasonal vaccine became accustomed to the practice, self-administration may significantly improve the efficiency of pandemic mass vaccination campaigns.

• Able to read, understand, and respond to questionnaires
• Able to read, understand, and sign an informed consent form
• Available for follow-up for 8 days post-vaccination
• Participants in Part B (repeat administration) of the study must also have participated in the previous randomized control trial of self- versus nurse-administered intradermal influenza vaccine and must have attempted to self-administer the vaccine
