Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Trivalent Inactivated Influenza Vaccine 6 months to 2 years post transplant as per immunisation guidelines. Two doses of influenza vaccine at least 4 weeks apart are recommended for all HSCT recipients receiving influenza vaccine for the first time, with the 1st dose given as early as 6 months post transplant. This is given intramuscularly.
Intervention code [1] 288814 0
Prevention
Comparator / control treatment
comparing immunogenecity to healthy controls who will be given the vaccination as per the Australian immunisation guidelines. This means that children who are influenza vaccine naive and under 10 years of age will have two doses and the others will have one dose of the vaccine given intramuscularly.
Control group
Active

Outcomes
Primary outcome [1] 291505 0
To measure influenza specific Haemagglutinin Inhibition [HI] antibody levels by standarised method at WHO Collaborating Centre for Reference and Research on Influenza
Timepoint [1] 291505 0
for one dose, prevaccinetion and between 4 to 8 weeks post dose.
For two doses, prevaccination and between 4 to 8 weeks post each dose.
Secondary outcome [1] 306918 0
To identify the frequency and severity of microbiologically confirmed influenza illness in HSCT patients who received TIV during that influenza season. This is assessed by asking the patients to contact staff if they have an influenza like illness. If they fulfil the criteria, then they come in for medical assessment and nasal swab looking for respiratory viruses by IF +/_ PCR. If positive for influenza, the swab will be sent to WHO Collaborating Centre for Reference and Research on Influenza for specific strain typing to assess vaccine failure versus strain mismatch.
Timepoint [1] 306918 0
Any time from enrolment to end of the influenza season (End of nov of enrolment year)
