Examining immune response to flu vaccination among hospital workers
Why this study 

Healthcare workers are advised to receive annual seasonal influenza vaccine to protect staff and patients from infection. Some evidence suggests antibody responses to influenza vaccine may decrease with repeated vaccination; however, little is known about how this occurs.

What do we want to achieve

To study how the immune system and effectiveness of the vaccine is influenced by prior vaccination experience.

How are we doing it

We are participating in a multi-centre study conducted by the WHO Collaborating Centre for Reference and Research on Influenza. Healthcare workers are recruited prospectively during influenza vaccination campaigns. Immune responses to the influenza vaccine and infection are determined through blood testing. Participants are followed up and tested via a nasal swab to establish whether they develop influenza illness.
