    • Annual vaccine effectiveness estimation

      Influenza vaccines are updated twice annually to keep pace with the antigenic drift of the virus.  However, the production time of these vaccines is five to six months, leaving insufficient time to test vaccine efficacy. Sheena’s group works with the Australian Sentinel Practices Research Network (ASPREN), the sentinel practices network of WA (SPNWA) and the Victorian Sentinel Practices Influenza Network (VicSPIN at VIDRL) to provide annual estimates of influenza vaccine effectiveness for Australia. The group also works with collaborators around the world to compile these data into a report for use in vaccine strain selection.

    • Validity of vaccine effectiveness studies

      In recent years, there has been a dramatic increase in the number of countries reporting annual influenza vaccine effectiveness estimates using routine surveillance data. In these “test-negative” studies, patients presenting with influenza-like illness are recruited into the surveillance program, swabbed and tested for influenza. Vaccination status is recorded and those testing positive are compared with those testing negative to obtain an influenza vaccine effectiveness estimate. Sheena’s group has been working with colleagues within Australia and abroad to better understand the unique methodological issues associated with this study design.  

    • Serological responses to vaccination

      Many hospitals have a policy for achieving high influenza vaccination coverage among their staff.  However, the long-term effects of influenza vaccination are not well understood. Some evidence suggests that the antibody response to vaccination attenuates with repeated vaccination, and this finding is corroborated by epidemiological studies, which have indicated that the vaccine’s effectiveness is reduced among people who have been vaccinated repeatedly. Sheena’s group is undertaking studies at two Melbourne hospitals to estimate whether serological responses vary according to vaccination experience.

    • Brown Group

      Lorena’s group is dedicated to understanding different aspects of influenza virus structure and replication, as well as the host immune response to the virus that may impact on disease outcome. They study areas of vulnerability that can be targeted by vaccines and therapeutics to control seasonal and highly pathogenic isolates.


    • Deng Group

      While her team’s core task has always been on the molecular surveillance of influenza viruses and its methodology development, Yi-Mo’s group have been collaborating actively both within and outside the Centre on several research projects relating to the molecular characterisation and evolution of human or animal influenza viruses. 


    • Hurt Group

      Aeron’s research team at the WHO Collaborating Centre for Reference and Research on Influenza works on aspects of understanding the replication and transmission of drug resistant influenza viruses, characterising novel drug resistance mutations, and the global movement and evolution of human and avian influenza viruses.


    • Kedzierska Group

      Professor Katherine Kedzierska’s team researches the immunity to viral infections, especially the newly emerged influenza viruses. Her work spans basic research – from mouse experiments to human immunity, through to clinical settings, with a particular focus on understanding universal CD8+ T cell immunity to influenza viruses. Her studies aim to identify key correlates of severe and fatal influenza disease in high-risk groups including children, the elderly and Indigenous Australians.

    • Kent Group

      Stephen’s group studies immunity to HIV, influenza and SARS-CoV-2. They are analysing a variety of vaccine strategies, including nanoparticle-based vaccines. They are studying a series of immune responses to gain better insights into protective immunity to important viral pathogens. They are developing monoclonal antibody therapies for HIV, influenza and SARS-CoV-2 to improve the treatment of these infections. The Kent group works very closely with Dr Amy Chung’s laboratory at the Doherty Institute.

      Other work areas include:COVID-19, Immunology, HIV


    • Reading Group

      Patrick’s group investigates how the body first detects and responds to respiratory viruses. They investigate viral attachment factors, cellular receptors and entry pathways, virus-induced activation of host genes and the mechanisms by which intracellular host proteins can block virus replication.

    • Valkenburg Lab

      The Valkenburg laboratory investigates viral immunity to emerging viruses with pandemic potential: influenza viruses and SARS-CoV-2. Our work spans randomised control vaccine trials, observational studies of infected patients and animal models to decipher immune correlates to drive novel translational outcomes for specific diagnostics, targeted therapeutics and next generation vaccines for public health impact.

    • Wakim Group

      Linda’s group’s main research focus is understating the mechanism of action and regulation of expression of antiviral proteins. Linda’s group also aims to characterise CD8 T cell responses within the lung following virus infection. 

      Other work areas include:Immunology


    Clinical Research

    Anyone can be infected by influenza, but some people are more susceptible to infection, severe disease and clinical complications. Clinical studies at the Doherty Institute are focused on specific risk groups, seeking to understand characteristics of viruses and the immune system that result in increased susceptibility and clinical severity. In particular, current studies are considering:

    Doherty Institute researchers are also characterising immune responses to influenza vaccination or infection in various groups of people, including:
