Summary
A major obstacle in the development of effective vaccines to protect against bird flu (avian influenza) is the difficulty in producing enough vaccine in a short enough time to be able to protect the population should bird flu become a problem in the human population. Our research is focused on a technique to make vaccines much more effective and thereby reduce the amount of vaccine needed for each person. This would allow many more people to be protected with the same amount of vaccine.

Our research is focused on a technique to make vaccines much more effective and thereby reduce the amount of vaccine needed for each person. This would allow many more people to be protected with the same amount of vaccine. This technology is known as a vaccine adjuvant and we have developed a unique adjuvant based on a natural plant sugar called inulin that has the potential to dramatically enhance existing and new flu vaccines.Read moreRead less

The Genetic Understanding of Asbestos-Related Disorders (GUARD) project aims to establish a national facility that will enable new, large-scale DNA banking capacity for malignant mesothelioma (MM) and other asbestos-related diseases. The GUARD biospecimen resource and linked database will integrate the current WA population-based asbestos-exposed cohorts with case collections from across Australia. The GUARD project will undertake high-quality research aimed at discovering the genes and gene: environment interactions underlying susceptibility, progression and variable response to chemotherapy in mesothelioma, and will facilitate National collaboration and research in the areas of genetic epidemiology and pharmacogenomics. Progress towards the goals of the GUARD project holds the potential for enormous public health benefits; the incidence of malignant melanoma is increasing, due to the long delay between asbestos exposure and diagnosis. GUARD will ensure that Australian researchers have access to a large and well-managed biospecimen resource linked to excellent clinical data, and that Australia takes the lead role internationally in genetic research into mesothelioma. GUARD data will be critical for understanding the importance and functional roles of specific genes in the general Australian population, and their relationship to particular environmental factors. Understanding how causal factors act at a population level will be a critical step for the clinical utilization of new genomic knowledge and tools to improve clinical practice and public health.Read moreRead less

These particular avian flu viruses are capable of causing severe disease and death in humans as well as birds, although at present they are not highly transmissible between people. Should the avian influenza viruses mutate to gain this capability, it will be necessary to institute widespread vaccination of the Australian population. It is not possible to test the vaccines in people for their effectiveness against avian influenza infection prior to a disease outbreak, so an animal model for the disease will be used to assist in optimizing the formulation of flu vaccines and in testing their efficacy in preventing infection or reducing the severity of disease. Ferrets are natural hosts for flu viruses, have similar responses to vaccination as people, and develop a similar disease to humans when infected with influenza. These animals will be used to assist vaccine manufacturers in providing the best type of vaccine for protection of Australians in the face of a global flu pandemic.Read moreRead less

Tests such as reverse transcription polymerase chain reaction (RT-PCR) are in use globally for influenza A H5N1 detection. Some proprietary rapid influenza A tests also claim to detect influenza A H5N1. However there is little information on systematic evaluation of these, largely because there have been relatively few human influenza A H5N1 cases and patient specimens. Australian laboratories need authoritative guidelines as to optimal influenza tests, target genes and reagents. Development of a simple, potentially automated type specific test for influenza A H5N1 antibody such as enzyme immunoassay (EIA) is also desirable, as widely used tests cannot distinguish between infection with H5 or other influenza types. Reference methods such as haemagglutination inhibition (HAI) are cumbersome. In this project mock specimens for virus and antibody detection will be created using viral cell culture and infected chicken derived influenza A H5N1. This will be undertaken in physical containment level 4 (PC4) facilities in Australia's designated human and animal PC4 laboratories. This material will be used for (i) specimen panels to compare the performance of candidate laboratory tests (ii) positive control material in all tests undertaken and (iii) quality assurance exercises to ensure high standards of testing. Using these panels the group will assess influenza H5N1 RT-PCR, tests for detection of influenza proteins including immunofluorescence, and rapid point of care influenza A detection tests available in Australia. An EIA method currently used to detect influenza antibodies from different animal species will be refined to develop a simple test for type specific detection influenza A H5N1 antibodies, and subsequently evaluated using animal sera. A standard method for HAI reference serology for use in public health laboratories will also be recommended, and the best approaches to high throughput automated RT-PCR, and performing RT-PCR in the field on portable instrumentation will be explored. Recommendations for standard protocols for influenza A H5N1 will be developed and will submitted for review and endorsement by Commonwealth ministerial advisory committees.Read moreRead less

We have developed a novel VLP system that allows the production of VLPs containing foreign vaccine antigens of much larger size than previously possible, and have shown that these VLPs provoke strong immune responses in mice without the use of adjuvants. The capacity of these VLPs is large enough to accommodate the most important vaccine antigen of influenza, the haemagglutinin (HA) molecule. We will test whether VLPs can be produced containing each of the three most important HA types _ H1 and H3 that are currently circulating in man, and H5 (avian) that is considered a pandemic threat. VLPs will be tested for their ability to induce neutralizing antibody and cellular immune responses in mice, and for their ability to protect ferrets from influenza infection. If successful, the HA-VLP system would provide a method for the rapid production of new influenza vaccines using large-scale fermentation technology as for hepatitis B and many other vaccines, rather than eggs or cell culture as used for current influenza vaccines.Read moreRead less

As of August 2005, the highly pathogenic Avian Flu sweeping through Asia has infected 112 people, killing 57. Over 150 million chickens have been slaughtered in an attempt to stop its spread, but with infection documented in migratory birds, containment may be difficult if not impossible. Experts believe that it is only a matter of time before the Avian Flu virus is capable of human to human transmission which could result in the deaths of hundreds of thousands of people worldwide. Should a pandemic arise, either through purposely-engineered or natural processes such as avian influenza, effective vaccines are unlikely to be available for at least 3-6 months. In such an event, treatment of infection and prevention of spread through post-exposure prophylaxis would be optimal, while pre-exposure prophylaxis would be most suited to key personnel such as army, medical and emergency-response staff. Biota is a world leading antiviral drug discovery company based in Melbourne, Australia with key expertise in viral respiratory diseases, particularly influenza. Biota developed the first in class neuraminidase inhibitors (NAI) drug, zanamivir (Relenza) and through a partnership with Glaxo Smith Kline (GSK) brought it to market. Biota also developed the FluOIA� for the rapid detection of Influenza A and B. Work has been underway at Biota for some time to develop a new generation of influenza drugs designed to be more active and longer acting than the first generation products. These long acting neuraminidase inhibitors (LANI) have the benefit of less frequent administration and a lower treatment dose making them an ideal choice for stockpiling. The proposed project aims to test the antiviral activity of LANI compound against the H5N1 influenza. The results of which could assist in a decision to fast track the clinical development of the compound with the aim of adding to the national stock pile of antivirals, thus helping Australia to prevent, prepare for and respond to a potential avian influenza-induced pandemic.Read moreRead less

Summary
Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around ....Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around the edges of masks, particularly if it fits poorly, and also a small percentage can pass through the filter material. While influenza is usually not a major health problem in the general community, the emergence of a more hazardous strain will place an additional burden on health care and other facilities, and requires the development and optimization of measures to minimize virus spread and protect those who are exposed. The aim of this project is to build small filters that can be worn in the nose to provide additional filtration of inhaled air. These filters would be worn in combination with a mask in high exposure circumstances, such as by health care workers when treating infected patients or could be used when a mask was not normally worn to provide effective and discreet protection, such as in crowded public places. Developing such filters builds on our experience of making small samplers worn in the nose to measure allergen exposure. This experience is combined with advanced filter materials developed by leading US researchers that permit the efficient filtration of particles as small as viruses. This project will be conducted in collaboration with a leading Australian design group, and we will design and evaluate such filters for their ability to capture virus and thus protect the wearer. The filters should provide an intuitive, effective and inexpensive method to be used in combination with other hygiene measures to increase personal protection from acquiring highly transmissible respiratory diseases, particularly influenza. We expect to have prototypes of the filters available in 6 months so that production can commence.Read moreRead less
