Needle Free Delivery Of Dengue And Zika Vaccines To The Skin

Funding Amount
$642,792.00
Summary
There is no Zika vaccine and only one licensed dengue vaccine, which is age and region restricted because of poor efficacy. We have developed safe subunit vaccine candidates capable of inducing potent virus neutralizing antibodies and demonstrated protection from lethal dengue challenge in a mouse model. Here we are partnering with Vaxxas to undertake preclinical development and GLP toxicity trials for microarray patches delivering dengue and zika virus subunit vaccines.
Prophylactic Vaccine Development For The Elimination Of Hepatitis C

Funding Amount
$936,752.00
Summary
A vaccine that prevents Hepatitis C is urgently needed to prevent infection and assist with global HCV elimination targets. This project grant will advance world-leading HCV vaccine candidates that generate both humoral and cellular immunity for clinical development.
Novel HIV-1 Glycoprotein Vaccines With Enhanced Presentation Of Broad Neutralization Epitopes

Funding Amount
$743,682.00
Summary
A prophylactic vaccine represents the best strategy for blocking HIV-1 transmission but one is not yet available. Current antiviral vaccines rely on neutralizing antibodies (NAbs) that block infection, however, current HIV-1 vaccine formulations do not induce broadly reactive NAbs (bNAbs). We have discovered a novel HIV-1 glycoprotein vaccination candidate with enhanced presentation of bNAb epitopes. We propose to determine if this vaccine induces effective bNAbs in experimental animals.
A Novel Vaccine Platform For Trimeric Envelope Proteins: HIV-1 Envelope

Funding Amount
$139,250.00
Summary
Vaccines are urgently needed for the prevention of HIV/AIDS. The design of this vaccine candidate is based on the display of HIV-1 envelope spikes using a related primate retrovirus envelope with a more stable assembly to anchor the the spikes in a particle.
Resolving Human Immunodeficiency Virus (HIV) Transmission

Funding Amount
$745,213.00
Summary
To increase the breadth of HIV prevention strategies, it is imperative that we biologically understand how HIV enters our bodies. Through two unique clinical cohorts, we will determine why circumcision is protective and how a commonly acquired sexual transmitted infection (human papilloma virus) can increase HIV transmission.
Intrinsic Host Antiviral Activity Against Pathogenic Filoviruses

Funding Amount
$488,754.00
Summary
Bats are a major reservoir for deadly human viruses including Ebola and Marburg virus. In contrast to humans, bats can be infected with these viruses without showing clinical signs of disease. The reason why bats can co-exist with these viruses is unknown. This study will determine if a bat antiviral molecule contributes to limiting virus release compared to the human version that could reveal strategies to prevent and control these deadly viruses in humans.
Identification Of Host Factors That Restrict Influenza Virus Replication In Macrophages

Funding Amount
$566,446.00
Summary
Influenza virus infects different cells in the airways, including immune cells (macrophages) and non-immune cells (epithelial cells). Epithelial cell infection results in virus amplification and release whereas macrophage infection leads to virus destruction. This project will identify cellular factors expressed by macrophages that block virus amplification and release. Identification of novel antiviral factors is an important step towards developing strategies to reduce influenza disease.
Identification Of Host Restriction Factors That Block Respiratory Virus Infection

National Health and Medical Research Council
Funding Amount
$956,898.00
Summary
Following inhalation, respiratory viruses can infect and grow in airway epithelial cells. Although immune cells such as macrophages are also susceptible to infection, this is generally abortive and new viruses are not released. This project will identify proteins induced in macrophages that block respiratory viruses and prevent their spread in the airways. We will also define mechanisms by which some virulent strains overcome this block to grow in macrophages.
The Role Of Varicella Zoster Virus In Modulating Cutaneous Infection

Funding Amount
$555,892.00
Summary
Varicella zoster virus (VZV) causes two skin diseases: chickenpox and shingles. VZV can causes significant morbidity in children and adults and life-threatening disease in immunocompromised people. This project aims to improve our understanding of how VZV affects the function of specialised skin cells to provide information for the development of a better vaccine to lessen the impact of VZV disease on the community.
