World Hepatitis Day, observed annually on 28 July, is just around the corner and aims to raise awareness of the virus that’s responsible for more than one million deaths a year.
But what is hepatitis and what’s the difference between strains A-E? What are researchers doing to find a cure for the most common strain, hepatitis B?
Discover answers to these questions and more from Professor Peter Revill, Head of Regional and Global Health at the Victorian Infectious Diseases Reference Laboratory and Head of International Research Partnerships at the Doherty Institute.

Influenza B viruses are often overlooked but can cause significant illness and mortality, especially in children. Little is known about how the immune system interacts with these viruses, however a recent breakthrough by researchers at the Doherty Institute may revolutionise how we are protected against influenza B and for longer periods.
Tejas Menon, co-author of the recent discovery and PhD Candidate at the Doherty Institute, explains how the immune system consistently recognises fragments of influenza B viruses, which opens up potential new targets for vaccine development.

Does your immune system remember viruses you've previously been infected with? Do your genetics play a role in your immune system? Can you boost immunity with certain foods or vitamins?
Ahead of the International Day of Immunology (April 29) we chat with Nobel Laureate Professor Peter Doherty to answer these questions and more, unravelling the complexities and exploring the wonders of our body's line of defence against disease; our immune system.

From protecting local communities to safeguarding global health, vaccines have been transforming public health for over 200 years. According to the World Health Organization, between 3.5 and 5 million lives are saved every year thanks to vaccines, which help protect us from diseases such diphtheria, tetanus, pertussis, influenza and measles.
Professor Arup Chakraborty, a luminary from the Massachusetts Institute of Technology joins the podcast ahead of the Miegunyah Distinguished Fellowship Public Lecture 'Vaccination through the ages' on Monday, 25 March at the Doherty Institute.
We take a dive into the fascinating world of vaccines; from their historical roots to the cutting-edge science shaping our future.

Despite being vaccine-preventable, outbreaks of measles are currently occurring in every region of the world, with many countries reporting their first case in years. In Australia, the disease was considered eliminated in 2014, but a series of imported case alerts begs the question – do we need to be concerned?
To shed some light on the situation where we're seeing cases of measles on the rise globally, we speak with The Royal Melbourne Hospital’s Dr Katherine Gibney, an infectious diseases and public health physician, and medical epidemiologist at the Doherty Institute.

Legionnaires’ disease made headlines in Australia at the beginning of the year due to an outbreak of the lung infection in Sydney’s city centre.
Fundamental to effective Legionnaires’ disease outbreak control is the ability to rapidly identify the environmental sources of the causative bacteria, Legionella pneumophila. Could artificial intelligence be the answer?
Dr. Andrew Buultjens is the lead author of a transformative study harnessing the power of machine learning to accurately pinpoint the origins of this bacteria.

The debilitating ‘flesh-eating’ infection that is Buruli ulcer has captivated Victorians in particular over the last 10 years or so, due to its increasing incidence in the state. Mosquitoes have been considered likely to be involved in transmission of the bacteria, Mycobacterium ulcerans, conclusive evidence about how humans get infected has been elusive, until now.
University of Melbourne Professor Tim Stinear, molecular microbiologist and Director of the WHO Collaborating Centre for Mycobacterium ulcerans at the Doherty Institute, explains the latest groundbreaking findings into the transmission of the neglected tropical skin disease.

While much of our attention has been on COVID-19 over the last few years, another pandemic has reeked havoc on more than 200 species of wild birds. The spread of H5N1 or bird flu as its more commonly known, to migrating birds has seen substantial outbreaks occur in Europe, Asia, Africa, North America and South America. As this podcast goes to air, there’s been at least one suspected case in Antarctica.
Expert in the wild bird viruses, Dr Michelle Wille, explains why this could be catastrophic.

In a major coup for the Doherty Institute and the Monash Institute of Pharmaceutical Sciences, our two COVID-19 vaccines went head to head in a Phase 1 clinical trial in 2022. The interim results have just been published in the Lancet’s eBioMedicine journal and found that both have strong potential to be an improved approach for boosting immunity to SARS-CoV-2 variants.
In this episode we unpack the interim results from the trial with Professor Terry Nolan. Terry is a paediatrician and clinical epidemiologist. He is also the Head of the Vaccine and Immunisation Research Group at the Doherty Institute and Murdoch Children’s Research Institute, which led this Phase 1 clinical trial.

Our immune system is made up of many types of cells. Many people will have heard of T cells that fight infection, but did you know there are many different subsets of T cells?
In this episode we're talking all things tissue-resident memory T cells with the author of a new study that has found new ways to remove immune cells that cause skin autoimmune diseases, like psoriasis and vitiligo, without affecting protective cells that fight infection and cancer.
Dr Simone Park is an immunologist who holds an Honorary position at the Doherty Institute after completing her PhD with Professors Thomas Ghebhardt and Laura Mackay, and is currently a Cancer Research Institute Postdoctoral Fellow at the University of Pennsylvania in Philadelphia. Her work aims to understand how the immune system responds to infection and cancer.

Antimicrobial resistance has consistently been named by the World Health Organization as one of the top 10 global health threats, with current estimates of over 700,000 deaths per year due to antimicrobial resistance, expecting to reach 10 million by 2050.
Antimicrobials refer to a category of medicines used to prevent and treat infections in humans, animals and plants including antibiotics, antivirals, antifungals and antiparasitics. So what exactly is antimicrobial resistance? What is causing it to become increasingly worse? And what can be done to prevent it? To answer these questions we're joined by Medical Microbiologist, Dr Rod James.
