Questions and answers about COVID-19 vaccines
The Vaccine Education Center (VEC) at the Children's Hospital of Philadelphia (CHoP) has recently launched a new resource page answering common questions related to the development and safety of COVID-19 vaccines. Readers are also encouraged to submit their own questions directly to the VEC team for response.

New immunisation reference page: Vaccine development and safety
In an effort to promote confidence in the safety and efficacy of immunisation, MVEC has looked at the steps undertaken by vaccine candidates prior to being registered for use in vaccination programs. Post-licensure surveillance programs are also important for the early detection of any unexpected safety signals that may arise.

COVID19 Road to a vaccine episode 6: Professor Paul Offit
In episode 6 of our COVID19 Road to a vaccine series, our host, Associate Professor Nigel Crawford, speaks to Professor Paul Offit. Professor Offit is an infectious diseases physician and Director of the Children's Hospital of Philadelphia (CHoP) Vaccine Education Center (VEC). The VEC website inspired the creation of the Melbourne Vaccine Education Centre, the host of this podcast series.
In this episode they discuss:
- The impact of SARS-CoV-2 on health care workers and the importance of a vaccine
- Preventative therapies and randomised controlled trials in a pandemic, specifically the use of hydroxychloroquine for COVID-19 and the other trials involving health care workers
- COVID-19 in children - do they play a role in transmission? Will they be a target for vaccine studies?
- Paediatric Inflammatory Multisystem Syndrome (PIMS) - how can we factor this emerging condition into safety planning?

COVID19 Road to a vaccine episode 5: Professor Terry Nolan
In episode 5 of our COVID19 Road to a vaccine series, our host, Associate Professor Nigel Crawford speaks to Professor Terry Nolan. Professor Nolan is a Redmond Barry Distinguished Professor at the Doherty Institute for Infection and Immunity. He heads up VIRGO, the vaccine and immunisation research group, a collaboration between Murdoch Children's Research Institute and the University of Melbourne. VIRGO has the largest and longest standing child and adolescent vaccine population research and clinical trials program in Australia. He previously chaired ATAGI, the Australian Technical Advisory Group on Immunisation and was a member of SAGE, the World Health Organisation's main advisory group on vaccines and immunisation. They discuss the COVID-19 candidate vaccines from an Australian perspective and Australia's role in global clinical trials.

COVID19 Road to a vaccine podcast episode 4: Professor Kanta Subbarao
In episode 4 of our COVID19 Road to a vaccine series, our host, Associate Professor Nigel Crawford, will be speaking to Professor Kanta Subbarao. Professor Subbarao has been the Director of the World Health Organisation Collaborating Centre for Reference and Research on Influenza since 2016, based at The Doherty Institute at the University of Melbourne, Australia. She is a virologist and physician who specialises in paediatric infectious diseases. Her research is focused on influenza, as well as newly emerging viral diseases of global importance such as SARS and MERS, which includes immune responses to infection and vaccination.
In this episode they discuss:
- The specific virus characteristics of SARS-CoV-2
- How the biosafety laboratory at VIDRL (Victorian Infectious Diseases Reference Laboratory) were able to culture the SARS-CoV-2 virus and distribute their findings globally
- The origin of coronaviruses and why this pandemic strain is different
- The spike protein and the important role antibodies play in the development of a SARS-CoV-2 vaccine
- Immunological principles in the development of a SARS-CoV-2 vaccine
- How to determine an antibody is functional and protective
- The likelihood of SARS-CoV-2 changing over time

Flu deaths prevented as cases plummet amid coronavirus lockdowns, AMA says
New data as reported by the ABC suggest that social distancing measures, reduced travel and other restrictions implemented in the COVID-19 pandemic appear to have resulted in a sharp decline in the number of influenza cases.
Dr Chris Moy of the Australian Medical Association is careful to note that we may have actually delayed an influenza outbreak, but still believes the number of influenza cases will be less as we have a far more immunised population this year.
