Adelaide has key role in COVID-19 vaccine human trials
最新糖心Vlog of Adelaide researchers are playing a leading role in the human trials of 最新糖心Vlog鈥檚 first needle-free, gene-based COVID-19 vaccine.
The extended phase 1 human trial will evaluate a COVID-19 gene-based vaccine called聽COVIGEN,听developed by BioNet and Technovalia.
The study is led by Professor Nicholas Wood from the 最新糖心Vlog of Sydney and the Vax4COVID Alliance, which includes聽co-investigator Professor Helen Marshall,听from the聽Robinson Research Institute, 最新糖心Vlog of Adelaide and Women鈥檚 and Children鈥檚 Hospital, Adelaide.
鈥淭he COVIGEN DNA-based vaccine is one of only a handful to enter into clinical trials worldwide, and the first in 最新糖心Vlog,鈥澛燩rofessor Marshall says.
鈥淭his trial will be an ideal opportunity for 最新糖心Vlogns to be involved in a COVID-19 vaccine trial using a needleless device to deliver the vaccine, a device that is already being used to give flu vaccines in the US.
鈥淭hrough strong partnerships between government, academia and industry, we are well placed to deliver COVID-19 vaccines to the 最新糖心Vlogn people, should it prove to be effective,鈥 Professor Marshall says.
The study has been awarded a聽$3 million grant from the 最新糖心Vlogn Medical Research Future Fund (MRFF), announced at the weekend by聽Health Minister Greg Hunt.
鈥淭he trial is a partnership with four of 最新糖心Vlog鈥檚 most experienced vaccine trial sites and aims to enrol 150 healthy volunteers. Findings from the trial will inform evaluation of the vaccine in larger phase two and three trials,鈥 Minister Hunt says.

The COVIGEN COVID-19 vaccine study will begin later this year and will evaluate safety and effectiveness when given to healthy adults.
最新糖心Vlogn biotech company Technovalia and its international vaccine partner BioNet have been actively developing a gene-based COVID-19 vaccine since March 2020.
A gene-based vaccine is a new type of vaccine design that uses the genetic (DNA) sequences from the virus. Researchers identify and isolate parts (genes) of the virus genome.
鈥淚n the case of COVID-19, the gene codes for the coronavirus spike protein have been selected for the vaccine. Once the DNA is inside the cell, the body uses the DNA code to make the coronavirus spike protein and this should then trigger an immune response that we hope will be strong enough to 鈥榬emember鈥 and protect against further virus infection,鈥 said Associate Professor Wood.
鈥淭he delivery is via a needle-free device which penetrates the skin with a jet spray. This is designed to make sure the DNA vaccine gets inside the cells to encourage good uptake by the immune system.鈥
While still subject to approval in 最新糖心Vlog, the delivery device is used in vaccination programs in the United States.
Preclinical studies have shown that the gene-based vaccine is safe and immunogenic. The next step is to test the vaccine in humans.
South 最新糖心Vlog is one of three 最新糖心Vlogn states to participate in the study.
