The COVID vaccine will become increasingly sophisticated. Vaccines without injections are now beginning to be tested. If not injected, how does the vaccine get into the body?
This non-injectable COVID vaccine trial is being conducted in Australia. The COVALIA phase 1 vaccine trial was held simultaneously at 3 sites, namely Scientia Clinical Research in Sydney, Telethon Kids Institute in Perth, and the Women's and Children's Hospital in Adelaide.
This gene-based vaccine uses the DNA sequence of the SARS-CoV2 virus. Reported from News.com Australia, Tuesday (29/6/2021) this vaccine does not use injection, but jet spray or high pressure spray.
When sprayed with high pressure, the vaccine will penetrate the skin. The vaccine will be absorbed by the body's cells. The DNA code will produce proteins that trigger the body's immunity.
The technology for this spray vaccine has been used in America, but has only been tested in Australia. The trial was led by the University of Sydney.
The COVALIA vaccine was designed by the biotechnology company Technovalia and its partner BioNet which developed the DNA vaccine.
In the first phase of the experiment, 150 volunteers are needed. Each person is given 2 doses of the vaccine with an interval of 1 month. If successful, it will continue with phase 2.
"The COVALIA study is an important milestone," said lead researcher at the University of Sydney, Nicholas Wood.
Meanwhile, researcher from the Telethon Kids Institute, Peter Richmond, says it is important to develop a COVID-19 vaccine for better immune response and safety for everyone.
"Providing a more diverse vaccine model will improve the global vaccine's ability to ensure that everyone can be immunized," he said.
