Human COVID vaccine trials begin in Australia. US biotechnology company Novavax says a proven vaccine could be ready by the end of the year.
A COVID-19 vaccine trial involving 131 volunteers across Melbourne and Brisbane is underway, with the aim of testing its safety and monitoring early signs of effectiveness.
US biotechnology company Novavax is starting human trials of a coronavirus vaccine in Melbourne and Brisbane, with 131 volunteers to test its safety and look for early signs of its effectiveness.
Novavax has begun the first phase of the trial in which 131 volunteers in Melbourne and Brisbane will test the safety of the vaccine and look for early signs of its effectiveness.
Most of the shots in the pipeline aim to train the immune system to recognize the “spike” protein that studs the coronavirus’ outer surface, priming the body to react if it ever encountered the real infection.
Still, other vaccine candidates are more old fashioned, made with the killed whole virus.
Novavax adds another new kind to that list, what’s called a recombinant vaccine.
The company used genetic engineering to grow what it says are harmless copies of the coronavirus spike protein in giant vats of insect cells in a laboratory.
Scientists extracted and purified the protein, and packaged it into virus-sized nanoparticles.
It’s the same process Novavax used to create a nanoparticle flu vaccine that recently passed late-stage testing.
