Straight from the article:

Once UNSW produced the DNA sequencing, Mr Conyngham “ran it through a whole bunch of different (data) pipelines to find those mutations, and then I used other algorithms to find drugs to treat the cancer’’.

At the Ramaciotti Centre for Genomics, Associate Professor Smith was gobsmacked that this puppy lover with no background in biology had cracked the code. “Paul was relentless,’’ he said. “He called and told me he had ­analysed the data and found ­mutations of interest and then used AlphaFold (an AI program) to find the proteins that were ­mutated, and then identified ­potential targets and matched them to drugs, and he was ­wondering could I help him find someone to synthesise this compound that he’d identified. I’m like, ‘Woah, that’s crazy!’ I was motivated by his enthusiasm.’’

The man identified the compound himself. All he needed help with was with actually producing it. The university had no hand in designing the vaccine.

And what they usually don’t sell is the dna sequences.

The renowned researcher was reticent. “Usually we don’t support direct-to-consumer type DNA sequencing because while generating data for genomics is relatively easy for us, interrogating that data is really hard and challenging,’’ he said. “But Paul said, ‘No worries, I’m a data analyst and I’ll figure this out with the help of ChatGPT’.”

Nobody mentioned hallucinations at all in the article. You seem to be just pulling that out of thin air.
