Kramski had partnered with Australian biotechnology company Immuron Ltd to develop the milk, and would continue working with them to produce a preventative cream.

“We have the antibodies at the moment — the next step will be formulation,” Kramski said.

Condoms were “cheap and easy” but not an option for everyone with millions of people getting infected with HIV every year, she added.
