Researchers were now planning to test the effectiveness and safety of the milk before turning it into a cream which will hopefully allow women to protect themselves against contracting the virus during sex, without relying on men, the Herald Sun reported.u00a0

However, the final result could be a decade off. The researchers were able to inhibit the virus from infecting cells when combing the virus cells with milk.u00a0

"We think the antibodies bind to the surface of the virus and blocks the protein which needs to be freed to get in contact with human cells - like a key and lock system.u00a0
