Professor Frazer's prediction is that the most likely candidate will be a vaccine that uses a part of the virus attached to a chemical to induce an immune response, or "subunit" vaccine.
"That [vaccine type] has been successful in animal models for coronaviruses in the past and that is of course where the money is being put in large measure at the moment," he said.
"Another sort of vaccine would be just antibody transferred from somebody who had been infected already and had got rid of the infection.
"Which would be an immunological means of preventing infection, and could probably be more quickly developed than an actual vaccine."
This sort of vaccine was tested with SARS in 2003 and resulted in reinfected lab monkeys having a nasty immune response, which is why many groups working on a vaccine for Sars-CoV-2 are going for a very specific antibody response.
