Ryan also said that even if antibodies were effective there was little sign that large numbers of people had developed them and were beginning to offer so-called “herd immunity” to the broader population.
“A lot of preliminary information coming to us right now would suggest quite a low percentage of population have seroconverted (to produce antibodies),” he said.
“The expectation that … the majority in society may have developed antibodies, the general evidence is pointing against that, so it may not solve the problem of governments.”
