In June, some of his colleagues published a report suggesting that, because of the way it binds to proteins in blood plasma, the drug would need to be given at high concentrations to achieve an antiviral effect in humans2. “These very high doses would carry a risk of adverse effects that would be unacceptable,” he says.
