    AstraZeneca’s CEO says the firm is likely to conduct another global trial of the Oxford coronavirus vaccine after US officials raised questions about its effectiveness. Bloomberg revealed the new trial would evaluate a lower dosage that performed better than a full dosage. A US official claimed the dose of the vaccine – which shown to be highly effective – has only been tested in people aged 55 and under. Scientists also questioned a lack of detail in the trial results put out by the company last week.
