LONDON – A third COVID-19 vaccine has turned in positive results in the phase III interim analysis, with Astrazeneca plc/Oxford University reporting an average of 70.4% efficacy across two dose regimens for AZD-1222.
In what the FDA calls “an incremental step” in treating hospitalized COVID-19 patients, the agency has issued an emergency use authorization (EUA) for Eli Lilly and Co.’s baricitinib in combination with remdesivir.

In a world more familiar with the 30% to 70% efficacy rates of seasonal flu vaccines, news of 95% efficacy rates for two of the major late-stage COVID-19 vaccines in development seems thrilling. But do such robust-sounding numbers, the product of relatively early analyses, really merit the enthusiasm they’ve garnered?
Regulatory snapshots, including global drug submissions and approvals, clinical trial approvals and other regulatory decisions and designations: ADC, Alexion, Amgen, Astrazeneca, Beigene, Biontech, Eli Lilly, Gilead, Immupharma, Pfizer.
