A separate trial showed that the drug reduced the risk of severe Covid-19 or death by 88% when administered within three days of the onset of symptoms.

“This new data adds to the growing body of evidence supporting the potential of the AZD7442 … We are in the process of regulatory applications around the world and look forward to offering an important new opportunity against SARS-CoV-2. [Covid-19] as quickly as possible,” AstraZeneca Executive Vice President Mene Pangalos said in the statement.

The Anglo-Swedish company has agreed to supply the US government with 700,000 doses of AZD7442 if the Food and Drug Administration provides it emergency aid, which AstraZeneca requested on 5 October. The company has similar agreements with other nations.

The drug is created using a combination of two antibodies derived from immune B cells donated by a recovering Covid-19 patient.

The treatment can be used for people who are known to not respond well to vaccines, such as cancer patients. About 2% of people are considered to be at risk of not producing enough antibodies after administering a Covid-19 vaccine.

Based on the numbers, the drug appears to be more effective than the company’s first-generation Covid-19 vaccine. The UK’s Zoe Covid study showed that the effectiveness of the vaccine dropped to around 67% after four to five months.
