Despite experts raising doubts over the plasma therapy to treat Covid-19, the US Food and Drug Administration (FDA) has issued an emergency use authorisation (EUA) for convalescent plasma to treat the deadly respiratory disease.
In a statement on Sunday, the FDA said that "known and potential benefits of the product outweigh the known and potential risks of the product".
According to a CNN report, the FDA said more than 70,000 patients had been treated with convalescent plasma.

At a White House briefing on Sunday, President Donald Trump said: "Today, I am pleased to make a truly historic announcement in our battle against the 'China virus' that will save countless lives."

"Today's action will dramatically increase access to this treatment," the President said, adding that he has directed the FDA to approve the EUA for convalescent plasma therapy.
According to media reports last week, the FDA had put on hold the emergency use authorisation for blood plasma to treat Covid-19.
In a report, The New York Times said the FDA approval for plasma therapy was on hold and "more data is under review and the approval could still be issued in the near future, according to H. Clifford Lane, the clinical director at the National Institute of Allergy and Infectious Diseases".
Top health officials including Anthony Fauci, the country's top infectious disease expert, have cautioned that available data wasn't strong enough to support emergency approval.

The convalescent plasma therapy has gained much traction in several countries including India, where several lives have been saved with the therapy.
Trump later accused some health officials of playing politics regarding an emergency use authorisation for convalescent plasma.
When asked about the FDA not having granted an EUA, Trump said the "reason was political", the CNN report said.
US Health and Human Services Secretary Alex Azar, however, said studies involving 70,000 volunteers justified the move.
"The data we gathered suggests that patients who were treated early in their disease course, within three days of being diagnosed, with plasma containing high levels of antibodies, benefited the most from treatment.

"We saw about a 35 per cent better survival in the patients who benefited most from the treatment," Azar told the White House briefing.

The development comes as the US still accounts for the highest number of coronavirus cases and deaths in the world.
As of Monday morning, the overall number of cases stood at 5,701,557, with 176,797 deaths, according to the Johns Hopkins University. (IANS)
