(CNN)Plasma Technologies LLC has signed a defense contract worth $750,000 to develop scaled-up Covid-19 convalescent plasma technologies, according to an announcement on the Department of Defense website Monday.
Researchers hope this old-fashioned treatment will work for coronavirus
It's the latest development in the effort to use a 19th century treatment to help 21st century patients.
The contract with the DoD's Joint Acquisition Task Force is to develop a new convalescent blood plasma process that makes more serum-derived products, and faster.
President Donald Trump and US health leaders have done a full court press to encourage people who survived Covid-19 to donate plasma to help those who are sick.
Two weeks ago, on a tour of the Red Cross, Trump implored people to volunteer to donate plasma "as soon as you can."
"We have a lot of people that would heal, would get better. As soon as you can, please," Trump said.
While nearly 67,000 people have been infused with the treatment and nearly 14,000 physicians are using it, according to UScovidplasma.org, it's still not clear if it works. Several studies are under way.
Convalescent plasma is a treatment created out of blood from people who have recovered from an infection such as Covid-19. Plasma is the liquid portion of blood containing immune cells and antibodies -- proteins the body makes to fight infection. The plasma can be infused into a sick person to help recovery.
Since the Victorian era, doctors have used this treatment to fight severe cases of the flu. The treatment has also shown success with two other deadly coronaviruses - MERS and SARS. Yet it will take studies to prove that it works to treat Covid-19. Absent other treatments, doctors have opted to use the treatment as it was still being studied.
When the Covid-19 pandemic hit New York City hard in March, doctors desperate to save patients weren't sure what might help. Plasma from recovered Covid-19 patients showed some early promise. For professionals used to relying on scientific evidence and established facts, there was -- and still is -- little to work with.
