Plasma for Medicines

A donor is connected to an apheresis machine which separates plasma from blood as people donate blood plasma for medicines for the first time in more than 20 years at the Twickenham Donor Centre, south-west London, after a ban on the procedure was lifted in February. The ban was originally imposed in 1998 amid concerns about the spread of a human variant of BSE dubbed "mad cow disease" known as Creutzfeldt Jakob Disease. Picture date: Wednesday April 7, 2021.
