Coronavirus plasma treatment still experimental: WHO
WHO’s Chief Scientist Dr Soumya Swaminathan during a press briefing said that so far, the results are not conclusive. At the moment, it is still very low-quality evidence.
Convalescent plasma is a century-old treatment that was used to fight off flu and measles outbreaks in the days before vaccines, and was tried more recently during the Ebola outbreak.
Dr Swaminathan said, WHO considered plasma therapy to be experimental and that it should continue to be evaluated. She said the treatment is difficult to standardize: Plasma must be collected individually and people produce different levels of antibodies.
