However, a study involving 464 adults with average signs of the an infection final 12 months means that the Convalescent Plasma Therapy (CPT) has proven a limited effect in lowering the development to extreme illness or demise.
The study ‘Convalescent Plasma in the management of moderate COVID-19 in adults in India: open label phase II multicentre randomised controlled trial (PLACID trial)’ was performed in 39 private and non-private hospitals in India, involving 464 adults admitted between April and July final 12 months.
Tirupati connection
Of the practically 100 co-authors of the study report, 5 have been from the Tirupati-based Sri Venkateswara Institute of Medical Sciences (SVIMS), together with its Director and professor of neurology B.
