Professor Terry Nolan from the University of Melbourne, said it was entirely plausible the volunteer had suffered transverse myelitis (TM) as a direct result of the vaccine.

The exact cause of TM is unknown, but it has been reported to occur after infections and vaccinations. Shenzhen Kangtai Biological Products, based in the city of Shenzhen, will increase capacity to 200m per year by the end of 2021.
