The person reportedly enrolled in a Phase 2/3 trial in the UK and had transverse myelitis—inflammation of the spinal cord that can be sparked by viral infections. The timing of this diagnosis, and whether it was directly linked to the vaccine, is unclear.

This vaccine uses a chimpanzee adenovirus to deliver #coronavirus genes into human cells. Adenovirus is typically harmless, but can sometimes trigger immune responses, which can harm the patient without generating the intended form of protection from the #coronavirus genes.
Too early to know if this suspected unexpected serious adverse reaction—SUSAR—is related to the #coronavirus vaccine. No more participants will be enrolled into the study until a full investigation is complete.
Studies of other #COVID19 vaccines will be reviewed for this SUSAR.
