Oxford vaccine faces setback

(1) One participant in Oxford vaccine trial developed symptoms of "transverse myelitis, a rare neurological disease caused by inflammation of the spinal cord". They are pausing the trial to determine if this is caused by the vaccine or not. (2) Previously, a participant in the Oxford vaccine trial developed multiple sclerosis. At the time, it was concluded to be unrelated to the vaccine. (3) If the complications are deemed to be a result of the Oxford vaccine, it will likely be shelved (4) Many of the coronavirus candidate vaccines use new techniques that have not been used before (5) China is pursuing an "inactivated-virus" vaccine, which is an older and more established technique (6) Some vaccines are released even though they have rare, severe side effects, for example a rotavirus vaccine that is still being used
