Guillain-Barre syndrome (GBS) is a rare disorder involving an individualís immune system attacking his/her nerves. It may be triggered by a severe bacterial or viral infection. The initial symptoms of weakness and tingling of feet and legs sometimes lead to the paralysis of the upper body.
Two independent reports from India and the United Kingdom found that the Covishield may trigger symptoms associated with the GBS in a small percentage of the vaccinated individuals. It was found that few people have experienced facial weakness upon receiving the jabs. These researches emphasised that the benefits of these vaccines far outweigh these adverse implications.
