Mexican authorities said they are studying the case of a 32-year-old female doctor who was hospitalised after receiving the Pfizer-BioNTech Covid-19 vaccine.

The doctor, whose name has not been released, was admitted to the intensive care unit of a public hospital in the northern state of Nuevo Leon after she experienced seizures, difficulty breathing and a skin rash, Reuters reported.

“The initial diagnosis is encephalomyelitis,” the health ministry said in a statement. Encephalomyelitis is an inflammation of the brain and spinal cord.

The ministry added that the doctor has a history of allergic reactions and said that there is no evidence from clinical trials that anyone has developed an inflammation of the brain after the vaccine’s application.
