Experts suspect that H1N1 flu vaccine might have resulted in acute disseminated encephalomyelitis (ADEM) in a thirteen-year-old boy in Guangzhou, South China's Guangdong province, Guangzhou Daily reported today.

A source from the city's health bureau said the local government will compensate the boy financially once he was diagnosed with the abnormal reaction from the H1N1 vaccine.

The boy was reportedly sent to the hospital on December 21st last year for running a fever and was discharged on January 21, 2010. He was inoculated the H1N1 vaccine on December 16, 2009.
