Many believe that once they get the flu, they're immune for the rest of the winter. Unfortunately, that is not the case. You can get the flu twice, as 7-year-old J.J. Butson found out. The boy’s mom, Brandi, says his second bout with the flu was worse than the first. “He had a temperature of 104.6,” she told Inside Edition. “We rushed him to the doctor. I couldn't believe it because I thought you could only get the flu once.” He says he hopes he gets well for his upcoming birthday party.
