A Montgomery County father is upset, because his child was given the season flu vaccine by accident.

The flu mist vaccine was administered by workers from the Montgomery County Health Department. The health department takes care of day-to-day school health needs at Camargo Elementary School.

School officials say the health worker mistook seven-year-old Jacob Wages for another child with a similar name, and gave him the vaccine.

Wages' father Matthew Angel was he's upset, because he specifically denied permission for his son to receive the shot.

Montgomery County Health Department spokeswoman Pam Spradling says an investigation has been launched to see exactly how this sort of mix-up happened.
