CONNECTICUT - Pediatricians are frustrated some parents still haven't been able to get their children vaccinated against the flu.

Doctors say flu shot shipments are arriving sporadically, and many local pharmacies and doctors' offices were waiting Friday for their next shipments. 

The state health department is running distribution of shots for children under 18 years old, meaning doctors don't have as much control over how much vaccine they get and when.

The state Health Department says the flu vaccine supply is still strong and shipments of vaccine are going out daily as orders come in from doctors and pharmacists.
