Dr. Barbara Ferrer says there were long lines at the clinics Saturday.

More free clinics are scheduled for Sunday and the upcoming week.

Ferrer announced the child’s death on Friday, but it hasn’t been confirmed whether the flu was the cause of death. Many parents say news of the child’s death prompted them to get their children vaccinated Saturday.

Boston has declared a public health emergency because of the flu. State health officials have reported about 6,000 confirmed flu cases in the state and 18 flu-related deaths, all in adults.
