Lehigh Valley Health Network is giving new meaning to the term "drive-thru."

Long lines of cars pulled up at Coca-Cola Park Sunday for a free "drive-thru" flu shot clinic.

This was the second day of free flu shots.

On Saturday, LVH gave out free vaccines at Dorney Park.

LVH officials said they estimate they administered around 10,000 free flu shots at the two-day clinic.
