Parents lined up to get their children free vaccinations at 3 Houston area schools. It`s the 16th year that Congressman Gene Green has hosted the immunization day.

According to a study by Kids Count, Texas has the highest rate of uninsured children in the nation. So for many families, going to the doctor and paying for these types of shots is not a possibility.

This is also the cheapest way to help these kiddos avoid serious health problems later in life.  But none of that really matters to the kids getting needles jabbed into their arms.
