The Texas attorney general says it's "simply unacceptable" to charge exorbitant prices for flu shots at a time like this.

Greg Abbott spoke on N-B-C's "Today" show about the lawsuit he has filed against two flu shot distributors. The suit claims they hiked the price of the vaccine, which is in short supply because of manufacturing problems.

Abbott says the companies are trying to charge hospitals as much as a-thousand percent more for what he calls "essential medical supplies." Abbott says that's putting lives at risk.

The state will seek a refund of any money the hospitals were overcharged and various penalties.

One hospital bought the vaccine for about 400 dollars a vial, compared to the 70 dollars it typically pays. Each vial contains enough vaccine for ten shots.
