KIEV, June 1 - Another criminal case may be opened against former Prime Minister Yulia Tymoshenko, in connection with the purchase of vaccines during the flu epidemic in November 2009, announced Renat Kuzmin, the first deputy prosecutor general.

"The investigation into a criminal case involving schemes in the Health Ministry has been completed. If the investigator gets materials from the U.S. court in Oregon or other official materials on this matter, the criminal case against Tymoshenko related to ambulance vehicles and other abuse in the Health Ministry may be resumed. If there are enough grounds, another criminal case may be opened," Kuzmin said in the Ukrainian parliament on Wednesday.
