Actress Anne Hathaway is spending her summer (06) vaccinating children in South America against Hepatitis A after her boyfriend set up a health foundation. The Brokeback Mountain star and Italian boyfriend RAFFAELLO FOLLIERI have been travelling through Central America giving kids a medical boost in Honduras and Nicaragua, among other places. She tells Hollywood trade paper Daily Variety, "I'm in love with the founder (of the Follieri Foundation), so I'd be going anyway. But I was glad I could use any presence I have to help the foundation. "Children are so vulnerable, especially in the Third World, where the cards are so stacked against them."
