MOSCOW (AP) _ A U.S. charitable group is paying for hundreds of children in Russia's Far East to receive hepatitis B and measles vaccinations, a news report said Monday.

The California chapter of The Rotary Club will give the government of the Primorye region $500,000 to purchase and administer the vaccines, the ITAR-Tass news agency reported.

The Rotary Club is also considering paying for medical treatment of 10 Primorye children who suffer from rare diseases that have affected their growth, the report said.

Russia has trouble providing even the most basic medical supplies because of the country's economic crisis. The collapse of the ruble last August worsened the situation by making imported medicines much more expensive.
