("=Wyeth: Rwanda Using Prevenar In Immunization Program," published at 3:07 p.m. EDT, incorrectly described Wyeth's vaccine Prevenar in the fourth paragraph. The correct version follows:)

The Rwandan government will launch the first national immunization program against pneumococcal disease in a developing country Thursday.

The African country plans to administer Wyeth Inc.'s (WYE) vaccine Prevenar to nearly all Rwandan children less than a year old by the end of 2009, and to all Rwandan infants on a routine basis after that.

Prevenar is included in the national immunization programs of 35 high- and middle-income countries, including 25 in Europe, the Middle East and Africa.

Prevenar is the European version of Wyeth's blockbuster U.S. vaccine Prevnar. Pneumococcal disease, which can cause such potentially life-threatening illnesses as pneumonia, meningitis and sepsis, is the leading vaccine-preventable killer of children younger than 5 worldwide.

Wyeth donated more than three million doses of Prevenar to Rwanda and the Gambia through the GAVI Alliance, a partnership that includes the World Health Organisation, UNICEF and the World Bank and is funded by donor countries and the Bill and Melinda Gates Foundation.

"If fully rolled out in GAVI countries, the pneumococcal vaccine could save the lives of more than 440,000 children by 2015," said GAVI Chief Executive Dr. Julian Lob-Levyt.

The U.S. Agency for International Development and WHO are helping the Rwandan Ministry of Health administer the program.

Wyeth's shares recently traded at $42.18, down 0.9%. Pfizer Inc. (PFE), the world's largest pharmaceutical company, has agreed to acquire Wyeth in a deal intially valued at $68 billion.
