We continue to maintain strict product quality standards and multiple supply chain safeguards to ensure the safety and supply of our products, whether our medicines and vaccines are manufactured internally or externally.

Merck remains committed to the development and commercialization of vaccines and to reestablishing ourselves as a reliable global supplier of quality vaccines.

Restoring and ensuring supply of our products is a critical priority for Merck. The integration process is inherently complex, and while periodic supply interruptions may continue to occur as we complete the process, we expect resolution of most manufacturing and supply issues in 2011.
