Merck recalls batch of MMR vaccine released early

NEW YORK (AP) — Merck & Co. said Thursday it is recalling 39,000 doses of a vaccine against measles, mumps and rubella because it was shipped before the company finished an internal approval process.

Merck said it accidentally shipped the batch of MMRII vaccine, but its quality, safety and effectiveness were confirmed before it went out. The company, based in Whitehouse Station, N.J., said it was recalling the batch as a precaution and already has asked customers to return the 39,000 vaccines.

Merck distributes about 10 million doses of MMRII in the U.S. every year. It said the recall shouldn't affect its ability to meet demand.

Shares of Merck rose 24 cents to close Thursday at $39.45 after touching a 52-week high of $39.79. They have traded as low as $29.47 the past year.
