WASHINGTON, Oct. 20 (UPI) -- The Food and Drug Administration Monday dismissed as false rumors a "contaminated" lot of flu vaccine has been recalled.
"This is false. No contamination of any flu vaccine has been identified anywhere in the U.S. and the FDA has not recalled any lot of flu vaccine," the agency said.
At the same time, the agency said it and the Centers for Disease Control and Prevention are jointly investigating several recent reports of possible significant allergic reactions to flu vaccine.
"As with any vaccine, flu vaccine is capable of causing some side effects. These are very rarely severe. Most side effects from flu vaccine are mild such as arm soreness, redness or swelling where the shot was given, fever or achiness. More serious reactions to the flu vaccine do occur, but they are rare," it said.
The agency said the reactions reported do not suggest any problem with the flu vaccine at this time. It reminded that not all the reactions may have been caused by the vaccine.
