Hartford, Conn. (AP) - Connecticut public health officials say a manufacturer is recalling its H1N1 vaccine because of a lack of potency.
The Department of Public Health cites information from the federal Centers for Disease Control and Prevention that says manufacturer Sanofi Pasteur Inc. is recalling the vaccine.
State officials say Connecticut received 11,360 doses and more than 72 providers are affected. Health officials say safety is not an issue.
Representatives of the CDC and Sanofi Pasteur did not immediately return calls seeking comment.
The CDC says in a health update that Sanofi Pasteur found that the potency dropped below a pre-specified limit. Federal health officials say the small decrease in antigen content is unlikely to result in a "clinically significant" reduction in immune response and revaccinations are not necessary.
