Dear Dr. Dekleva,
We have approved your request to supplement your biologics license application for Measles, Mumps, Rubella and Varicella Virus Vaccine Live (ProQuad®), to include revisions to the package insert.
The Adverse Reactions section of the label has been revised to include two adverse events, encephalitis and epididymitis, to reflect updated data from post-marketing surveillance reports. Information regarding the potential risk of febrile seizures following ProQuad® administration has also been added to this section.
Please provide a PDF-format electronic version of all final printed labeling and implementation information at the time of use.
We will include information contained in the above-referenced supplement in your Biologics License Application File.
