Safety Alerts & Recalls
What does this mean?
There are no safety concerns with these recalled lots of H1N1 vaccine. Rather, the recall is intended to notify any healthcare providers who may still have some of the recalled vaccine in their refrigerators. If you or your child has already received a nasal spray vaccine, the FDA has indicated that there is no need to re-administer the dose. Most of the doses were given out in October and November, when the vaccine was still at full potency.
If you have any questions about this recall or about the H1N1 influenza vaccine, please follow up with your doctor or other primary healthcare provider.
Voluntary Recall of 4.7 million Doses of Medimmune H1N1 Nasal Spray Vaccine
Medimmune is voluntarily recalling 4.7 million doses of the H1N1 Nasal Spray Vaccine given to prevent H1N1 influenza (often called "swine flu") because of a slight decrease in their potency that was detected during regular checks.
The recall involves H1N1 nasal spray vaccine doses with an expiration date of between Jan. 19 and Jan. 26, 2010. These vaccines were within potency specifications at the time of distribution. The cause of the loss of potency is still under investigation.
