Safety Alerts & Recalls

What does this mean?

Influenza or "the flu" is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. Because the influenza viruses that causes people to get sick can change, each year's vaccine may be different from the previous year. Therefore, it is important to get the flu vaccine every year.

The vaccines available to protect against influenza have been approved by the FDA based on a review of the vaccines' safety and effectiveness. If you have any questions about the 2010-2011 seasonal flu vaccine, please follow up with your doctor or other primary healthcare provider.

2010-2011 Flu Vaccine: What Consumers Should Know

The FDA has published a web page titled "2010-2011 Influenza Season Vaccine Questions and Answers." The 2010-2011 seasonal influenza vaccine (also called "flu vaccine") includes three strains: an A (H1N1) that is the same strain that is the cause of the pandemic that began in 2009 (also known as swine flu), an A (H3N2) that is different than last year's seasonal vaccine and a B strain that is the same as last year's formulation.

This year, two different vaccines are not needed, only one. During last year's flu season, two different vaccines were needed; one to prevent seasonal flu and another to prevent flu that is the cause of the 2009 (H1N1) pandemic.

Several flu vaccines made by different manufacturers are available and each vaccine is approved for use in specific age groups and patient populations. The warning and precautions section for Afluria, one of the flu vaccines, has been updated to warn about a possible increase in incidence of fever and febrile seizure among young children, mainly among those less than 5 years of age. The FDA Question and Answer guide provides a summary of additional key facts and answers some common questions about Afluria and the other available influenza vaccines.
