*This update provides new information regarding vaccination guidelines for 2009 H1N1 flu and seasonal flu for persons with chronic cardiovascular diseases.
The 2009-2010 flu season is upon us and many people are likely to get ill with either the usual seasonal flu or 2009 H1N1 flu. People with heart disease, cardiovascular disease, or who have had a stroke are at increased risk of having medical complications of flu. The information in this document is intended to help this group prevent getting seasonal and 2009 H1N1 flu and provide guidance if they develop flu-like symptoms.
Influenza Vaccine Guidance for Adults
If you have a history of heart disease, stroke, or other cardiovascular diseases, then you are at increased risk of serious flu-related complications and should be vaccinated with the seasonal flu shot as well as the 2009 H1N1 flu shot this season. Supplies of the vaccine against 2009 H1N1 are ample, and CDC is now encouraging everyone to get vaccinated, including people 65 years and older.
