Seasonal Flu Vaccine
- Last Updated: 9.29.16
The national Centers for Disease Control and Prevention (CDC) recommends everyone 6 months of age and older get vaccinated against the flu. It is extremely important for some people to get vaccinated, especially people who are at high risk of developing serious complications like pneumonia if they get sick with the flu. This includes people who have certain medical conditions, e.g., asthma, diabetes or chronic lung disease; pregnant women; and those 65 years old and older. Household contacts and caregivers of people at high risk of developing serious complications should also get the flu vaccine.
A flu vaccine is needed annually, because flu viruses are constantly changing. The flu vaccine is formulated each year to keep up with the flu viruses as they change. Studies have shown that the body's immunity to influenza viruses (acquired either through natural infection or vaccination) declines over time.
Each year in the United States, on average 23,600 people die from seasonal flu-related complications and more than 200,000 people are hospitalized from seasonal flu-related causes. During flu season 2014-2015, the Department of Health provided more than 20,600 doses of seasonal flu vaccine at County clinics.
