Don’t wait to vaccinate
Getting an annual flu vaccine is the single best way to protect yourself and your family from flu and flu-related complications such as pneumonia, bronchitis, or worsening of chronic health conditions, such as heart disease, asthma, or diabetes. It can take up to two weeks for the vaccine to provide full protection. Since flu season could begin in October and last into May, it’s best to get vaccinated now. People who are at increased risk of developing serious complications from flu should definitely get a flu vaccine; as should their caregivers.
Limit the spread of illness
In addition to getting vaccinated, encourage family members to take these common sense measures to protect against flu.
Practice the three C’s to stay healthy and prevent germs from spreading at home, work and school:

- Cover: cover your cough and sneeze
- Contain: contain your germs by staying home
