Seasonal Influenza (Flu)

Influenza is a serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently. Even healthy people can get very sick from the flu and spread it to others.

The “seasonal flu season” in the United States can begin as early as October and last as late as May. During this time, flu viruses are circulating in the population.

An annual seasonal flu vaccine (either the flu shot or the nasal-spray flu vaccine) is the best way to reduce the chances that you will get seasonal flu and lessen the chance that you will spread it to others. When more people get vaccinated against the flu, less flu can spread through that community.

Almost everyone who is at least 6 months of age should get a flu vaccine this season. It’s especially important for some people to get vaccinated. Those people include the following:

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 including asthma, diabetes, and chronic lung disease.
• Pregnant women.
• People 65 years and older.
• People younger than 5 years (and especially those younger than 2).

People who live with or care for others who are high risk of developing serious complications. This includes:

• Household contacts and caregivers of people with certain medical conditions including asthma, diabetes, and chronic lung disease.
• Household contacts and caregivers of infants less than 6 months old.
• Health care personnel.

Who Should Not Be Vaccinated

• Influenza vaccine is not approved for children younger than 6 months of age.
• People who have had a severe allergic reaction to influenza vaccine should generally not be vaccinated.

 There are some people who should not get a flu vaccine without first consulting a physician. These include:

• People who have a moderate-to-severe illness with or without a fever (they should wait until they recover to get vaccinated).
• People who developed Guillain-Barré syndrome (GBS) within 6 weeks of getting an influenza vaccine.

Vaccines aren't just for kids

Vaccines aren't just for kids. In fact, the Centers for Disease Control and Prevention (CDC) report that many adults become ill, are disabled, or die each year from diseases that could easily have been prevented by vaccines.

Everyone from young adults to senior citizens can benefit from immunizations. The CDC has a short, online questionnaire that can help you find out if there are vaccines that are recommended for you.

Some of these diseases can be especially serious for adults age 65 and older:

- Influenza (flu)
- Shingles
- Diphtheria
- Pneumococcus (pneumonia)
- Tetanus
- Hepatitis A & B
