Why should people get vaccinated against the 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. Over a period of 31 seasons between 1976 and 2007, estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of about 49,000 people. During a regular flu season, about 90 percent of deaths occur in people 65 years and older. 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 spread it to others. When more people get vaccinated against the flu, less flu can spread through that community.

CDC urges you to take the following actions to protect yourself and others from influenza (the flu):

Step One

Take time to get a flu vaccine.

• CDC recommends a yearly flu vaccine as the first and most important step in protecting against flu viruses.
• While there are many different flu viruses, a flu vaccine protects against the three viruses that research suggests will be most common. (See upcoming season’s Vaccine Virus Selection for this season’s vaccine composition.)
• Everyone 6 months of age and older should get a flu vaccine as soon as the current season’s vaccines are available.
• Vaccination of high risk persons is especially important to decrease their risk of severe flu illness.
• People at high risk of serious flu complications include young children, pregnant women, people with chronic health conditions like 哮喘, diabetes or heart and lung disease and people 65 years and older.
• Vaccination also is important for health care workers, and other people who live with or care for high risk people to keep from spreading flu to high risk people.
• Children younger than 6 months are at high risk of serious flu illness, but are too young to be vaccinated. People who care for them should be vaccinated instead.

Step Two

Take everyday preventive actions to stop the spread of germs.

• Try to avoid close contact with sick people.
• If you are sick with flu-like illness, CDC recommends that you stay home for at least 24 hours after your fever is gone except to get medical care or for other necessities. (Your fever should be gone without the use of a fever-reducing medicine.)
• While sick, limit contact with others as much as possible to keep from infecting them.
• Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
• Wash your hands often with soap and water. If soap and water are not available, use an alcohol-based hand rub.
• Avoid touching your eyes, nose and mouth. Germs spread this way.
• Clean and disinfect surfaces and objects that may be contaminated with germs like the flu.

Step Three

Take flu antiviral drugs if your doctor prescribes them.

• If you get the flu, antiviral drugs can treat your illness.
• Antiviral drugs are different from antibiotics. They are prescription medicines (pills, liquid or an inhaled powder) and are not available over-the-counter.
• Antiviral drugs can make illness milder and shorten the time you are sick. They may also prevent serious flu complications. For people with high risk factors, treatment with an antiviral drug can mean the difference between having a milder illness versus a very serious illness that could result in a hospital stay.
• Studies show that flu antiviral drugs work best for treatment when they are started within 2 days of getting sick, but starting them later can still be helpful, especially if the sick person has a high-risk health or is very sick from the flu. Follow your doctor’s instructions for taking this drug.
• Flu-like symptoms include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people also may have vomiting and diarrhea. People may be infected with the flu, and have respiratory symptoms without a fever.
