At what age can adults get the flu vaccine?

Adult influenza vaccine is recommended for all adults aged ≥18 years, especially pregnant women, the elderly, medical staff and those with chronic diseases and other high-risk groups should be given priority. Influenza vaccine is the most effective way to prevent influenza, and the appropriate vaccine type should be selected according to personal health status.

1Why should you get a flu shot?

Influenza is an acute respiratory infectious disease caused by influenza virus, which can cause symptoms such as high fever, cough, and general fatigue. In severe cases, it may cause pneumonia and even endanger life. For adults over 18 years old, influenza vaccination can not only reduce the risk of influenza infection, but also effectively alleviate the severity of symptoms after infection. For special groups such as the elderly, pregnant women, and patients with chronic diseases, influenza can cause more serious complications, and vaccine protection is particularly necessary.

2 Types of influenza vaccines suitable for different groups of people

There are two main forms of influenza vaccines: inactivated vaccine IIV and live attenuated vaccine LAIV. Adults usually choose inactivated vaccines, especially those with low immunity or chronic diseases, while healthy adults aged 18-49 can also choose live attenuated vaccines. Pregnant women and the elderly should choose inactivated vaccines that have been clinically proven to be safe and inactive.

3 Things to note when getting a flu vaccine

When you are vaccinated, you need to make sure that you have no acute illness symptoms such as fever. You need to observe for 10-15 minutes after the injection to prevent allergic reactions. People with protein allergies such as egg allergies should choose approved egg-free vaccines. Within seven days after vaccination, you may experience mild discomfort, such as pain at the injection site and low-grade fever. These are normal reactions and usually do not require special treatment.

For adults aged 18 and above, the flu vaccine is an effective basic health care method to prevent the flu, and it is especially recommended for high-risk groups to get vaccinated every year. Remember to get vaccinated before the peak flu season in autumn and winter each year to provide more comprehensive health protection for yourself and your family.
