As we prepare to enter the yearly flu season, the American Public Health Association’s “Get Ready for Flu Day!” reminds us of the importance of preventing the flu, so we can protect ourselves and our community members this season.
What is the flu?
Influenza (more commonly known as the flu) is an upper respiratory infection caused by the influenza virus. The illness can be mild or severe, but is typically characterized by a fever, cough, sore throat, runny nose, muscle aches, headaches, and/or fatigue. When an infected individual coughs, sneezes, or talks, small droplets containing the virus can travel into another person’s mouth or nose, infecting them.
What is the flu vaccine, and when should I get it?
The most important and effective preventive method against this infection is the flu vaccine, typically created with inactivated influenza viruses. A new flu vaccine is created every year to account for the fact that the virus is constantly changing. Therefore, it is always necessary to get the latest flu shot to be protected each season.
With a few exceptions, everyone should get a seasonal flu vaccine. While it’s better to get the vaccine as early as possible (September to October), you should still get vaccinated even if you miss this timeframe, as the flu remains in circulation throughout the winter. After receiving the vaccine, some people may experience mild side effects. However, these are completely safe and normal, and will usually go away within a few days.
Why is getting vaccinated for the flu important?
The flu vaccine offers protection from the influenza virus. And while it’s still possible to contract the flu after vaccination, the flu vaccine has other benefits. Research has shown that the vaccine can reduce the severity of the illness if you get infected, can reduce the potential for flu-related hospitalization, and can help protect those around you, particularly those with certain chronic illnesses. When the vaccine is made up of viruses that closely match those in circulation, evidence has shown that the flu vaccine will reduce the risk of having to go to the doctor by 40 to 60%.
For adolescents in particular, the vaccine provides an important safeguard against missing school and important events during the school year. It ensures that adolescents are still able to work and socialize with little concern for contracting the flu. Most importantly, receiving the flu vaccine helps to protect other vulnerable family and community members from getting sick and potentially experiencing serious complications.
Most adolescents can get their flu shot at their healthcare provider’s office or at a local pharmacy, free of charge or at a low cost. Be sure to get your vaccine today to get ready for the flu!
