Doctors recommend getting a flu shot each new flu season for a few reasons. One of the main reasons is that the flu virus tends to change every year. This means that the strains of the flu virus that circulate in one flu season may be different from those in the following season. Therefore, the flu shot from the previous flu season may not provide adequate protection against the new strains of the flu virus.
To keep up with these changes, scientists monitor the flu virus closely and develop new vaccines each year. These vaccines are designed to protect against the specific strains of the flu virus that are expected to circulate in the upcoming flu season. By getting a flu shot each year, individuals can ensure that they are protected against the latest strains of the flu virus.
It's important to note that the flu shot does not "wear out" over time or get eliminated by the body. However, the effectiveness of the vaccine can diminish over time as the circulating strains of the flu virus change. That's why it's recommended to get a new flu shot each year to maximize its effectiveness and keep up with the changing flu virus.
