Annually all persons over 6 months of age should receive the annual seasonal flu vaccination. While the Center for Disease Control (CDC) recommends that the flu vaccine should be received shortly after it becomes available, if possible in October, vaccination should and does continue throughout the flu season. Each year the Flu Season varies, starting as early as November and often continues into April with the peak being January and February. Therefore, vaccination in December and even January can be timely. Typically, it takes two weeks for the vaccine to provide protection so getting the vaccine yearly as soon as possible is beneficial.
