With colder weather comes flu season. The Center for Disease Control (CDC) recommends a yearly flu vaccine as the first and most important step in protecting against this serious disease.
The CDC notes that some groups should especially get the flu vaccine because they are at higher risk for severe complications if they get the flu. This includes those who have chronic neurological disorders and those who are taking immune suppressant medications. The CDC recommends that these groups avoid the nasal spray vaccine because it is made with a live virus.
