The flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. Some people, such as older people, young children, and people with certain health conditions, are at high-risk for serious flu complications.

The seasonal flu vaccine protects against the infuenza viruses that research indicates will be most common during the upcoming season. Traditional flu vaccines (called "trivalent" vaccines) are made to protect against three flu viruses; an influenza A (H1N1) virus, an influenza A (H3N2) virus, and an influenza B virus. There are also flu vaccines made to protect against four flu viruses (called "quadrivalent" vaccines). These vaccines protect against the same viruses as the trivalent vaccine and an additional B virus.

The best way to prevent the flu is by getting a flu vaccination each year. Traditional flu shots are manufactured based on influenza viruses that research indicates will be most common during the season. 

For the 2017-2018 season, CDC recommends use of flu shot (inactivated influenza vaccine or IIV) and the recombinant influenza vaccine (RIV). The nasal spray flu vaccine (live attenuated influenza vaccine or LAIV) should not be used during 2017-2018. The 2017-2018 influenza vaccination recommendations are now available.

Recommendations for flu vaccination of persons with egg allergy have been modified for the 2017-2018 season. CDC recommends:

  • Persons with a history of egg allergy who have experienced only hives after exposure to egg should receive flu vaccine. Any licensed and reccomended flu vaccine (i.e.,and form of IIV or RIV) that is otherwise appropriate for the recipient's age and health status may be used.
  • Persons who report having had reactions to egg involving symptoms other than hives, such as angioedema, respiratory distress, lightheadedness, or recurrent emesis; or who required epinephrine or another emergency medical intervention, may similarly receive any licensed and recommended flu vaccine (i.e, any form of IIV or RIV) that is otherwise appropriate for the recipient's age and health status. The selected vaccine should be administered in an inpatient or outpatient medical setting (including,but not necessarily limited to hospitals, clinics, health departments, and physician offices). Vaccine administration should be supervised by a health care provider who is able to recognize and manage severe allergic conditions.
  • A previous severe allergic reaction to flu vaccine, reardless of the component suspected of being responsible for the reaction, is a contraindiction to future reciept of the vaccine.
