Flu Facts

Influenza (flu) is a serious contagious respiratory disease that infects the nose, throat, and lungs, and can lead to hospitalization and even death. It can be spread by coughing, sneezing, or nasal secretions. By getting the flu vaccine, you can protect yourself from influenza, and may also avoid spreading influenza to others.

What flu viruses does the vaccine protect against?
The Fluarix Quadrivalent vaccine is designed to protect against four influenza viruses that experts predict will be the most       common during the upcoming season. The 2018-2019 influenza vaccine is made from the following four viruses: A/Singapore/GP 1908/2015 (H1N1) IVR-180, (an A/Michigan/45/2015 (H1N1) pdm09-like virus), A/Singapore/INFIMH-16-0019/2016 (H3N2) NIB-104, B/Maryland/15/2016 NYMC BX-69A (a B/Colorado/06/2017-like virus), and B/Phuket/3073/2013.

Do I need to get vaccinated again this year?
Yes. Influenza viruses are always changing, so annual vaccination provides the best protection against influenza throughout flu season. Protection lasts about a year.

When should I get vaccinated?
CDC recommends that people get vaccinated against influenza as soon as 2018-2019 flu season vaccine becomes available in their community. It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against influenza.

Who should get a flu shot this year?
All people 6 months of age and older should get the flu vaccine. Vaccination is especially important for people at higher risk of severe influenza and their close contacts, including healthcare personnel and close contacts of children younger than 6 months.

Who should not be vaccinated against seasonal flu?
  • People who have a severe allergy to chicken eggs.
  • People who have had a severe reaction to an influenza vaccination.
  • People who developed Guillain-Barre syndrome.
  • Children younger than 6 months.
  • People who have a severe illness with a fever should wait until their symptoms lessen.
