What is Flublok Quadrivalent?
Influenza virus (commonly known as "the flu") is a serious disease caused by a virus. Influenza virus can spread from one person to another through small droplets of saliva that are expelled into the air when an infected person coughs or sneezes. The virus can also be passed through contact with objects the infected person has touched, such as a door handle or other surfaces.
Flublok Quadrivalent is used to prevent infection caused by influenza virus. The vaccine is redeveloped each year to contain specific strains of inactivated (killed) flu virus that are recommended by public health officials for that year.
The injectable Flublok Quadrivalent (flu shot) is a "killed virus" vaccine.
Flublok Quadrivalent works by exposing you to a small dose of the virus, which helps your body to develop immunity to the disease. This medicine will not treat an active infection that has already developed in the body.
Flublok Quadrivalent is for use in adults who are at least 18 years of age.
Becoming infected with influenza is much more dangerous to your health than receiving this vaccine. Influenza causes thousands of deaths each year, and hundreds of thousands of hospitalizations. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.
Like any vaccine, Flublok Quadrivalent may not provide protection from disease in every person. This vaccine will not prevent illness caused by avian flu ("bird flu").
