What is Flublok Quadrivalent 2021-2022?
Influenza virus ("the flu") is a contagious disease caused by a virus that can spread from one person to another through the air or on surfaces. Flu symptoms include fever, chills, tiredness, aches, sore throat, cough, vomiting, and diarrhea. The flu can also cause sinus infections, ear infections, bronchitis, or serious complications such as pneumonia.
Influenza causes thousands of deaths each year, and hundreds of thousands of hospitalizations. Influenza is most dangerous in children, pregnant women, older adults, and people with weak immune systems or health problems such as diabetes, heart disease, or cancer.
Flublok Quadrivalent 2021-2022 is for use in adults and children at least 6 months old, to prevent infection caused by influenza virus. This vaccine helps your body develop immunity to the disease, but will not treat an active infection you already have.
Flublok Quadrivalent 2021-2022 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 2021-2022 (flu shot) is made from "killed viruses." This medicine is also available in a nasal spray form, which is a "live virus" vaccine. This medication guide addresses only the injectable form of this vaccine.
Like any vaccine, Flublok Quadrivalent 2021-2022 may not provide protection from disease in every person.
Warnings
Flublok Quadrivalent 2021-2022 is made from "killed viruses" and will not cause you to become ill with the flu virus.
