What is the difference between Flublok and Flublok Quadrivalent?

Official Answer by Drugs.com 6 days ago

Flublok (influenza vaccine, recombinant hemagglutinin), a trivalent influenza vaccine, was originally approved for immunization against seasonal influenza in adults 18 years of age and older.

The FDA has also approved a quadrivalent formulation of Flublok for adults, too.

Flublok Quadrivalent protects against four influenza strains instead of just three, and is the first high antigen content quadrivalent vaccine with triple the active ingredient.

High antigen content flu vaccines may offer an advantage to people at high risk, such as seniors or those with lowered immunity.

Flublok Quadrivalent has the same purity advantages as trivalent Flublok, containing pure protein made without infectious influenza virus, antibiotics, eggs, thimerosal, preservatives, gelatin or latex.
