Fluzone, Fluzone High-Dose, and Fluzone Intradermal are all injectable influenza vaccines, made up of the 3 flu strains most likely to cause illness for that particular flu season, to protect people from influenza.

Fluzone High-Dose vaccines contain 4 times the amount of antigen (the part of the vaccine that prompts the body to make antibody) contained in regular flu shots. The additional antigen is intended to create a stronger immune response (more antibody) in the person getting the vaccine.

Fluzone Intradermal was licensed by the FDA for use in the United States for the 2011-2012 flu season. The intradermal flu vaccine is a shot that is injected into the skin instead of the muscle. The intradermal shot uses a much smaller needle than the regular flu shot, and it requires less antigen to be as effective as the regular flu shot. It is recommended for adults 18-64 years of age.
