Family Practice and Internal Medicine Physicians, Pediatricians, Rheumatologists, Pulmonologists, and Obstetricians are among the many Medical Practitioners that administer Influenza Vaccine to their patients each year to protect them against current viral strains. It is recommended that anyone six months and older, especially the elderly, be vaccinated since seasonal influenza associated-illness claims the lives of 3,000 to 49,000 Americans each year. The CDC has approved the following brands and strengths of Influenza Vaccine. Fluviron, Fluzone High-Dose, and Afluria are available in a Trivalent formula. Fluzone, Fluzone Pediatric, and Flulaval are available in both a Trivalent and Quadrivalent formula. Flumist has an intranasal delivery system and is only available in a Quadrivalent formula. Flu vaccines are usually given in the fall of each year.
