A high-dose vaccine (Fluzone High-Dose) four times the strength of standard flu vaccine was approved by the FDA in 2009. [22] [23] [24] This vaccine is intended for people 65 and over, who typically have weakened immune response due to normal aging. The vaccine produces a greater immune response than standard vaccine.
During the worldwide Spanish flu pandemic of 1918, "Pharmacists tried everything they knew, everything they had ever heard of, from the ancient art of bleeding patients, to administering oxygen, to developing new vaccines and serums (chiefly against what we call Hemophilus influenzae – a name derived from the fact that it was originally considered the etiological agent – and several types ...
Centers for Disease Control and Prevention as Dr. Terrence Tumpey examines a reconstructed version of the 1918 flu. In 1995, Jeffery Taubenberger of the US Armed Forces Institute of Pathology (AFIP), wondered if it might be possible to recover the virus of 1918 flu pandemic from the dried and fixed tissue of victims. He and his colleagues ...
Dr Terrence Tumpey examines a reconstructed version of the Spanish flu virus at the CDC. An effort to recreate the Spanish flu strain (a strain of influenza A subtype H1N1) was a collaboration among the Armed Forces Institute of Pathology, the USDA ARS Southeast Poultry Research Laboratory, and Mount Sinai School of Medicine in New York

In general, influenza vaccines are only effective if there is an antigenic match between vaccine strains and circulating strains. [10] [2] Most commercially available flu vaccines are manufactured by propagation of influenza viruses in embryonated chicken eggs, taking 6–8 months. [2]
When the Spanish flu, the history's deadliest known influenza pandemic, began in 1918, most scientists believed that Pfeiffer's bacillus caused influenza. With the lethality of this outbreak (which killed an estimated 20 to 100 million worldwide) came urgency—researchers around the world began to search for Pfeiffer's bacillus in patients ...
