None of the approved influenza A 2009 (H1N1) monovalent vaccines or seasonal influenza vaccines contains adjuvants ( 1-- 5 ). (cdc.gov)
CDC's Advisory Committee on Immunization Practices has made recommendations previously for which persons should be the initial targets for immunization with influenza A (H1N1) 2009 monovalent vaccines and has issued guidelines on decisions for expansion of vaccination efforts to other population groups ( 6 ).

Influenza vaccination practice, which is based on neutralizing antibodies, requires being able to predict which viral strains will be circulating. (cdc.gov)
The 1997 outbreak of H5N1 avian influenza in humans in Hong Kong ( 1 , 2 ) caused alarm because it involved highly pathogenic strains of an influenza subtype to which humans lack immunity. (cdc.gov)
Neutralizing antibodies are specific to subtype and often strain, so vaccination based on eliciting such antibodies requires accurate prediction of the viral strains that will circulate during the influenza season and leaves little time for vaccine preparation. (cdc.gov)
Even with usual epidemic strains, difficulties and delays in the production of an adequate vaccine supply have occurred in some years (3) . (cdc.gov)
Vaccines using conserved components of influenza A virus can induce protection against many influenza A strains, including those of divergent subtypes. (cdc.gov)
However, there may be sufficient antigenic variation (antigenic drift) within the same subtype over time, so that infection or vaccination with one strain may not induce immunity to distantly related strains of the same subtype. (cdc.gov)
As a consequence, the antigenic characteristics of current strains provide the basis for selecting virus strains to be included in the vaccine. (cdc.gov)
The viruses implicated as the major cause of nationwide epidemic activity were influenza A(H3N2) strains, and in particular, these H3N2 viruses were shown to cause nearly all outbreaks in nursing home or hospital settings for which laboratory diagnosis was obtained. (cdc.gov)
Almost 80% of influenza virus isolates reported in the United States were type A(H3N2) strains, mostly similar to A/Bangkok/79(H3N2), a strain included in the vaccine for the last 3 years. (cdc.gov)
A study led by St. Jude Children's Research Hospital scientists highlights a new approach for developing a universal influenza vaccine that could protect against multiple flu strains, including deadly pandemic strains. (stjude.org)

The effectiveness of the flu vaccine, as well as the strains it covers, varies year to year depending on - among other things - how well researchers are able to predict which strains will be the most virulent each season. (snopes.com)
The effectiveness of the vaccine does vary each year, since the predominant circulating influenza strains vary from year to year, affecting the intensity and severity of the influenza season as well as vaccine effectiveness. (nfid.org)

Excess deaths in this period were attributable mainly to influenza A viruses, although influenza B epidemics were occasionally associated with excess deaths, as in 1979-1980. (cdc.gov)
Influenza A viruses are classified into subtypes on the basis of two antigens: hemagglutinin (H) and neuraminidase (N). Three subtypes of hemagglutinin (H1, H2, H3) and two subtypes of neuraminidase (N1, N2) are recognized among influenza A viruses that have caused wide-spread human disease. (cdc.gov)
Although influenza B viruses have shown much more antigenic stability than influenza A viruses, antigenic variation does occur. (cdc.gov)
Influenza B viruses were isolated infrequently early in the season, although their prevalence increased toward the end of the season, including outbreaks in several schools and nursing homes in April and May. (cdc.gov)
