An oculorespiratory syndrome, typically mild, has been linked to influenza vaccination, and it may or may not recur upon subsequent flu vaccinations; its pathogenesis is uncertain
The flu vaccine for the 2009-10 season will contain the same H3N2 and H1N1 (NOT the swine H1N1) antigens as were in the past year's vaccine, but will have a new influenza B component
Most flu last year was H1N1, and all tested H1N1 strains were resistant to Tamiflu, but sensitive to adamantanes. Tested H3N2 and Influenza B strains were sensitive to both Tamiflu and Zanamivir.
