 [ Symptoms ] will flu symptoms be less severe after getting a flu vacciene even though the strain that broke out was not covered  it seems rampant in south texas my entire family got the flu vaccine late 2012 and despite that my youngest got the flu i understand that the vaccine only covers up to 3 strains and that the strain that broke out was not included  i am just curious then if the vaccine affords us any coverage at all thank you  philip [ Disease ] maybe many flu strains are genetically close so past infections past flu vaccines and even this year is strain may still offer some protection this year is flu vaccine is considered to be a good match not true in all previous years vaccine so there has been very good protection against the true lab confirmed cases of influenza
