Do flu shots work?
Not in babies.. "no evidence that injecting children 6-24 months of age with a flu shotwas any more effective than placebo..
Not in children with asthma.....children who get the flu vaccine are more at risk for hospitalization than children who do not get the vaccine." Reference: The American Thoracic Society’s 105th International Conference, May 15-20, 2009, San Diego.
Not in adults.....Vaccination of healthy adults only reduced risk of influenza by 6%
Not in the Elderly.......In a review of 64 studies in 98 flu seasons, For elderly living in nursing homes, flu shots were non-significant for preventing the flu. For elderly living in the community, vaccines were not (significantly) effective against influenza, ILI or pneumonia
