The flu vaccine is designed to protect against the strains of flu virus that research indicates will be most common during the upcoming season. If Bobby got sick with a different strain of the flu than the ones included in the vaccine, the vaccine would not be effective in preventing that illness. This is a common issue with flu vaccines due to the high mutation rate of the flu virus.
