And yes, according to the CDC, it is possible that one person in the OP's office got some form of H1N1 from a vaccinated (nasal spray) person and that this one recipient of the disease spread it to the office. It may be weaker than the original, but it still takes a few sick days and take an office down temporarily. And yes, it's better than everyone getting complications from pneumonia and dying, but even a weak version can spread and put people in bed.
