Vaccinia neck tie, blue/grey

Vaccinia virus, a less dangerous relative of variola, forms the basis for the smallpox vaccine which was used to accomplish one of history's great public health achievements - global elimination of smallpox.  The IA design is dedicated to the courageous US led WHO team instrumental in this effort.  It features the two most typical appearances of the virus, brick and horseshoe shaped, and is highlighted by images of the bifurcated needle used in the vaccination process.
