The Mission of every Infectious Awareables tie is to generate interest, discussion - even excitement - about serious public health issues which affect us all. Believing that humor can be a powerful educational tool, Infectious Awareables neckties take an atypical, slightly irreverent approach to some very serious subjects. A portion of the proceeds from each tie is donated to organizations that are dedicated to research, education or treatment of these diseases. You can do your part to help educate people about these diseases by getting your tie Today. Vaccinia: Vaccinia virus is a less dangerous relative of variola and is the basis for smallpox immunization. Using the bifurcated needle shown here, a US led WHO team courageously administered vaccine worldwide, resulting in one of public health's great triumphs - global eradication of smallpox.
