Poxviruses have long been a cause of fear as well as curiosity for humankind. One particularly infamous poxvirus, smallpox, alone may have killed more than 500 million people in the last century.
Smallpox didn’t discriminate between rich, poor, young, old, and killed a third of the individuals whom it infected. The turning point came with evidence of the efficacy of the smallpox vaccine. Thus followed a concerted effort worldwide to administer the vaccine and eventually eradicate the dread disease. This feat has stood as a testament to the power of sustained global public health initiatives.
