Infectious disease eradication is a major public health achievement. Smallpox is the only human infectious disease that has been eliminated by deliberate intervention, and this was accomplished using strategic global immunization efforts. The public generally understands that effective vaccination is a key component of infectious disease prevention and eradication; for example, there has been substantial recent public interest in vaccination for emerging global health threats such as avian influenza, Ebola, and Zika virus.
