Eradication History
About Eradication History
Two diseases have been eradicated through vaccination. Smallpox was declared eradicated in 1980 after a global campaign led by DA Henderson. The last natural case occurred in Somalia in 1977. Rinderpest, a cattle disease, was declared eradicated in 2011. Polio is on the verge of eradication. Wild poliovirus remains endemic only in Pakistan and Afghanistan, with annual case numbers fluctuating. The Global Polio Eradication Initiative, launched in 1988, has invested billions of dollars. Challenges include conflict, vaccine hesitancy, and vaccine derived poliovirus. Measles elimination has been achieved in some regions but not globally. Rubella elimination is linked to measles efforts. The WHO has identified malaria, lymphatic filariasis, and guinea worm as potentially eradicable diseases. Disease eradication remains a long term goal for a small number of vaccine preventable diseases.
