On 8 May 1980, the World Health Organization officially announced that “smallpox eradication has been achieved throughout the world”. The upper cover of this report reproduces an electron micrograph of a specimen of variola virus taken from the last case of endemic smallpox in the world, 26 October 1977. This was the successful conclusion of worldwide vaccination efforts initiated by Jenner in 1798. See No. 5423.

The first list, published in 1977, included 204 pharmaceutical drugs.^[1] The WHO updates the list every two years. The WHO later added a separate WHO Model List of Essential Medicines for Children up to 12 years of age.

As of 2016, at least 156 countries have created national lists of essential medicines based on the WHO's model list.^[2] The national lists contain between 334 and 580 medications.^[3]
