"Using vaccination and other disease control measures, we have eliminated two virus infections that have, through the ages, caused massive economic damage and loss of life: human smallpox (1980) and bovine rinderpest (2011).
Another scourge, polio, is close to eradication. But problems remain with vaccine coverage (and the safety of the medical teams) in regions that are essentially war zones.
We could also eradicate measles, but this is hampered by some parents in the developed world who believe they do not have a responsibility to immunise their children against the standard infections of childhood.
The rinderpest eradication shows it’s easier to eradicate viruses in domestic animals than people!"
