Monkeypox is a virus, similar to smallpox but milder. It is infectious to all animal species, including humans, and has a death rate of up to 10 percent. The smallpox vaccine is said to work well against monkeypox. ¹⁾

It's estimated that 59,000 people die from rabies every year worldwide, mainly in Africa and Asia. Once symptoms appear, the fatality rate is nearly 100 percent as there are no effective treatment options, even with intensive care. As of 2016, there are only 14 cases in the history of people who survived rabies after showing symptoms. However, thanks to the vaccine developed by Louis Pasteur in 1885, it's possible to avoid disease in 100 percent of cases if the vaccine is given within 10 days of exposure. ²⁾
