Mandatory and recommended vaccinations for children
The patent for the first vaccine is related to English surgeon Edward Jenner, who, by chance, turned to experimenting with the inoculants, resulting in the smallpox vaccine he invented in 1798. The first compulsory smallpox vaccine was introduced in Hungary in 1876. In 1967, approximately 10 million people contracted the disease, and as a result of the subsequent vaccination program, smallpox is now an infectious disease that has been eradicated worldwide.
