School vaccinationsIn 1827, in the city of Boston, Massachussetts, the School Committee voted to require, effective 1 Mar 1828, that public school students show that they had been vaccinated against smallpox prior to school entrance. Certificates to the board of health were to be issued where necessary for free vaccination. This initiative came just three decades after Edward Jenner's discovery of a method to immunize against smallpox. The state of Massachussets passed the first school vaccination law in 1855, followed by New York (1862) and Connecticut (1872).«* |
