The New York Board of Health established a vaccine farm in Lakeview, New Jersey. Lymph from calves infected with cowpox virus was harvested and used as vaccine. The use of animal lymph reduced transmission of human illnesses such as leprosy and syphilis.The Wyeth strain of vaccine was later derived from this vaccine.
- 19th century smallpox vaccination instruments
A physician or other vaccinator used instruments like these to score the flesh on the arm prior to applying the inoculating material to the wound. In the early- and mid-1800s, the material usually came from the vesicle of a previously vaccinated infant. Later, lymph from calves would replace humanized lymph.
