Edward Jenner vaccinating a boy - Oil painting by EE Hillemacher, 1884.
Edward Jenner successfully vaccinated a young boy against smallpox in the summer of 1796. He modified the Chinese method of variolation, and the impact of his innovations in Europe at the time are reflected in this painting by Hillemacher, which was first exhibited in the Paris Salon in 1884.
In a way, this painting itself is a public argument in support of vaccines during an era when vaccines were still a novel concept.
