Victorian illustration to download showing a picture of a District Vaccinator vaccinating mothers, children and babies against smallpox in a crowded hall in the East End of London. This picture was drawn during the smallpox epidemic of 1870-72, which resulted in 42,200 deaths. During the epidemic children were given half-holidays from school so that they could be vaccinated, and vaccinators went to factories, police stations and even jails. Free vaccination of children had been introduced in 1840, and by 1871 vaccination was compulsory for all.
