In this book, he provides a detailed history of vaccination and its development, as well as practical advice on the proper techniques for administering vaccines. Willan also addresses common concerns and misconceptions about vaccination, such as fears of side effects and the belief that it can spread disease. Overall, On Vaccine Inoculation is an important historical document that sheds light on the early days of vaccination and its role in modern medicine.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
