DThere is a lot of talk and speculation about the vaccine these days. When will that long-awaited salvation finally come from the end of the crown? What is the order of priorities, risk groups and health workers first, but then? Will our children be included as well? While we wait for the information, there are other more general questions that can be answered. For example, how long have we inserted people against diseases.
It all started the fear of the smallpox, one of the greatest killers in the history of the epidemic, a plague that has plagued kings and the poor since ancient times. The fear of the chestnut initially gave rise to popular experiments, called variations (later smallpox, the Latin name for the smallpox). The starting point was to realize that once those who received the disease and survived could not get it again. Variolation involves deliberately infecting healthy people with the desired form of smallpox that caused immunity. No one knows when or where such experiments began, but it probably happened in the Middle Ages. Various varieties are known from folk medicine in China, the Middle East, Europe and Africa. The most common method in Europe was to tear the skin and bring the liquid down the patient’s throat. If done by a wise hand, it has given a mild infection, causing only 1 to 4 percent of cases of death. It may seem like a lot, but since the fear of smallpox was so great, many were delighted to take the opportunity.
