The definition of invention is “the action of inventing something, usually a process or device,” according to the Oxford Dictionary. Many inventions have been created over time, from the stone tools of the Stone Age to the electric toothbrushes of our current era, the Age of Big Data. Most of these inventions are created to make our lives easier, but there is one invention that was created to save millions of people without any discrimination, from the rich to the poor. Vaccination, as defined by the Oxford Dictionary, is the administration of a vaccine intended to stimulate the immune system of the administered individual so that it naturally develops antibodies to fight disease, so that when the he individual is in contact with the disease, he already has the antibodies in his body to fight against the diseases. fight disease. This prevents the individual from being affected by life-threatening diseases because the body already has the antibodies needed to fight the disease. Vaccinations have been proven to be the most effective cure for infectious diseases because they prevent the disease from affecting the vaccinated person. Vaccines are the greatest invention ever created. In this essay, I will argue that vaccines are the most important and grandiose inventions ever created. They saved the lives of humans, animals and plants. Diseases such as smallpox, polio and measles, once thought to cause the eradication of life on Earth, have now been controlled through the effective distribution and use of vaccines. Not only has vaccination saved lives, but it has also saved the economies of some countries. Say no to plagiarism.

The smallpox vaccine was the main contributor to the eradication of smallpox. The World Health Organization states that in 1967, 60% of the world's population was affected by smallpox and one in four affected patients died. According to Fenner (1988), those who survived were scarred and/or blind for the rest of their lives. Smallpox was declared eradicated by the World Health Organization in 1980, with the last known case occurring in 1977 in Somalia. Thanks to the vaccination created by Edward Jenner, millions of lives have been saved thanks to a very cheap and accessible invention, vaccination. only affect the health of humanity, but also create a significant dent in the economy of countries. There were fewer people in the job market as the epidemic left millions dead or blinded. This generated less revenue for the affected countries. Although smallpox vaccines were inexpensive, all affected countries purchased tons of them because large numbers of people needed to be vaccinated during the smallpox outbreak, which caused a breach in the capital of country. The combined effects of vaccine costs and a shrinking workforce have a significant impact on a country's gross domestic product. Even though spending on vaccines was high during epidemic phases, they helped the economy in the long run as more people were able to return to their daily lives in the job market. Vaccines prevent the disease from infecting the individual, so it is cheaper and safer than curing the disease. The eradication of smallpox was only the beginning of this revolutionary invention.Diseases once thought to be incurable and life-threatening now had a chance of being eradicated from the face of the Earth. According to UNICEF statistics (2018), 9 million lives have already been saved each year through vaccination and an additional 16 million lives could be saved each year if vaccines are deployed effectively. UNICEF says polio and measles may be the main causes. next diseases that can be eradicated thanks to vaccines. Polio and measles currently cause around 2 million deaths worldwide. If vaccines can be distributed efficiently and as quickly as possible to communities affected by these diseases, polio and measles could resemble smallpox, a disease of the past. Unfortunately, humans are not the only living organisms affected by bacteria and viruses. Animals and plants have been affected, and since livestock and crops are a source of food for us, we are also affected. Farmers are directly affected because livestock and crops are a source of income for them. Some animal diseases can easily spread to humans and farmers if they have direct contact with them, so they are at higher risk of becoming infected. Loss of livestock and crops can negatively impact countries that rely primarily on the agricultural sector for their gross domestic product. Vaccines are extremely important during outbreaks of infectious diseases in livestock and crops as they affect the entire country. It is cheaper to prevent disease by vaccinating crops and animals rather than trying to cure the infection after it has already infected populations. The effects of vaccination are so incredible that without vaccines, the agricultural sector will not be able to cope with the loss of income when a new disease hits the region and destroys livestock and crops. Smallpox was eradicated from livestock through vaccines at the same time it was eradicated. in humans. Rift Valley fever is a viral disease of livestock that recently caused an outbreak in 2010 in South Africa and other neighboring countries. Since it is an airborne disease, it is quite difficult to contain the disease, leading to great losses for farmers, according to an article by the World Health Organization (2018). The disease also spreads easily to humans from affected animals via mosquitoes and the animals' bodily fluids. This had a major impact on sheep farmers in South Africa, who lost their assets because the affected animals could not be sold for their meat. After vaccines were injected into unaffected livestock, farmers' losses began to decrease because they were no longer newly infected livestock. Importing vaccines from other countries resulted in significant expenses for farmers, but in the long run the vaccines were cheaper than curing already infected animals. According to Walter (2018), creating plant vaccines is the next step for scientists. There are many diseases, viruses, fungi and insects that kill crops, creating drastic losses for farmers and food security problems, especially on the African continent, where a balanced diet cannot be accessible to a large population . Creating vaccines against crop diseases means that fewer farmers will need to use pesticides, which will improve crop quality and reduce diseases that pesticides are known to cause in humans, such as cancer.
