Live Attenuated Vaccine Essay

The prevalence of disease in the thirteenth century was very common in Europe,and Africa, later on spread to parts of Asia. Currently the bubonic is not that common but is still infecting a small portion of the earth. The Bubonic Plague is an infectious disease caused by the bacteria Yersinia Pestis, a zoonotic bacteria, usually found in small animals and their fleas. It is transmitted between animals and humans by the bite of infected fleas, direct contact, inhalation and rarely, ingestion of infective materials.

Through the rise of technological advances in medicine, the vaccine has changed the world for the greater good of the human race. Making a great triumph and virtually eliminating an array of life-threatening diseases, from smallpox to diphtheria, thus adding approximately thirty years to many humans’ life spans. Although, a new complication has arisen, possibly linking neurological digression with this rise of new vaccines. Such a digression has forced parents to exempt their children from receiving vaccinations and brought forth mental anguish affecting the minds of many.

The Bubonic Plague or ‘Black Death’ is a highly infectious and potentially fatal disease that spread rapidly throughout Europe in the Middle Ages. The disease carrying Bacterium, Yersinia pestis, caused millions of deaths in the 1300s due to its highly contagious nature. Many people contracted the Bubonic Plague from bacteria carrying fleas, which carried the plague bacteria from an infected rodent (A.D.A.M, 2015). This particular disease isn’t usually spread from person to person, but instead through small rodents and animals that carry infected fleas, many people became infected from flea bites or direct contact with the infected skin or fluids of an animal, (Rare Diseases, 2014) However, according to some credible scientists, it is believed

The bacteria found in the Black Plague is known as Yersinia pestis that is a bipolar and plump, lightly-staining, coccobacillus. Remaining a dangerous threat even today as well as what was previously stated that it is a plausible agent for bioterrorism. And as stated, areas such as America, Asia, and Africa are foci endemic areas. Where wild rodents, such as squirrels and rats, are the sustenance pushing for the spread and infection of the disease. The transmission being from animal-to-animal through fleas and infection to humans through contact or bites. Instances of human-to-human infection are uncommon except for the pneumonic plague, the disease caused by plague bacillus also known as Y pestis. The germ was named after Alexander Yersin who had discovered it in 1894 during a pandemic in China that started in1860. Causing numerous casualties by how fast and effective the disease was spreading, it had seemed that there was no end in

It would travel person to person through the air as well as through the bite of infected fleas. Most medical historians believed that this germ was spread in many different ways but the respiratory form was what caused the deaths of most of its victims. The military then and now used the plague as a war weapon. “As a highly contagious disease with an extremely high mortality rate, if left untreated, Yersinia Pestis has been used as biological warfare for centuries. Some warfare strategies include catapulting corps over walls, dropping infected fleas from airplanes and areosaling the bacteria during the cold war. More recently the plague raised concerns as an important national security threat because of its potential use by terrorist.” (Stenseth, 2008, para 8). They would also put infected rats as well as flies into water sources. Although the plague had run its course by the early 1350’s, it has reappeared every few generations ("black death," n.d.). According to many historians’ the plague has permanent homes in Asia, Siberia, China, Iran, Libya, Arabia and East

With the increase in travel in the world, citizen in countries that are inaccessible to vaccination might trigger a plague again. 2. Supporting evidence: Transition: Action

I, like citizen three, am undecided on government imposed vaccination. I don't personally agree with citizen I, point of view; but I do agree that people who do not get vaccinated are putting other people in danger. The same goes with citizen II, as a person who strongly believes in freedom of will, I can see why she opposes this issue. But at what price? At the price of others health? I think with an issue like this, it would be extremely selfish to oppose the vaccination.

Plague is an infectious disease that is caused by the bacterium Yersina pestis. Depending on lung infection, or sanitary conditions, plague can be spread in the air, by direct contact, or very rarely by contaminated undercooked food. The symptoms of plague depend on the concentrated areas of infection in each person: bubonic plague in lymph nodes, septicemic plague in blood vessels, pneumonic plague in lungs. It is treatable if detected early. Plague is still relatively common in some remote parts of the world.

The “Black Plague” is a term applied to an infectious disease that is caused by a gram negative organism called “Yersinia pestis”. Rodents ,such as rats, squirrels, rabbits, cats, mice etc., are the main source of origin for this bacteria, the bacteria itself being spread between animals by their fleas. The bacillus has been prevalent in wild rodents in the continents of Europe and Asia for many centuries, and the disease has, at times, devastated inhabitants and influenced the course of history. Major outbreaks in the human population mainly result from exposure to rats that are infected. While there is only one bacteria causes plague, it can affect people in three different forms: Bubonic, a form characterized by swelling of the lymph

The Yersinia Pestis bacterium, better know as the black plague, is known for taking millions upon millions of lives throughout human history. Poor living conditions and sanitation are favorable in the quick spread of the disease, which is why it spread like wildfire in the middle ages. In today's society, however, contracting the bacterium is almost unheard of. But even with all the medical advances we have today, a mortality rate of 30-75% still haunts over those infected.

The source is a parasite that has carried the bubonic plague for over 600 years.This source is a primary because this is a parasite that has the Bubonic Plague from the Black Death. My source tells us that the bubonic plague from the black death existed and that it can help us understand the disease. Such as the cause of the disease, where it came from and the symptoms of the disease. We can also track down how much blood and how many rats blood it took. This helps us find a end to the plague. 25 million people died from this tiny parasite, thats over the population of Australia. Yersinia pestis is a zoonotic bacterial infection transmitted by a flea parasite. The plague infection is typically spread from one rodent to another after

plague, caused by bacterium Yersinia pestis, were used as projectiles and fired from catapults to infect

There are millions of sicknesses and diseases spreading around the world every single day. That means that every person has the chance of contracting these diseases. What if there was some way to prevent people from getting these diseases? Actually, there are vaccinations that can prevent many illnesses. Many vaccinations should be given to children, and parents should be sure to get their children vaccinated to try and prevent an outbreak of a Vaccine Preventable Disease (VPD).

disease to occur with numerous antigens entering the body at once and that their child will not be able to properly metabolize and excrete the mercury from their body.

Yersinia pestis, is well known for being the cause of the bubonic plague; the cause of the black death that plagued medieval Europe. What is not nearly as well known, is that there are actually three different forms a Y. pestis infection can take: pneumonic, septicemic, and bubonic. How Y. pestis infects the body and why it is so deadly are also largely unknown with regards to most people’s knowledge of the subject. Much research has gone into this bacterium and the body’s response to the foreign invader. The bacterium is still relatively common in parts of sub-Saharan Africa, so a greater knowledge of this microbe is imperative for humans to be able to stay safe considering the danger
