They work by utilizing a variety of substances to defend the human body against potentially deadly microorganisms (“Vaccine” 1). Vaccines operate by introducing a weakened version of the virus, or a strand of a protein from the bacteria into the immune system. In turn, this insertion causes the production of antibodies which help to fight the actual infection, by attacking the virus upon its entry into the body (“Vaccine” 1-2). Previously, vaccines revolved around observations that humans will develop an immunity to a disease they are exposed to, given they survive (“Vaccine 1). However, vaccinations are far
If the organisms did not very active, the mild infection will respond to rest and home remedies. However, some organisms which reproduce rapidly and cause life-threatening infections may require hospitalization. Many infectious diseases such as measles and chickenpox can be prevented by vaccines (Nordqvist. C, 2017). Taking a good care on the basic hygiene such as frequent and thorough hand-washing also helps protect from most infectious diseases.
For example, polio vaccine contains poliovirus. But the antigens in vaccines are weakened to the point that they don’t cause disease. However, they are potent enough to make the immune system produce antibodies that lead to immunity. The person gets protection without having to get sick. Through vaccination, people can develop immunity without suffering from the actual diseases that vaccines prevent.
Inflammation in most cases is of great value and a normal response to injury. This is how the body floods the area with oxygen, nutrients, antibodies to fight off invading organisms, and fibroblasts to carry on the wound-healing processes to the injured area. You may, however, see how sustained levels of cortisol in the bloodstream may actually interfere with the natural healing process and progressively decrease the body’s resistance to infections, swelling, and tumors of all
In addition, phages can also overcome host resistance mutations. However, they can be eliminated by the body's defense mechanisms. Phage therapy has been used as an alternative to antibiotics. The use of natural phages to treat bacterial infection has very known history in the western medicine. Antibiotics are one of the most successful forms of chemotherapy in the history of medicine.
The bacteria associated with penicillin, has originated from rare and naturally resistant varieties that had prevented the killing of the bacteria and as a result, making the drug ineffective. The resistance towards penicillin was due to the high number of antibiotic-resistance bacteria present which had a greater chance of survival over the bacteria that was not resistant, therefore being preserved and eventually causing a mutation in the bacteria not already resistant to penicillin (De
In order for vaccines to work appropriately, they have to operate in a very convoluted way to make sure they live up to their standards. 1. Vaccines are developed by using the bacteria’s specimen that has been either killed or damaged which are dissolved in a solution. When the vaccine is injected into the body, the specimen revives that person’s immune system. After being injected, the immune system will now fight against the microbe by forming antibodies.
Fleming did not plan on revolutionizing medicine, but he did and it made one of the biggest impacts in medicine. Antibiotic, a chemical substance produced by micro-organisms which has the capacity, in dilute solution, to inhibit the growth of or destroy other micro-organisms (A. Porteous, 2008). Antibiotics are used to treat and control infectious diseases in the human body, animals, and even
After treatment, addition, new blood vessels may develop. The photodynamic therapy also aims to destroy the fragile blood vessels, but this is achieved by injecting a drug that adheres to the surface of said vessel, and subsequently illuminating the eye with a light that activates the drug. The activated drug destroys blood vessels only, without affecting healthy tissues. This treatment does not restore lost vision, but retards the progress of the disease. A recently developed a new treatment for macular degeneration with very good results in general (although there are people who do not respond to this treatment), which is based on the use of injections periodic anti-VEGF (vascular endothelial growth ), they are hindering the development of new vessels, which is the alteration that really worsens the prognosis of the disease.
Do you think vaccination is important? Vaccination is very important because it is the most effective way to prevent an outbreak of infectious disease. Vaccination is the introduction of vaccine or antigenic material into our body to incite our immune system to fight with the pathogen and acquire immunity towards the disease that is caused by the pathogen. After the vaccine is successfully introduced into our body, it can protect us from infectious diseases. Vaccination can be called effective and successful if the disease is eradicated and one of the ways to achieve it is by achieving herd immunity.
