Vaccines can be defined as a substance that provides immunity against diseases by stimulating the production of antibodies. Vaccines are made from the causative agent, in other words, the same virus that causes the illness is used, but it is weakened and treated to act as an antigen without causing harm to the body. When vaccines enter the body, the immune system remembers the virus. Therefore, if that same virus entered the body, the immune system would have already developed antibodies against the virus and would be able to fight off the disease. Vaccinations generally protect the body from diseases that may cause disabilities or fatality.
This dosage would not get you ill be just enough for you body to have reactions and make their own antibodies. A toxoid is a vaccine, which consists of weakened toxins instead of the weakened or dead pathogens themselves. A serum is a substance used for artificial passive immunity. Antibiotics are something produced by an organism to prevent or slow down the growth of pathogens. Some commonly used antibiotics would be penicillin, erythromycin, streptomycin, neomycin, and terra mycin.
There are many but I’m going to explain to you the different types that have been created especially for the specific virus or bacteria they are meant to prevent. There are live, attenuated vaccines this type of vaccine contains a version of the living virus that is weakened so that it cannot cause the disease in people with healthy immune systems. (Measles Mumps, Rubella MMR, Varicella are examples.) Inactivated Vaccines is the next type these are made of inactivated or dead viruses with these though multiple doses are often required to build up immunity. (Polio Vaccine is an example.)
A vaccine is a manufactured drug, that helps your body fight of certain diseases, a vaccine is usually made by using a weak version of the virus or illness that is taken into the body so that your white blood cells can get trained for when the actual threat comes. The website www.wikipedia.com defines a virus as "A biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins." The first ever vaccine was created at around 1796 by a man named Edward Jenner who created a vaccine for smallpox by using cowpox. He did this by observing that those who have had cowpox couldn’t get smallpox.
This may seem like a logical way to defend our health, but by doing this we are bypassing natural IgA immunity, our first –line defense against harmful pathogens. IgA is found in mucosal tissues and works to defend against invading pathogens and other enteric toxins by blocking their attachment to epithelial cells. Eliminating this element from our natural immune system often causes our bodies to over react to vaccines, sometimes creating unwanted effects (Mantis, Rol, & Corthésy, 2011). It is well known that vaccines can cause many different side effects. Once you have received a vaccine, it is highly recommended by the CDC to monitor for sever, life-threatening symptoms.
A vaccine is a biological preparation that provides active acquired immunity to a particular disease. It normally contains an agent resembles a disease-causing micro-organism and is often made from a denatured form of the targeted virus. This activates the body’s immune system to recognize the agent as a threat, destroy it, and the keep a record of it. Keeping a record of the agent is essential because this how the body can more easily recognize and destroy the virus if it is contracted later in life. Like stated before, vaccines are dead or inactivated organisms or purified products derived from them.
Parents and patients are revealed to a lot of false information. They here in the media, the news, the internet, and the public; false information about vaccines. Even parents that c... ... middle of paper ... ...ic achievements in the United States during the 20th century.” (Risk vs. Benefit) Without vaccination we would lose our friends and family each day. There are vaccines that have eliminated poliomyelitis in America; and has controlled measles, rubella, tetanus, diphtheria, and other infectious diseases.
Furthermore, in the 1930s, vaccines against many diseases such as tuberculosis and typhoid developed. More recently however, vaccine research and development led to a vaccine for polio ("All Timelines Overview," n.d.). When creating a vaccine, the goal is to weaken the virus in order for the person suffering to develop immunity to it. When the vaccine is inserted into the body, it is programed to create Memory-B Cells, which protect against additional infection (Offit, 2013). The chemicals often found in a vaccine include a suspending fluid such as sterile water, a preservative, and an enhancer that helps advance the vaccine's efficiency.
There are many reasons why babies, children, adults and elders should be vaccinated. Diseases (like polio) are becoming rare in the U.S. Of course, they are becoming rare largely because we have been using vaccination to defend against them. Unless we can completely stop the disease, it is extremely important to keep vaccinating. The CDC also states that even if there are only a few cases of the disease today, if we take away the protection given by vaccination, more and more people will become infected and will spread disease to others. Soon we will undo the progress we have made over the years.
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). Vaccines were based on observations that humans will develop an immunity to a disease they are exposed to, given they survive (“Vaccine 1). However, vaccinations are far more safe as they are manipulated to prevent contraction of the given disease (“Vaccine 2).
