Vaccine Essay

Vaccines have helped millions of people all over the world, preventing different sickness and diseases. Doctor’s and scientists have come up with hundreds of different vaccines. The way they are made is a process that needs to be very specific. Each vaccine is made differently but all have the same concept.

To understand how vaccines are made, one must understand how they were first invented. The first inoculation, what most people think was in 1796, actually occurred in China in the year 1000. Historians believe that that the “vaccination” was snorting pulverized smallpox scabs. Smallpox and other diseases such as whooping cough, typhoid fever, measles, yellow fever, and many more spread throughout Europe and the New World for hundreds of

Some viruses such as measles, mumps, and chickenpox are used this way. These types of vaccines are used to make the immune system used to the virus in case one is effected. Another way a vaccine is created is by totally inactivating the virus completely. They are killed by a chemical, so it cannot reproduce itself once inserted into a patient. Vaccines for viruses such as polio, hepatitis A, and rabies are made this way. Using part of the virus is another way of how vaccines are made. Hepatitis B and the HPV shot are made this way. One of the last ways to create a vaccine is by using part of the bacteria. Diphtheria, tetanus, and pertussis are created this way. Scientists either take the sugar coating of the virus or they take the toxins and inactivate them with a chemical.

To make a vaccines, scientists begin growing small amounts of the virus, which must contain only the virus, having no impurities whatsoever. Depending on the virus, they must grow in certain temperatures, ensuring that it is made effectively. Once there is enough to of the virus, there is a separation of what is pure to use and what is not. One of the final steps is selecting the perfect strain that will be eventually killed or weakened. The quality of the vaccine is very important, so it must be transferred to hospitals and other locations in a safe way. The vaccinations are then observed and

    Jonas Salk used this knowledge to create two different kinds of polio vaccines. Polio vaccines give lifelong immunity by two ways, by immunization and natural infection with the virus. (Polio Vaccines) There are two vaccines: the oral polio vaccine and the inactivated polio vaccine. “The oral polio vaccine was invented by Albert Sabin in 1961.” (Polio Vaccines) It is a weakened, live virus, which can be taken orally. This vaccine produces antibodies in the blood to fight the virus.…

    Scientists make vaccines by first making the pathogen, or disease-causing microbe, in mass amounts in a laboratory. The pathogens must then be altered to ensure that the disease is not actually triggered. Alterations of these pathogens can be done in different ways. Scientists can weaken the pathogen by growing it over and over and selecting a strand that is less dangerous, take out the part of the pathogen that causes the immune response and use it in the vaccine, or use the toxin that the pathogen makes then inactivate it (Tetanus vaccine). Finally, the treated pathogen is combined with things such as stabilizers and preservatives to then produce the actual vaccine dose.…

    Vaccinations are used to make someone immune to an infectious disease. To trigger an immune system response, how the body responds to diseases, vaccines are loaded with microorganisms, a microscopic organism. A common vaccine consists of a weakened pathogen, an organism that causes diseases. The pathogen could also have been altered so that it cannot cause illness. When a vaccine is administered, pathogens enter the body.…

    Both of these methods were used on healthy children since once you acquire the smallpox disease you are automatically immune to it. Inoculation differs from vaccination based on the virus placed inside the body. A vaccination is performed with a weakened stand of a virus. The immune system is then triggered to protect the body if it was to come into contact with the virus. Inoculation on the other hand is the direct virus being place inside the body.…

    The main argument for this link is the Thimerosal compound found in vaccinations. As defined by the CDC, Thimerosal is “a vaccine additive, added to some vaccines to prevent germs (like bacteria and fungi) from growing in them.” I set out to find if there as a possible connection between Thimerosal and Autism. Quickly, I found a journal studying the two topics that left me in confusion: Autism and Thimerosal-containing Vaccines. Their conclusion claimed that “…the evidence is inadequate to accept or reject a causal relationship between exposure to Thimerosal from vaccines and … autism… . [However,]…the hypothesis is biologically plausible.” (P.106) The study concluded that although it didn 't find any concrete evidence pointing to a link, they…

    Vaccines are made to fight off viral viruses as well as disease pathogens. Pathogens entering a body will allow the body to use antibodies to fight off the virus, but even if your antibodies work, they might not work completely. Becoming sick, however, does not mean that the antibodies are not working. It simply means that the antibodies are working to take care of…

    People can get immune by getting the disease and having the body fight it with the risk of getting sick, or they can get a vaccine that can help you develop immunity without getting sick. According to the Children’s Hospital of Philadelphia Vaccine Education Center, “Vaccines are made of dead germs or weakened antigens. They can’t cause an infection but the immune system still sees them as a possible enemy and produces antibodies in response.” After the immune system makes antibodies there is something called a memory cell that is produced. If the body were ever to be exposed to that same virus again the immune system notices it and sends out the right antibodies to fight the infection fast and efficiently. Someone who is vaccinated can also help others who are not vaccinated.…
