The purposes of this research paper are to evaluate the in-depth pros and cons of the use of vaccines in humans and animals around the world. A vaccine is a substance that is used to help humans and animals fight against pathogens and disease-causing germs (Konkel, 2017). Vaccinations can be both beneficial to saving human and animal lives and may also cause unwanted side effects and disabilities themselves (Fisher, 2017).
In 1796, a doctor named Edward Jenner created the first vaccine on humans, to stop the spread of smallpox disease. Small pox is a disease caused by the variola virus, symptoms include fever, rash of skin that can leave permanent scars, and even death (CDC, 2016). Vaccinations are delivery methods include injection, oral,

Allergic reactions and anaphylaxis are a known side effect of many vaccines that are administered to humans. Anaphylaxis is a severe, multi-organ system reaction that can be life threatening. Anaphylaxis symptoms cause fever, swelling of throat and tongue, and shock. There are six types of vaccines that have caused anaphylaxis, including MMR, varicella zoster (chicken pox), influenza, hepatitis B, meningococcal, and tetanus containing vaccines. The varicella vaccine is known to cause the serious side effects in humans with immunodeficiencies, these side effects include infection after vaccination, pneumonia, encephalitis, and meningitis (Mercola, 2011). Equally important, the MMR (measles, mumps, and rubella) vaccine may cause seizures and short term joint…show more content…
In the past quarter century, vaccines have helped control the outbreak of many diseases, but have caused a spike in chronic brain inflammation and autism. 1 in 6 children have become developmentally delayed, and 1 in 150 have developed autism (Fisher B. , 2013). Autism can develop after the age of 1 or 2, the symptoms of autism include impaired social skills, difficulty responding to stimulation or talking, and have delayed or no speech (NAA, 2018). “Acute brain inflammation, whether it follows infectious disease or vaccination, can become chronic and result in various kinds of mild to severe neurological dysfunction manifested by learning disabilities, ADD/ADHD, seizure disorders, autism, mental retardation, and other developmental disabilities” (Fisher B. , 2009, p. 35). Furthermore, a mercury-based additive thimerosal is a dangerous ingredient found in many vaccines, this additive is used as a preservative (Kaplan, 2017). “Since the 1930s, vaccines have contained thimerosal, a mercury-based preservative that breaks down to ethyl mercury and thiosalicylate in the body. By some calculations, children given the usual schedule of vaccines containing thimerosal receive ethyl mercury in doses exceeding the U.S. Environmental Protection Agency’s guidelines for methylmercury, a known neurotoxicant” (Barrett,
