In our modern lives nowadays, due to climate, dust from the environment and diseases, many people are now facing with health issues and infectious diseases. Many proponents say that vaccination is safe and one of the greatest advance science prevention health developments in the 20th century. However, there were many different arguments between its benefits and disadvantages about this helpful prevention method. Nevertheless, due to many arguments and evidence for patient’s cases of prevention from Centers for Disease Control and Prevention (CDC), World Health Organization (WHO) or in any practical health issues, vaccines were invented to prevent illnesses and infectious diseases because the effective means and benefits are far greater.
First of all, the vaccine is an amount of medicine mixed with different ingredients such as antibodies or small pathogen organisms in different uses for diseases. The role of a vaccine is to bring that amount from an injection into our bodies for “good health”, and used to create healthy, active immunity for the body’s resistance. There are many ways to use this “magic prevention” into the patient’s body. For instance, the original and classic way to use for vaccines are given by an injection, however, due to modern technological advances in this century, some cases people can “delivery” the amount of vaccine directly into our mouth or by nasal spray. To be specific, there are few diseases people can apply for oral vaccines like rotavirus or polio. Nevertheless, by entering the number of pathogens through oral route may cause the alive-weakened virus to be active again in our bodies. By taken orally, there are just small quantities of pathogens or medicines but they can go into our bodies and absorbed quickly as they can. However, orally vaccine is not useful enough for the patient because not all vaccines are can be directly oral and most can be injectable. Going to the nasal spray, it is only used to replace flu shots and it’s made from weakened flu vaccines. The instruction for using nasal spray is completely easy, the doctor can spray into the patient’s nose, the medicine can go through the nose down to him or her body in order to protect them from flu season which can be affected easily. In this case, the level of protection between nasal spray and flu shots are the same and safe enough for the patients, it’s up to each person if they want to choose different ways to insert for flu disease. Going to infectious diseases, this kind of disease caused by viruses or small organisms go directly and pass through a body to create symptoms in a range of normal increase to deadly. Some specific infectious diseases such as malaria, HIV, malaria and yellow fever can affect the entire body to cause many symptoms in the patients. Especially, tuberculosis is one type of the infectious diseases for respiration, everyone has to check the tuberculosis test to know if he or she already affected by tuberculosis or not. Because BCG known as Bacillus Calmette-Guerin is a vaccine for tuberculosis can create active immunity against this disease.
Secondly, our powerful prevention method can save many children’s lives from different kind of diseases or infection. Some serious diseases can kill thousands of children because a child’s immune system needs some pathogens or antibodies in vaccines to protect their bodies and health against natural environment, diseases or infection. According to The American Academy of Pediatrics, it states that most childhood vaccines are 90%-99% effective in preventing disease. “The Centers of Disease Control (CDC) estimated that 732,000 American children were saved from death and 322 million cases of childhood illnesses were prevented between 1994 and 2014 due to vaccination.” For instance, there are some diseases like polio, pneumonia, varicella, meningococcal, mumps and rotavirus that are really in need of vaccines. To be concise, polio is one type of disease can infect person to person because the poliovirus lives in an infected person enter to the body and contact directly with the feces. Sometimes, poliovirus can infect a normal person by the small amount of liquid through coughing or sneezing. Therefore, not only children have to had vaccines to protect their health but also the adults, everyone has to prepare their bodies against this poliovirus. Because the result of poliovirus for infected people can lead to paralysis that makes some or all parts of the body can’t move.
Thirdly, vaccines are effective means preventing people from various diseases due to many shreds of evidence for different cases of patients. “As a consequence, WHO estimates that in 2003, 38.3 million cases and 607 000 deaths were prevented by the use of pertussis vaccination”.“However, pertussis is still estimated to cause 295 000– 390 000 childhood deaths annually, with most deaths in countries with low immunization rates and high mortality rates. Further gains can be made by increasing coverage with three doses of diphtheria-tetanus-pertussis vaccine in infancy and the provision of booster doses as appropriate.” The reason why vaccines are effective because it is carefully reviewed and checked by the doctors, scientists or the hospitals before giving to the patients. Moreover, talk about the safety of vaccines is about what are the ingredients people are using and how they activated in our bodies against diseases. One of the most common ingredient scientists or doctors used for the vaccine is thimerosal. This kind of element involved in vaccines that contained mercury has been used for multi-dose vials for the patients. As the term multi-dose vials infer to add more on dose in order to prevent the growth of germs or bacteria can left when a syringe needle enters a vial as a vaccine is being prepared for administration. According to the Journal of Pediatric Psychology in January – February (2012) by Barile JP, Kuperminc GP, Weintraub ES, Mink JW and Thompson WW about the study of brain function, behavior, language, coordination, and thimerosal. “This study assessed whether prenatal thimerosal exposure or thimerosal exposure between birth and 7 months of age was associated with seven specific neuropsychological outcomes in children ages 7-10 years.”After the investigation, the result wasn’t getting any positive connection with thimerosal that affected the function of brain or parts of body, memory, behavior or language of the children. Accordingly, they can prove thimerosal is not a toxin ingredient in vaccines, but merely a preservative, preventing contamination, that has been used in vaccines for decades.
Fourthly, the important role of vaccinated people has been decreased the infection of several diseases. That leads us to the understanding of herd immunity is related to vaccination. Herd immunity is a term represents for keeping away infection of diseases for both vaccinated people and people without immunizations. The deeper meaning of herd immunity is when the percentage of vaccinated people increase in a community, the decrease of infectious diseases contact with people will go down. According to a source form the US states in 2011, 49 US states did not meet the 92-94% herd immunity threshold for pertussis (whooping cough), resulting in a 2012 pertussis outbreak that sickened 42,000 people and was the biggest outbreak in Washington. It clearly shows that vaccines provide an appropriate amount of herd protection for individuals who have not developed immunity. Especially, if the rate of vaccines declined down to the accurate herd immunity, there will be widespread of diseases outbreaks can happen to a community.
Last but not least, leading up to vaccine-preventable diseases have not disappeared and many cases of patients are still available in different countries in the world. There are still many diseases such as rotavirus, meningitis, pertussis, tetanus, measles and many more diseases caused thousands of people level of infection from mild to deadly which certainly demonstrated that vaccines are necessary prevention method for people’s lives. Moreover, vaccines had been destroyed smallpox and other diseases such as polio. “The CDC mentions that many vaccine-preventable diseases are still in the United States and other countries. Despite the fact that the form of polio has hugely expired thanks to vaccination, the virus still available in many special countries like Pakistan where there were 93 cases in 2013 and 71 in 2014 as of May 15.” 
In contrast, with many benefits arguments of vaccination, there are still many ideas and disagreement about this “magical prevention method” for people’s health. Although vaccines are safe for patients after injected, some cases people get many symptoms such as feeling uncomfortable in eyes or cause pain, trauma or allergic, but they are very rare in almost time. To be more serious, vaccines are not safe which linked the patient to autism. It is a symptom of the uncontrolled behavior of activities and way of thinking that is completely different to other normal people. Autism is a really harmful symptom for people because it makes us can’t control our attitude, characterization reaction as normal life of normal people. “As reported by a study from Journal of Toxicology and Environmental Health published in 2011 has confirmed a positive correlation between the proportion of children who received vaccinations in each state over the interval from 2001 to 2007 and the incidence of autism or speech and language impairment.” “For each 1% increase in vaccination rate, 680 additional children were diagnosed with autism or speech delay.” Those sources are recorded by various of studies which prove that the ingredient of vaccines is also contained harmful elements that lead to the consequences of autism for people. Not only thimerosal is the ingredient which people used to make a vaccine, but also another element like aluminum. Many vaccines contain aluminum salts such as aluminum hydroxide, aluminum phosphate or potassium aluminum sulfate. They are inferred for using as the extra medicine or additional dose in order to bolster the immune response to the vaccine in which can cause neurological harm to people. Neurological is all about the disorder of the nervous system in the brain. It linked to brain, spinal cord, all the nerves, and muscles make all of them disarrangement. Therefore, the patients can be faced with many severe symptoms such as Alzheimer’s disease, Parkinson’s disease, etc. Moreover, vaccines are not necessary because the diseases of vaccines target have essentially disappeared. “According to the CDC reported no cases or deaths from diphtheria between 2003 and 2011 in the United States, fewer than 51 cases and 10 deaths per year from tetanus were reported between 1994 and 201, polio has been demonstrated eradicated in the United States since 1979, there have been fewer than 21 deaths yearly from rubella since 1971, and fewer than 25 deaths yearly from mumps since 1968.” Due to those reported, people claiming that all the diseases are becoming declined, so they don’t think vaccines are needed anymore.
Nevertheless, vaccines have greatly reduced the burden of infectious diseases and became an effective means of protecting people by outweigh all of their effectiveness benefits more than their certain risks or side effects might be less chance to caused.
