Abstract: “Nanoparticle vaccines”, an article written by Liang Zhao et al. condenses a large amount of information on the topic of nanovaccinology and presents that information in an organized and straightforward manner, however, it only scratches of the field and the lack of clarity relating to its audience can lead to it being confusing. The article could prove useful to a scientist possibly interested in doing research in nanovaccinology, however it would likely not be any new information for experts in the field.
The article “Nanoparticle vaccines”, by Liang Zhao et al., seeks to condense information regarding nanotechnology and its role in vaccine development. The authors support the use of nanoparticles when developing vaccines, and

Why do the authors think developing these vaccines is so important? Perhaps the authors thinking that developing these vaccines is important could be considered an opinion, but if so, it’s a very broad and nonspecific opinion. What is their reasoning behind thinking these vaccines are so important? What impacts (economically, medically, etc.) could the vaccines have, and do they think the benefits of the vaccines outweigh the consequences? They don’t address these questions, which can again relate to the lack of a clear target audience: what audience are they trying to target, and would that audience have the same questions? It is certainly a negative feature of the article.
One positive feature of the article was its organization; it was clear what topics it intended to touch upon, and it laid out the general plan for the article very concisely. It is used well when Zhao et al. explain how “we (the authors) first survey advances in the types of nanoparticles…then conclude with remarks about the further potential and future prospects for vaccinology” (2013, pg. 328). They set up the course the article would take very early, which made it clear what subjects they wanted to speak about.
However, as a reader, it was quite easy to get lost in the article. Many different aspects of the technology behind nanoparticle vaccines were thrown at the audience at once, and it was almost overwhelming. There is an immense amount of dense material seen throughout the article, from
Here comes our responsibility as team leaders and responsible civilians to educate such people, guide, and help them to know vaccines’ role in prevention and cure of diseases using simplest language possible while meeting face-to-face, organizing campaigns, seminars, and advertising and answering all the queries via world-wide-web, and using latest smart media and technologies. All in all, demand for the affordable and safe treatment has always been a global concern, but thankfully, with great efforts of our dedicated and highly inspired scientists and researchers today we have few vaccines as cost-effective, secure and reliable preventive-therapy. Introduction of vaccines in the modern science has proved to be a boon to the humanity and a major break-through to the conventional treatment methods. Also, if one could avert a disease then he would not need to worry about the cost he might have paid if he has had suffered from
Vaccines have been used to prevent diseases for centuries, and have saved countless lives of children and adults. The smallpox vaccine was invented as early as 1796, and since then the use of vaccines has continued to protect us from countless life threatening diseases such as polio, measles, and pertussis. The Center for Disease Control and Prevention (2010) assures that vaccines are extensively tested by scientist to make sure they are effective and safe, and must receive the approval of the Food and Drug Administration before being used. “Perhaps the greatest success story in public health is the reduction of infectious diseases due to the use of vaccines” (CDC, 2010). Routine immunization has eliminated smallpox from the globe and
What seems to be an occurring problem with vaccines is the amount of misinformation going around. Subsequently, these barriers include preventable diseases, the dangers of vaccines, and the development and treatment of vaccines which don’t result in immunization. Of all these barriers, the lack of
All living things on this earth are subject to attack from a disease-causing agent. Therefore, multicellular animals have dedicated cells and tissues that fight off infectious microbes in order to build immunity. A multitude of specialized cells carries out much of the immune system’s work. Each of these cells is intended to fight off diseases in a particular way. Vaccination, which is one of the methods that is used to prevent germs from proliferating, is subject of many discussions. While opponents believe that most of the diseases such as diphtheria and varicella are not necessarily harmful, and that injecting questionable vaccine ingredient into a child may cause side effects, such as seizures, paralysis, proponents believe that vaccination has been one of the greatest developments of the 20th century. It has served as a protection for the community, and has saved children and parent’s time money.
There is no doubt that the number of vaccines recommended by health care professionals and government agencies has increased rapidly since 1980. Furthermore, vaccines have also changed in how they are made, which is unknown or poorly understood by the general public. While reviewing the literature, this was shown in the article, “Vaccines and Autism: A Tale of Shifting Hypotheses”, by Gerber & Offit (2009), where they discuss how vaccines have changed overtime. The authors state that today a single vaccine use uses less than 200 bacterial and viral proteins or polysaccharides compared to over 3000 immunological components used in 1980. In addition, the amount of protein chemistry and recombinant DNA has also increased. This helps cut back on vaccine-related reactions, because the vaccine only resembles a microbe and doesn’t function on one.
First, the article is current and the author is credible. The article was made in 2014. Espejo is a credible writer because he has wrote many pro/con argument papers, and he is a young adult and children's writer. Next, the article has well-documented facts and sources. Some sources are wall street journal, and National Institute of Allergy and Infectious Diseases. Along with that the article is not biased. Third the essay has pathos, logos and ethos. “”With the arrival of vaccines, numerous infectious diseases that struck hundreds of thousands of people in the United States each year—oftentimes lethally—have been eradicated and nearly forgotten today”(NIDIA)” (Espejo). That is a positive pathos, and also a credible source which is ethos. “In a 2005 study on the economic impact of routine childhood immunization in the United States, researchers estimated that for every dollar spent, the vaccination program saved more than $5 in direct costs and approximately $11 in additional costs to society” (Espejo). That is one of the statistics in this article that is logos. Lastly, the article's intended audience is anyone who wants to know more about vaccines. Overall this article is
They never mentioned why Bliss was the only volunteer selected to be featured in the article. There must be a reason why she was picked out of 80 people to be feature in the article. Although the story focused on Bliss, the author should have added some of the other volunteers in the video. The other volunteers’ reason for volunteering should have been included in the text. Volunteering for an experimental vaccine is not an easy decision, therefore all the volunteers should have been given a platform to share the reason behind their decision. Moreover, there was no details on data analysis or data findings. The author does not inform readers whether or not some participants had dropped from the experiments. Another negative about this article is the author’s failure to discuss the outcome of the experimental vaccine. The article included plenty of essential information, however it did not interpret the study correctly. It feels as if bits of information such as the length or duration of the experiment was missing from the article. The author did not provide any information on how the experiment will end nor what the expected end result will be nor where to access additional information. In addition, it would have been very helpful if the article defined term such as microcephaly because many people do not know its meaning. The provision of the its definition would have facilitated the reading for
Therefore, I felt it was prudent to step away from my normal vaccine articles focusing on the dangers and ineffectiveness of vaccines; or the corruption in the industry; or the draconian and tyrannical bills popping up across the States trying to force vaccinate those who don't worship at the altar of the all-mighty vaccine, and
Vaccines are said to be one of the greatest health developments of the 20th century, saving many lives. That's why the CDC (centers for disease controls) recommends
Let’s start with the most obvious contribution vaccines provide, progress in the medical field. Medical technology has advanced further in the last 100 years than it has throughout history. We live our lives relatively disease-free and we owe so much of that to vaccines. Despite the overwhelming evidence, people still have some questions and concerns, which is okay, so let’s explore the typical misconceptions that come with the topic of vaccines and provide some information surrounding vaccines.
Not everyone is knowledgeable so I thought he could have written more. Although I did like how there were links to other pages that will be helpful and allow us to develop our understanding on this topic of measles. I did learn some things. I learned that 5 percent of vaccinated children can still catch measles which I didn’t like because that means it is not guaranteed to work. I didn’t know Wakefield was the person that started the autism fear from vaccinations. I find Wakefield detestable to put so many children in danger because he wanted to earn money and did not care for the wellbeing of others. I really liked the community immunity. If every child gets a vaccination, no disease can travel from one person to another. No one would suffer if everyone played a part and did what they should have done. This article made me realize I am very fortunate to have the vaccinations for my children because it can give them protection to catching measles. I didn’t want my children to get the vaccinations. Now I realize it is just out of fear from the news broadcast that I heard from which is not even the truth. I wouldn’t want to let fear consume me and do something that would jeopardize my children’s health and
The act of inducing immunity of diseases artificially has been dated back to 10th century China, when smallpox was widespread and regularly lethal. Since then, the world has been revolutionized by vaccines that can prevent people from contracting the most ravaging of preventable diseases. But since the dawn of disease prevention, there has been opposition by those who refuse to vaccinate not only themselves, but their children as well, which defeats the entire purpose of vaccinations completely. Vaccinations are absolutely essential to promoting and maintaining public health.
The authors best argument was the prices, and their comparisons to one another, because if the vaccines are available in more countries, less people can die or become seriously ill with a preventable disease. The author uses all logical and factual appeals to give the reader the knowledge needed to create one's own personal opinion on the topic.
A vaccine by definition is a biological advancement that helps keep you immune from a disease. The history of vaccine did not start in 1796 like most think. Vaccines have actually been around for centuries. There is evidence that Chinese Empires had vaccines around 1000 CE, but these vaccines were nothing like what is around today. Edward Jenner made the first modern day vaccine in 1796. Jenner experimented on a boy and came to the conclusion that if he was injected with cowpox and than exposed to small pox that the boy would become immune. Even though his work did not immediately kill out the disease, Jenner inspired other scientists to find out more about vaccines. There are many ways to make a modern day vaccine. First, they take the virus or bacteria and they grow it in a lab. Next they isolate the disease away from the lab materials, which made it grow. Than, they purify the disease, which weakens it. Also, an adjuvant may be added to help the immune system fight off the disease. Finally, everything is mixed up and is shipped out to its final destination. Vaccines contain different ingredients based on the vaccine but normally the ingredients include, weakened parts of viruses, Aluminum, antibiotics, formaldehyde, adjuvants, proteins, sugars, and preservatives. Vaccines help immunize the body because when the weakened disease is put into the body, the body makes antibodies to fight off the disease. If the real disease ever came into the body, the body would be able to
Over the past seventy years, a major practical problem in medical science was dealing with infectious diseases. Many human communicable infections are caused by microscopic organisms either bacteria or viruses. Immunization is the most outstanding and cost effective means for fighting infection caused by micro -organisms (Ragan & Duffy, 2012, p.22). Like every medication, vaccines have benefits and risks, and although highly effective, no vaccine is 100 percent safe in all individuals. However, adverse side effects of vaccination are significantly less than the risk of the serious illnesses caused by infectious diseases. The effectiveness of immunization
