The intention to delay or avoid vaccines that are recommended by the Advisory Committee on Immunization Practices can be described as “vaccine hesitancy.” While outright refusal of all vaccines is uncommon, hesitancy is seen on a regular basis in most primary care offices, resulting in immunization delay and prolonged susceptibility to preventable disease. Vaccine hesitancy also could lead to a resurgence in vaccine-preventable infections. Factors such as social media, past experiences with vaccination services, complementary and alternative medicine, and moral or religious convictions can influence decision-making regarding vaccines. We discuss these factors in detail and suggest interventions to reduce vaccine hesitancy. © 2014 Elsevier Ltd. All rights reserved.
1. Introduction According to the CDC about 2.5 million of the 10.5 million deaths worldwide per year among children (age < 5yrs) are caused by diseases for which vaccines are available [1]. Before the middle of the last century, diseases like whooping cough, polio, measles, haemophilus influenzae, and rubella struck hundreds of thousands of infants, children and adults in the U.S. [1,2]. Thousands died every year from them [1]. As vaccines were developed and became widely used,
Protecting a child’s health is very important to parents! That is why they should vaccinate them as young children. All children should be required to have vaccinations in order to start school in every state. Each year about 85% of the world’s youth receive vaccines that protect them against several diseases like tuberculosis, pneumococcus, and many more. Even with great success and improvements with vaccinations, more than 3 million people die each year from
All too often we hear on the news of the devastating effects of a disease that could have been prevented by vaccines, but because of parents refusal to vaccinate their infants and children, public health professionals are now confronted with a health crisis. The importance of vaccinations is to provide children with added protection because of a young, developing immune system. Consequently, vaccines will help in boosting the immune system in recognizing and protecting children from vaccine-preventable diseases, such as measles, mumps, and pertussis, also known as whooping cough.1 For example, pertussis, a bacterial infection that is preventable by vaccines, has infected 16 million persons worldwide, and causes about 195,000 deaths
Protecting a child’s health is very important to parents! That is why they should vaccinate them as young children. All children should be required to have vaccinations in order to start school in every state. Each year, about 85% of the world’s youth receive vaccines that protect them against several diseases such as tuberculosis, pneumococcus, and many more. Even with great success and improvements with vaccinations, more than 3 million people die each year from vaccine-preventable diseases. An estimate of about 1.5 million of these deaths are in children less than five years old. Of the top ten reported cases of those deaths, several are infectious. (Global Immunizations: Worldwide Disease Incidence, 2017). However, some parents feel vaccines are not safe because they are convinced vaccines are the cause of autism. Nevertheless, Vaccinations are very much necessary. There are many benefits to vaccinating children early. Immunizations should be mandatory because they can save a child’s life, save families time and money, and eliminate diseases forever.
Many infectious diseases that once quickly spread and easily killed have been controlled or eradicated due to vaccinations. The efficacy of vaccines in reducing morbidity and mortality, particularly in children, is undeniable. Per the World Health Organization, childhood vaccinations prevent approximately 2-3 million deaths per year worldwide (WHO, 2016). In the United States, the value of immunizations is clearly displayed by comparing pre-vaccine era morbidity/mortality rates to post-vaccine era in regards to vaccine-preventable diseases. For example, prior to the diphtheria vaccine in the 1920’s, 206,000 people annually contracted the disease resulting in 15,520 deaths (History of Vaccines, 2009). However, between 2004 and 2014, only
Despite significant progress in the fight against preventable disease, millions still die needlessly each year. According to UNICEF, originally known as the United Nations International Children’s Emergency Fund, a vaccine preventable disease is responsible for 2 million fatal infections worldwide each year. About 75% of these deaths occur in children under five years of age. (N) In more vivid terms, UNICEF notes that vaccine-preventable diseases kill a child every 20 seconds. (D) Due to high rates of childhood vaccination, the United States has experienced a dramatic reduction in such deaths. A comparison of the years 1950 and 2010 clearly illustrates the benefits of vaccinations. During this 60-year period, deaths from diphtheria reduced from 410 to 0, tetanus from 336 to 3, pertussis from 1,118 to 26, and polio from 1,904 to 0. Measles deaths dropped from 468 in 1950 to 0 in 2008, the last year a United States death rate was recorded. It’s not surprising that vaccinations have been touted as one of the top ten health achievements of the 20th century by the Centers for Disease Control and Prevention (CDC).
The most commonly cited reason why parents decide to not vaccinate their children is due to their belief that vaccines cause harm11. In a survey that looked at risk perception with vaccines, researches found that while 94% of individuals surveyed had vaccinated or plan on vaccinating their children, only 23% of participants had no concerns about the vaccines16. This reiterates the point that even though there are high rates of vaccination in the United States,
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
“As healthy as my lifestyle seemed, I contracted measles, mumps, rubella, a type of viral meningitis, scarlatina, whooping cough, yearly tonsillitis, and chickenpox, some of which are vaccine preventable” (Parker 1). This quote by vaccine advocate Amy Parker, a woman who was not vaccinated as a child, shows just a glimpse into the life of an unvaccinated individual. Parents who do not vaccinate their children claim many different reasons for their decision. Three of the most popular reasons are: religious grounds, health problems as a result from vaccines, and the belief that the illnesses are rare. Each of these reasons can be proven as nonessential in the anti-vaccine argument.
Vaccine controversies have been ongoing for the past eight decades. Some parents are hesitant to vaccinate their children because they question the effectiveness, necessity, and safety of vaccines. The hesitancy or refusal to vaccinate is called vaccine hesitancy. Vaccine hesitancy has been increasing over the past few decades due in part to the impact of social media, specifically the Internet. Vaccine hesitancy can cause refusal of parents to vaccinate their child. The more children that are unvaccinated, the less herd immunity that is generated in the community. By increasing the number of children vaccinated, despite the vaccine hesitancy enhancing effects of the Internet, herd immunity can be generated, and this can be cost-effective.
The source I located is entitled Calling the Shots: Why Parents Reject Vaccines. This book begins with an introduction that recounts a story of a little girl suffering from cancer who almost passed away from contracting a virus that could have been prevented had others who were able to receive immunization did so. This story focuses on the danger that unimmunized children bring to children with compromised health. It goes on to speak about where parental rights end and government rights begin and all the immunization laws that have ever been in place in America. Further in the book, the idea of rights is explored and how mandatory vaccinations would infringe upon the inherent authority parents have over decisions involving their children. Topics
“In 2011 alone, 1.5 million children died [worldwide] from diseases preventable by currently recommended vaccines” (“Immunization” 2). The magnitude of this tragedy is in part caused by the fact that some of those children simply weren’t reached by organizations like UNICEF, which aim to vaccinate children (“Immunization” 2). However, there are other reasons for the recent deaths and epidemics—such as the whooping cough epidemic of 2012, with 48,000 cases nationally in the United States—involving vaccine preventable diseases (McClay 1).
Immunizations were created to keep children and adults healthy and safe. Edward Jenner administered the world’s first vaccination known as the smallpox vaccine, which had killed millions of people over the centuries (). Jenner administered the vaccine on an eight year old boy who he exposed to the fluid of a cowpox blisters, the boy developed a blister which eventually went away. Jenner then exposed the boy to the smallpox disease and the boy did not get sick, this led to the smallpox vaccine and the drastic decline in the smallpox disease. Fast-forward three centuries later and the small pox diseases is eradicated do to people receiving the vaccine. Immunizations are extremely important to the world’s overall health. Babies and children are most vulnerable to disease because they are son young and their organs and bodies are growing at a rapid rate. It is important for children to be immunized against vaccine preventable diseases such as: rubella, diphtheria, and pertussis (whooping cough), and a host of other diseases. High vaccination coverage has significantly reduced vaccine-preventable disease morbidity and mortality worldwide, especially among children (Baggs et. al., 2011). While some people focus on the cons of vaccinations, there are many pros to children receiving vaccinations.
Throughout history, it has been shown that vaccines make a significant impact on the health of our communities and “administration of these vaccines led to dramatic reduction in the number of cases of, as well as deaths from smallpox, polio, diphtheria, pertussis, measles, mumps and preventable diseases” (Jacobson, 2012, p.36). Generally, those involved in campaigns for and research in these preventable diseases attribute vaccines for children as the main contributing factor to the overall decline in diseases such as measles, mumps, smallpox and pertussis (Jacobson, 2012). In the public health setting, there are many issues that threaten the health and safety of the public, not just in the local community but the nation and world-wide. One such issue, surfacing in public health, is the issue of vaccinations; those who choose to vaccinate, those who choose not to vaccinate and those who do not
According to the AAP vaccine refusal is a growing concern in the United States, because of the growing concern
The Center for Disease Control describes vaccines as the greatest development in public health since clean drinking water. For several decades, vaccines have saved countless lives and helped eradicate some fatal diseases. The push to do away with vaccines will not only endanger our youth, but our society as a whole. Vaccination is needed to maintain a healthy balance within our country. Vaccines provide the immunity that comes from a natural infection without the consequences of a natural infection. Vaccinations save an ever-growing amount of lives every year. The Center for 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 (“Vaccine ProCon”).
