In role of a vaccine is to bring that

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 fight 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.1
“The Centers for Disease Control and
Prevention (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.”2 Those cases
of illnesses that evaluated from Centers of Diseases Control and Prevention clearly shown how the
effectiveness of vaccines helped to prevent the children’s health saved them
from death. 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, World Health Organization estimates that in 2003, 38.3 million
cases and 607 000 deaths were prevented by the use of pertussis vaccination”3.”However, pertussis
is still estimated to cause 295 000– 390 000 childhood deaths annually, with
most deaths in countries with low immunization rates and also in high mortality
rates but few of it. 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.”4 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.5 “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.”6After
the investigation, the result wasn’t getting any positive connection with
thimerosal that affected the function of brain or parts of the body, verbal memory,
behavior, regulation of 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.7

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 United 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.8 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. Giving more examples of the benefit of herd immunity, many medical experts demonstrates the percentage
between 92% and 95% of children should obtain approximately two doses of the
measles, mumps, and rubella which is MMR. The necessity of the measles, mumps,
and rubella vaccine is to control the infection and manage the number of
vaccinated people in order to sustain the herd immunity. Because most
individuals already have the immunity in their bodies, so the herd immunity can
provide them more by increasing the uprising in good standing to fight against
the disease. “Indeed, even a highly infectious disease like measles simply
cannot spread when herd immunity has been achieved.”9 Moreover, another case shows what happened in England when MMR (measles,
mumps, and rubella) vaccination rates dropped. Measles is a kind of disease
that has extremely infectious in which it caused a higher group resistance
limit than most different illnesses. “In the late 1990s, measles, mumps, and
rubella vaccine rates began to drop from more than 90% to 80% or lower—well
below the level required for herd immunity against measles. In response, the
number of cases began to rise: while only 56 cases were confirmed in Wales and
England in 1998, 1,348 were confirmed by 2008. A disease whose spread in the
country had been halted more than a decade prior was once again endemic.”10

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 Centers
for Diseases Control and Prevention 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.”11 In many countries such as Afghanistan,
Nigeria, and Pakistan, they didn’t have the opportunities to fulfill
vaccination programs to people in which can cause the level of infection
diseases rising up. Because there is no prevention from the vaccine in which
really needed for each individuals health around worldwide countries.

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.”12
“For each 1% increase in vaccination rate, 680 additional children were
diagnosed with autism or speech delay.”13
“Similarly, the rate of autism in Sweden also appears to have begun to
increase in the mid to late 1980s and, in fact, may have started much earlier.

Population-based data representative of the city of Gothenburg (Sweden’s
second-largest city) shows an earlier increase in the prevalence of autism and
autism-like conditions from 4.0/10,000 children in 1980, to 7.5/10,000 in 1984,
to 11.6/10,000 in 1988.”14Those sources
are recorded by various of studies which prove that the ingredients of vaccines
are 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 in their structure and function. Therefore, the
patients can be faced with many severe symptoms such as Alzheimer’s disease in
old people, Parkinson’s disease, etc. Moreover, vaccines are not necessary
because the diseases of vaccines target have essentially disappeared.

“According to the Centers of Diseases and Prevention 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.”15
Due to those reported, people claiming that all the target diseases are
becoming declined, so they don’t think vaccines are needed for prevention health
or improve immunity anymore.

Nevertheless, vaccines
have some spots of effects but the overall picture of this prevention method is
positive usefulness, and nonstop uprising its advantages. If there are
no vaccines, how many epidemics and dirt around the surrounding environment
will affect people’s health, vaccines as a tool for the immune system to
prevent the disease to ensure the health of individuals in particular and a
community in general. 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.
