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
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.
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.” 
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.
