Assessment 1: Research Methodologies and Immunization (NURS 3044, SP4)

This assignment, designed for a nursing course (NURS 3044), focuses on research methodologies related to immunization. The student, acting as a registered nurse, is tasked with addressing parental concerns about vaccinations. The assignment begins with background information on the anti-vaccine movement and prompts the student to develop a researchable question, identify sources of evidence, and formulate search terms to find relevant literature. The student is required to analyze four articles, completing a table with information on search strategies, inclusion/exclusion criteria, study issues, contexts, and outcomes. This involves evaluating studies on vaccine safety, including meta-analyses, systematic reviews, and experimental quantitative studies. The overall goal is to equip the student with the skills to critically evaluate research and provide evidence-based information to address parental concerns about immunization, promoting public health.

Assessment 1
Instructions:
 Please read the background information below. When you have read the background
information, you can proceed to the questions on the Assessment Template. These
questions relate to the background information.
 You will need to apply the knowledge that you have gained from Topics 1-4 to complete
these questions.
 The marks allocated to each question are stated next to the question.
 The word count is stated next to each question. Note that when the word count says
‘equivalent’ it means that you do not need to have that exact number of words to answer
the question – just provide as much detail as required to answer the question.
 You are advised to frequently refer to the Assessment Feedback Sheet to guide you on
what characteristics of a reponse constitute an F2, F1, P2, P1, C, D, and HD grade.
 As with all academic work, if you refer to the work of others to support your responses,
you must reference this information using the UniSA Harvard Reference System. You do
not need to reference the articles listed in the Tables in Question 2, but if any other
sources are used, these should be referenced.
Background: Immunisation – Health beliefs
You are working as a registered nurse in a GP Practice and one of your roles is to promote
immunisation for children (this may be the MMR or other recommended immunisations).
You have had a few parents refuse vaccinations for their children and this concerns you as
you believe that this may leave the child and communities vulnerable to outbreaks of serious
diseases.
You do not think that parents would deliberately expose their children to the risk of serious
disease unless they were guided by a belief that immunisation was not safe. You are vaguely
aware via media reports that there is an anti-vaccine movement, and you want a quick
overview of what it is all about. As most of us would do, you consult Google, and you find
the following information. Read the information video below:
The History of Vaccines: History of the anti-vaccination movement
The College of Physicians of Philadelphia (2017)
<https://www.historyofvaccines.org/content/articles/history-anti-vaccination-
movements>
You could now choose the following actions:
 Conclude that parents are entitled to make decisions about their child’s healthcare,
even if it is against public health policy.
| P a g e 1

 You could question your own belief system – after all, you are basing your practice on
government guidelines and you trust that the government will make decisions about
health care that are evidence-based, informed by experts in the field, and in the best
interests of Australians. You haven’t checked the literature for evidence of
immunisation safety yourself.
 You could investigate whether there is any evidence of harm caused by immunisation,
and to identify information that may influence parent’s beliefs or fears about
immunisation.
Naturally, you are a great nurse with an inquiring mind. You want to be certain that there is
good evidence that demonstrates that immunisations are safe for children. You want to
understand what information has led parents to be concerned about immunisation. Finally,
you want to be able to have an informed discussion with the parents about their concerns
based on current evidence to help them make the right decision for their children.
Question 1 (20 marks) (400 word equivalent)
Question 1A
| P a g e 2

After reading the background information, develop a researchable question from the
background information that you have been given relating to immunisation. This question can
be suited to quantitative or qualitative methods. Type your question below:
Is the recommended vaccines compulsive used to children are safe to the children
immunization programs?
P: children
I: use of vaccine
C: recommended vaccines compulsive or voluntary
O: safe to the children immunization programs
Question 1B: List three sources of information that would provide you with the best
(strongest) evidence that would enable you to answer your research question. For each of
the three sources, give an example of the type of information that would be available to you
from this source.
*The examples provided below represent a source of information and a type of information
available from that source. It is not suggested that these are the best sources of evidence.
Source of information Type of information
The NCBI website The website would give studies in form of clinical
trials concerning the use of vaccines in health
The NIH website This would provide the recommended level of
safety in the use of vaccines in children
World Health organization, department of
vaccines, immunizations and biological
A guide on conducting an expanded programme on
immunizations (EPI) review
Question 1C: List five search terms that would assist you to find suitable literature to answer
your question. For each of the search terms, suggest an alternate word for which the Boolean
function “or” could be used.
Keyword Search term for Boolean ‘or”
1 Vaccination or immunization
2 Safety or efficacy
3 Health or wellbeing
4 Side effects or adverse reactions
| P a g e 3

5 Evaluate or determine
Question 1D: If your search failed to find a satisfactory number of quality articles, outline
the actions that you could take to improve your search results.
If no enough number of article about this subject can be found, then a number of strategies
will be adopted to ensure that as many materials as possible are found. The strategies to
increase the number of search results are by searching multiple databases, likes library
websites and health databases to search for articles, to modify the keyword and question, or
to break down the research questions into PICO/PIO elements and work out the concepts for
each PICO/PIO elements. To develop the search strategies by vary the expression or
keywords for each concept with the use of abbreviation , tuncation , wildcard and phrase
searching and so on. Turncation identifies different variations of a word. Using truncation
will broaden the search. Frequently used truncation symbols include the asterisk (*), or a
question mark(?) . For example, to search the word “nurse”, use truncation nurs* will
broaden the search. The wildcard will help to spell the identical word in different ways which
is to obtain different spelling of the same word. Another method is to use the quotation marks
when referring to certain exact phrases in a search sentence. Once the quotation marks are
added to a search phrase, the returned results are specific to the words used, thus limiting the
number of returned search pages. Often uses a ? as a wildcard symbol. For example:
randomi?ation can found in the research articles in two different spellings: Randomisation
and Randomization. The method phrase searching is to examine two or more words as an
exact phrase. Phrase searching includes double quotation marks (“ ”) around two or more
words to create a search term. For instance: “genetic engineering” will search for results
includes the word “ genetic” and “engineering” will appear next to each other. Additionally,
apply Boolean operators correctly such as: and, or, not, to expand or narrow the search
depending on the search terms. Use thesaurus to find out more suitable search terms. Use
keywords more focused on the research question. Moreover, the advanced option can be
clicked on the browser so as to refine the results based on country, date, language, year of
publication article typing and much more information as may be required.

Inclusion/exclusion
criteria
The included studies in this research were those involving case controls and cohort studies concerning the possible link
between autism and vaccinations. Additionally, only information from databases such as PubMed, EMBASE, Google
Scholar and MEDLINE, published up to April 2014 were considered for this research. Therefore the included materials
were five cohort studies that had 1,256,407 children, and another five case-controls that had 9,920 children. Any other
studies that never met the above criteria was excluded from the study.
Issue (what was being
studied)
The research was studying the argument that the vaccines are not associated with development of autism.
Context (study setting) This study involved database searches by use of controls and cohort studies involving the possible link between the use of
vaccines and development of either autism or autism spectrum disorders (Taylor et al., 2014). There were two reviewers
who extracted the available data concerning the study features, methods used and the results found. In case of possible
disagreements, they were resolved by a way of consensus with a different author.
Outcome (main findings) This article found out that there was no any relationship between vaccination and autism and autism spectrum disorders
(Offit, 2013). Additionally, there was no relationship between autism and MMR or thimerosal, a compound used in the
preservation of vaccines. For the case control data, there was no relationship found between increased risk of autism or
autism spectrum development disorder upon use of mercury, MMR or thimerosal by either grouped condition or grouped
exposure. Thus the components of vaccines, i.e. the mercury and thimerosal, as well as multiple vaccines are not linked to
the development of autism or autism spectrum disorder.

Inclusion/exclusion
criteria
The studies included in this research were those of either comparative prospective or retrospective nature, among healthy
people, and aged exactly 15 years. Additionally, these studies were required to have been either carried out or conducted in
2003.
Issue (what was being
studied)
The aim of this research was to determine the events of following immunization with MMR, through a systematic review.
This is following several debates concerning the safety of this trivalent vaccine and the continued drop in the vaccination
rate in various countries (Jefferson et al., 2003).
Context (study setting) The study setting involved the carrying out of a systematic review to determine whether there is evidence of unintended
side effects either good or bad, when people receive the MMR vaccine. Moreover, this study assessed whether systematic
review methods can be applicable in evaluating safety aspects. While about 120 studies were found to satisfy the study
criteria, only 22 of them were used for this study.
Outcome (main findings) This study found out that the MMR vaccines are associated with the upper respiratory tract infections, irritations, and
possible development of benign thrombocytopenic purpura, joint pain and aseptic meningitis, as compared to the placebo.
Additionally, it was found that the use of MMR vaccine is not likely to be associated with the Crohn disease, autism,
aseptic meningitis and ulcerative colitis. The use of systemic reviews in reporting of safety outcomes about MMR vaccines
was not found to be adequate enough.

Population (how many
participants, age, gender,
disease, etc)
This research involved healthy children aged between two to twenty two months, who were to receive two types of doses
of either the MMRV or MMR dose, at 42 days apart (Prymula et al., 2014). However, this study involved 5,803 children
but the gender composition of the sample is not given. The children used as the study sample, were healthy initially, but in
this case they were admninsteres one dose of varicella, or two doses of MMRV vaccines respectively, to determine the
possibility of protection against varicella.
Intervention (what was
being implemented)
The administration of either a single dose of varicella vaccine, or two doses of MMRV vaccine.
Comparison (was the
intervention being
compared to another
strategy, e.g. placebo?)
Yes, the use of comparison was done, whereby the cintervention group received either two doses of MMRV, or MMR and
varicella vaccine, while the control group received two doses of MMR. This was done for the comparison of the results.
Outcome (main findings) There were 37 confirmed cases of varicella among the MMR group. The findings of this research supports the use of two
doses if varicella vaccine on a short course, so as to ensure that there is optimum protection from any form of varicella
disease. In the MMR and Varicella vaccine group, there were 243 cases, while in the MMRV group, there were 201 cases.

This study involved seventeen questionnaire administered among parents in the UK. The age and gender information
about the participants is not provided in this article. However, the research aimed at determining the scare resulting from
the measles, mumps and rubella vaccination, and its impact on the parents of children (Guillaume and Bath, 2004).
Issue (what was being
studied)
It was aimed at studying whether the MMR vaccine caused any scare among the parents of young children, and whether
there was effects to the need for additional information about the same.
Context (study setting) This study was conducted as a result of increased cases, of mass media reports on the panic arising from health issues and
interventions, because those involved need information.
Outcome (main findings) It was found that the health scares increased the need for more information by the parents of the young children in terms of
making decisions on whether their children would be determined or not. In this case, the parents did not value the
traditional information about MMR vaccinations since they were not viewed to be trust worthy (Yang, 2014).

Question 3 – 800 words
 Discuss the reasons that the studies above would or would not be helpful in enabling
you to have an informed discussion with parents about immunisation for their
children. Comment on the relative value of the studies to your argument. Use
supporting evidence where appropriate.
Since the history of vaccines, and vaccinations, there have been controversies
concerning its efficacy and safety. Most of the issues raised against the vaccinations is
concerning the side effects as well as the ethics part of it. There are some vaccines
like the MMR which have been reported to have some serious side effects (Jain et al.,
2016). However, there are several research studies conducted to confirm this, but no
agreeable results are given. In other case, the parents based on various beliefs and
religion beliefs argue that the manner in which the vaccines are developed and
administered is not within their religious traditions. As a result of this, there have been
ongoing debates on whether to use vaccines or not. On the other hand, the
governments in various countries have put strict regulations and policies concerning
the need for the parents to have their children vaccinated, bearing in mind the disease
outbreaks which are quite difficult and expensive to treat (Taylor et al., 2015).
Therefore, generally, vaccination is an important program in public health. According
to the governments, the issue of vaccination decision is not a decision that the parents
or the families can make for themselves. Based on clinical evidence, the vaccines are
important and work in two major ways: first is that they decrease the risk of
contracting a disease, and second, they lower the number of potential carriers of a
disease in a population, and hence improved health outcomes. Therefore, the ore the
number of vaccinated people, the more difficult it is, for a disease to spread (Uno et
al., 2015). For the case, of children, vaccination confers herd immunity among
children, especially for those who are too weak or too young to be vaccinated. But the
question really is, what makes people to get scared about immunizations?
It is true that the people with a weakened immune system are not fit to get vaccines
like measles, mumps and rubella, because such people can possibly end up with
inflammation in the brain, encephalitis and in other cases, they can die. However, the
parents need to understand that these side-effects, even though they might occur, they
are quite rare (Horne et al., 2015). Furthermore, if people are infected, say with
measles, this condition can cause its own risks of other cases like encephalitis. Even
| P a g e 10

though there are some negative side effects associated with the use of vaccines, the
benefits are much more. These studies discussed above could be quite helpful to me in
making informed decisions concerning the parent’s anti-vaccination ideologies (Gale,
2017). For instance, the study by Taylor et al., 2014, is clear enough in the
establishment of the possible thought link between vaccinations and the development
of autism or autism spectrum disease (Foster and Ortiz, 2016). After the consideration
of a number of literature, this author finds that there is no relationship between the
MMR vaccine and the development of autism or autism spectrum disorders (Jain et
al., 2015). Since this study was carried out using proper design and methodologies,
then the findings are clear enough to convince me that truly, the vaccines are and
immunization programs are safe and effective.
However, the study by Jefferson et al., 2003, reports that the use of the MMR vaccines is
likely to cause some side effects such as the upper respiratory tract infections. All in all,
although some of the said side effects are true, the benefits are truly so much more.
Additionally, according to the risks, the parents in the article by Guillaume and Bath, 2004,
report that such anti-vaccination scares are important because they keep the parents of the
young children who need to be vaccinated, aware of the recent information concerning the
use of vaccines, and therefore avoid, old literature materials which could be unreliable.
The history of compulsory vaccinations against small pox repeats the situation that is
happening concerning the current vaccination controversies (Yaqub et al., 2014). At the
moment, the vaccination debate is associated with some crucial questions concerning the
government policies making vaccinations compulsory. If one fears that their children might
get contaminations with vaccination, or the method of vaccination, for instance the one on
small pox was associated with the vaccination material. For instance, in the United States, the
small pox vaccine helped many people to reduce the risks of small pox which many years ago
was a deadly disease (Yale, 2014). However, the method of vaccination, especially by public
health officials was deemed unsanitary and quite unsafe especially to the people of low
social-economic status, due to the arm-to arm administration method. The policy of
vaccination being a compulsory undertaking by all citizens is in the process of the
government acting in common good for the people’s health (Peretti-Watel et al., 2013).
Despite the continued objections towards the issue of vaccinations, the health practice been
important in preventing the spread of many diseases. Although they are not risk-free, they are
| P a g e 11

a bit safer than any other treatment methods. Considering the risk of some diseases like
tuberculosis and some viral infections, the use of vaccines, is the best prevention method.
