Abstract
The study is dedicated to the coverage of the peculiarities of
the organization of the vaccination campaign against COVID-19
in Ukraine, all this, to analyze the achievements and current
problems of the outreach work of medical institutions of higher
education. This paper is an independent scientic research review with an
analysis of the questionnaire data on the problematic issue. The study was
based on the application of a series of theoretical and empirical methods:
analysis, systematization and generalization of data on the search for
the characteristics of the organization of dissemination work in higher
medical education institutions; questionnaire survey to the participants
of the educational process.The survey involved 250 respondents from
the aforementioned medical HEIs. The results established the awareness
of the participants and also testied to the feasibility and importance of
strengthening outreach activities in the selected higher medical education
institutions. We conclude that consistent disclosure about the risks,
uncertainties and availability of vaccines fosters public condence in
vaccination.

Introduction
Vaccination is one of the safest and most eective methods of protection
against many infectious diseases. According to World Health Organization
(WHO) experts, increasing global awareness of the importance of
vaccination can save a signicant number of lives. The COVID-19 pandemic
has repeatedly increased the importance of immunization for both
individual and collective protection (Chertakova et al., 2020).
788

Vaccination campaign against COVID-19 in Ukraine: Current Problems of State Educational Policy and
Outreach Work of Higher Medical Educational Institutions
In recent years, however, there has been a decline in the rate of
immunization worldwide. This is why the vaccine campaign against
Covid-19 has faced several challenges. To date, domestic and foreign
medical scientists have noted that mistrust of vaccination has hindered
the expansion of immunization coverage and have suggested strategies to
address this problem.
The concept of “mistrust of vaccination” has entered medical practice
(Yakovenko, 2020: 72–77), which has been dened as situations where
people either delay or refuse immunization despite the availability of
services. The problem is complex and context-specic. Its nature may
vary according to time, place, and specic vaccine type. Factors such as
indecision, uncertainty about the vaccine, irresponsibility, and mistrust
can have an impact. In addition, the most important factor in refusal to
immunize can be considered a lack of public awareness of the importance
of vaccination in the ght against COVID-19 (Zakharchenko, et al., 2022).
As the experience with COVID-19 has shown (Syamila et al., 2021), all
structures of the state must cooperate in the ght against infectious diseases.
A special place in outreach belongs to medical institutions: institutions of
medical care as well as institutions of higher medical education, which
are called upon to actively inform the population about the benets of
vaccination and the risks associated with refusal to vaccinate. And the best
way to address the problem of vaccine hesitancy is through awareness-
raising activities that are democratic and based on full respect for human
rights (Pidyukov et al., 2021).
Consequently, the purpose of the article is determined by highlighting
the peculiarities of the organization of the vaccination campaign against
COVID-19 in Ukraine and analysis of modern achievements and problems
of awareness-raising work of medical institutions of higher education.
1. Material and methods
The above goals and objectives of the study determine the use of such
theoretical and empirical methods as: analysis, systematization, and
synthesis of data to identify the features of the organization of outreach work
in institutions of higher medical education; questioning the participants of
the educational process to identify the level of awareness of the peculiarities
of the organization of vaccination campaigns.
The study was conducted during 2021 at the Department of Linguistics
of the Faculty of Foreign Citizenship Training of the Ivano-Frankivsk
National Medical University and the Department of Faculty Therapy of
the Faculty of Medicine of the Uzhhorod National Medical University. The
789
CUESTIONES POLÍTICAS
Vol. 40 Nº 73 (2022): 786-797
study involved 250 respondents of these medical HEIs. A number of works
by leading domestic and foreign scientists have been devoted to the study
of the phenomenon of population vaccination (Kozlovskyi et al., 2021),
which analyzed the fundamental principles of this process (Kaliuzhnaia et
al., 2018), noted the feasibility of using mass vaccination when spreading
infectious diseases in education (Orenstein and Ahmed, 2017); emphasized
the importance of educational work among the population on the importance
of mass vaccination (Mollarasouli et al., 2022).
However, these diverse studies did not cover all aspects of the functioning
of vaccination campaigns, and the factual data obtained from numerous
questionnaires concerned mainly subjective public opinion, skepticism
about the role of information resources in health issues, lack of necessary
knowledge about vaccination, etc. Thus, the scientic novelty of the article
lies in a multifaceted and at the same time comprehensive and holistic
consideration of the role of outreach activities of medical HEIs during the
vaccination campaign against COVID-19.
2. Results
Conducting mass vaccination campaigns as part of prevention or in
response to disease outbreaks that have widespread consequences is one
eective measure to prevent the spread of disease and reduce mortality
rates. However, due to the need for physical distance to reduce the spread
of COVID-19, many countries have decided to postpone such campaigns.
Therefore, choosing the optimal strategy for outreach work in the countries
of the world and Ukraine, in particular, has experienced certain diculties.
The challenge during such work was to balance the benets of safe and
eective anti-epidemic measures against the risk of increasing the rate of
spread of the new infection, which could aect the system of basic health
care delivery. In considering this question, one must rst rely on a detailed
examination of epidemiological data (Supriyadi, 2021). In a prolonged
COVID-19 pandemic, providing the necessary knowledge to counteract
the spread of coronavirus disease is an essential element in the phase of
organizing a vaccination campaign. At the same time, even though the
topic of vaccination is relevant and topical, there is resistance from the
population.
Thus, the source of necessary, above all, reliable and scientically
sound information for the population should be a medical professional or
a medical educator. Since the implementation of the vaccination campaign
is based on the operation, dissemination, and recording of a signicant
amount of information, the place and role of employees of institutions of
higher medical education change signicantly - a great responsibility is
imposed.

Outreach Work of Higher Medical Educational Institutions
In addition to performing their professional duties, the scientic and
pedagogical sta of medical HEIs becomes not only a transmitter of certain
information, but also a source of information, trust, and persuasion.
By engaging in the organization of the vaccination campaign, scientic
and pedagogical employees of medical HEIs take on the responsibility
of informing the population about the vaccination process as a social
phenomenon, the involvement of resources, the choice of vaccine, possible
reactions, etc. Proper public awareness, data analysis, and monitoring
become essential for building a competent outreach eort on the need for
vaccination against COVID-19.
In this regard, the logical and quality organization of the databases
at all levels of the vaccination program requires signicant attention,
in particular, and with all the necessary requirements to protect the
condentiality and reliability of the information disseminated. Inaccurate,
falsied, or unveried information provided to the public could jeopardize
the implementation of the vaccine campaign as a whole and negatively
impact the process of establishing the evidence base for adult immunization.
Therefore, one should proceed with caution and consider all possible
risks (Mollarasouli et al., 2022). Errors and inaccuracies in outreach
work can lead to negative consequences. Hence, the development and
step-by-step implementation of reliable channels of communication and
information transfer between all participants of the process by medical
HEIs is of paramount importance.
According to the above, to organize a quality vaccination campaign
against COVID-19, outreach activities should be implemented in stages.
The main stages include the following (Remmel, 2021):
Conducting an assessment of the possible consequences of an
outbreak according to basic epidemiological criteria.
An analysis of the possible benets of a mass vaccination campaign
and an assessment of the country’s capacity to implement the
process safely and eectively (Iacobucci, 2021a).
Consideration of the possible risks associated with the intensied
spread of COVID-19 as a result of a mass vaccination campaign.
Selection of optimal algorithms of actions according to the epidemic
situation with the spread of COVID-19.
Analysis and consideration of best practices in Europe and the
world.
The step-by-step development of vaccination outreach activities
conrms the importance of the role of scientic and pedagogical employees
of medical HEIs in improving the eectiveness of the organization of the
791
CUESTIONES POLÍTICAS
Vol. 40 Nº 73 (2022): 786-797
vaccination campaign against COVID-19 (Iacobucci, 2021b), which is also
determined by their performance of certain functions (Fig.1).
Taking into account the new functions of scientic and pedagogical
employees of medical HEIs, it was decided to conduct a pilot study to nd
out the level of their inuence on society and the expediency and necessity
of outreach activities by them (Komykh and Nedria, 2022).
Before the start of COVID-19 vaccination outreach work, a questionnaire
survey was conducted among employees of several institutions of higher
medical education. A total of 250 respondents participated in the survey
and were asked several questions on their understanding of the importance
of COVID-19 vaccination.

Survey participants were asked to express their opinions on the criteria
of “very important,” “important enough,” and “not important.” So, the
results showed that 70 respondents considered COVID-19 vaccination
as very important and necessary, 120 as important enough, and 70 as
unimportant. These surveys are shown in the chart (Fig. 2).

Awareness of the importance and necessity of vaccination is complex
when all channels of receiving data on this process are involved. So, the
survey participants were asked a number of questions about awareness
of vaccination issues and their possession of certain information on this
issue. Respondents were asked to evaluate the level of satisfaction with the
informational work of the HEIs on vaccination, the level of awareness of
vaccination, and the level of suciency of the vaccination material.
The evaluation criteria were “very good”, “good enough” and “not good
enough”. So, the results of the survey were distributed as follows: very
good satisfaction with the information work of the HEIs was evaluated by
84 participants, fairly good by 114, and not good enough by 52. Very good
awareness of vaccination issues was evaluated by 71 respondents, good - by
124 and not good enough - by 55. 60 participants evaluated the materials on
vaccination issues as “excellent”, 118 participants as “good” and 72 as “not
good enough”. These surveys are shown in the chart (Fig.3).

The results of the surveys conducted revealed low awareness among
participants and showed the need to strengthen and improve outreach
eorts at selected medical higher education institutions.
More than 120 informational messages of thematic nature (types of
vaccines, positive eect of vaccination, consequences of refusal from
vaccination, etc.) were placed on the websites of selected medical HEAs,
more than 80 reminders about the benets of vaccination, formation, and
stability of immune protection developing after administration of various
types of vaccines against COVID-19 available in Ukraine were placed.
Presentations were organized by leading HEIs experts to promote
knowledge about the COVID-19 vaccine campaign. Data from selected
studies conducted around the world on post-vaccine immunity were
presented in an accessible form.
Roundtables, webinars, and meetings of scientic circles were held to
which dierent segments of the population were invited.
In addition, students from the named medical schools also joined
the work and actively participated in health education work among the
794

population on vaccination to improve knowledge and literacy of the
population about diseases, types of vaccines, complications in case of non-
vaccination, etc.
After a series of COVID-19 vaccination outreach activities, a follow-up
survey and questionnaire were administered to participants. The questions
on the questionnaires remained the same. The response parameters were
the same.
So, the results showed that after a series of COVID-19 vaccination
outreach activities, 100 respondents considered COVID-19 vaccination
very important and necessary, 130 respondents considered it important
enough, and 20 respondents considered it unimportant. These surveys are
shown in the chart (Fig. 4).

The results of the survey assessing the outstanding points of the
vaccination campaign were distributed as follows: very good satisfaction
with the information work of the HEIs was assessed by 101 participants,
“good enough” - 119 and “not good enough” - 30. Very good awareness of
vaccination issues was shown by 91 respondents, “good” - 29. The suciency
of vaccination materials was rated as “excellent” by 84 participants, as
“good” by 140, and as “insucient” by 26. These surveys are shown in the
chart (Fig. 5).

The results of the surveys found increased awareness among participants
and demonstrated the feasibility and importance of strengthening and
improving outreach eorts at selected institutions of higher medical
education.
3. Discussion
When analyzing the calligraphic aspects of the impact of vaccination
outreach measures, subjective aspects should not be excluded as well. It
should be noted that there is no universal strategy that could be an eective
mechanism and guarantee 100% readiness for vaccination. Subjective
factors include public mistrust of the vaccination process (Schaefer et al.,
2021). Distrust of vaccination may be a consequence of doubts about the
safety of vaccines, but it is only one of the underlying factors (Mahase,
2021).
A number of factors can lead to distrust of vaccination, such as: negative
beliefs based on myths, e.g., that vaccination leads to infertility in women;
misinformation; distrust of professionals or the health care system; the
inuence of authority gures, etc. (Mahase, 2019). The magnitude of the
problems and the specic conditions may be dierent, but they must be
taken into account when planning and implementing public awareness and
796

Outreach Work of Higher Medical Educational Institutions
vaccination activities. Therefore, it is essential to eectively develop and
establish channels of communication with the population.
Conclusion
The main barriers to developing a positive attitude toward the
vaccination process are fear of the risks of complications, dissatisfaction
with the quantity and quality of information about vaccinations, uncertainty
about vaccine eectiveness, and underestimation of the severity of the
possible course of the disease. Overcoming these barriers is one of the
most important professional tasks assigned to health care providers today.
Consistent, transparent, meaningful, and proactive outreach on risks,
uncertainties, and vaccine availability will build public trust in vaccination.
