  Abstract 

Background: Health professionals are cited as the most trusted source for vaccine information, even among the unvaccinated. Research suggests that health professional educational programs lack training and education related to vaccine safety and addressing vaccine-hesitant patients and caregivers. Education for health professional students has been shown to impact knowledge, individual hesitancy, and confidence in ability to address patient vaccine hesitancy. Methods: A virtual educational program was developed and delivered to pharmacy, nursing, and medical students to impact vaccine-related knowledge, hesitant attitudes, and confidence in addressing vaccine-related topics with patients and caregivers. A survey was delivered before and after the training to identify the educational impact. Results: In total, 8 nursing programs, 1 school of pharmacy, and 1 medical school participated in the program. There was a significant (P < 0.05) increase in confidence and knowledge for pharmacy, nursing, and medical students. There was a significant (P < 0.05) decrease in vaccine-hesitant attitudes among nursing students. Overall satisfaction with the program was high, with 92% of students stating they would recommend the virtual educational program. Conclusions: A virtual education program designed for multiple health professional disciplines increased student knowledge, decreased individual hesitancy, and increased confidence in their ability to address patient vaccine hesitancy.

  Introduction Top


Vaccines are considered one of the major public health achievements of the last century.[1] Vaccination not only prevents a vast number of illnesses and hospitalizations but also prevents 2–3 million deaths a year associated with vaccine-preventable diseases.[2],[3] However, vaccine hesitancy threatens those achievements both within the United States and globally.[4] Even before coronavirus disease 2019 (COVID-19), the World Health Organization (WHO) recognized vaccine hesitancy as one of the leading threats to global health.[2]

On March 11, 2020, the WHO declared COVID-19 as a pandemic.[5] COVID-19 has caused millions of illnesses, hospitalizations, and deaths globally. The United States has access to multiple COVID-19 vaccines that are rigorously tested, highly effective, and safe.[6],[7] As of July 2021, COVID-19 vaccination has saved an estimated 279,000 lives and prevented 1.25 million hospitalizations in the United States.[7] Yet, COVID-19 vaccination rates remain suboptimal, and overall routine immunization rates have declined in the United States during the pandemic.[8],[9],[10] Concerns on vaccine safety and efficacy are often cited as reasons why individuals will not receive a COVID-19 vaccine and/or other commonly recommended vaccines.[10],[11],[12]

The reasons why individuals choose not to vaccinate are complex. Research has shown that perceptions of trustworthiness related to health information can significantly impact health behaviors.[13] Health professionals are often cited as the most trusted source of vaccine information and play a fundamental and direct role in promoting vaccination.[4],[10],[13-16] Additionally, health professionals with greater knowledge on vaccines are more likely to engage in dialogue with patients on the topic of vaccinations and make a strong vaccine recommendation. Such behavior can increase vaccine confidence and acceptance.[17],[18],[19]

Research has shown that future and currently practicing health professionals are unprepared to address patient-related questions and concerns regarding vaccines. This can be contributed to lack of knowledge on the topic, confidence in their individual abilities, and strategies to address the vaccine conversation, all of which may lead to an absence of vaccine recommendation to patients and their caregivers.[20],[21],[22],[23],[24] Health professional training programs have noted that students could benefit from additional education related to risks and benefits of vaccination, vaccine safety, and how to address vaccine hesitancy.[16],[20],[22],[25-30]

Education and training can equip future health professionals with strategies and tools to address vaccine-hesitant patients and caregivers.[31] Once a health professional has an established practice, it is challenging to change their behaviors. Thus, students are an important target for education on this topic as they are still developing their skills and are open to changing their habits.[32],[33] There is a paucity of data exploring the training and education health professionals receive regarding vaccination and addressing hesitancy. What studies have been conducted suggest that training related to vaccination can improve students’ knowledge and confidence in addressing vaccine hesitancy.[18],[21],[23],[24],[34] However, most of these studies have primarily targeted medical students, and little has been done to address other disciplines that may also have a significant impact on patients’ perceptions of vaccine safety and necessity.[18],[31],[34] Pharmacists are increasingly acting as vaccine providers, and nurses are often the first health professionals patients may interact with during the medical encounter.[35],[36] More research is needed on the impact of educational programs designed to address all health professional students’ vaccine-related knowledge, confidence in discussing various topics related to vaccine administration, and hesitancy.


  Methods Top


The objective of this study was to assess the impact of a virtual education program on health professional students’ vaccine-related knowledge, vaccine-hesitant attitudes, and confidence in addressing vaccine-related topics with patients and caregivers. Additionally, the education sought to provide students with tools and strategies for conversations with vaccine-hesitant parents and caregivers.

This educational intervention was conducted with health professional students in higher education institutions in the state of North Dakota. All institutions that housed nursing, pharmacy, or medical programs in the state were invited to participate in the virtual educational program offered by the North Dakota State University Center for Immunization Research and Education (NDSU CIRE). The study was approved by the NDSU Institutional Review Board (IRB), and all participants provided their informed consent before participating in the research. The hypothesis of this cohort study was virtual education program would increase student knowledge on, decrease hesitant attitudes about, and increase confidence discussing vaccine-related topics.

Educational intervention

The virtual education was developed by the NDSU CIRE for staff, who have extensive expertise in vaccine safety and efficacy and tools to address vaccine hesitancy. Topics were selected based on previous research conducted within the state to determine what vaccine-related topics and themes should be addressed in the curriculum.[23] The intervention was designed in accordance with previous research in the field, specifically addressing what is desired for health professional vaccine education.[22],[23]

The education had three main objectives. The first objective was to increase vaccine knowledge, specifically knowledge related to vaccine development, licensure, and safety monitoring processes. The second objective was to address students’ vaccine-hesitant attitudes. The third objective was to increase students’ confidence in addressing vaccine-hesitant messages. Two unique communication strategies were introduced to students to address patients’ and caregivers’ vaccine-related questions and concerns. The designed three-hour education included lecture content, case studies, role-playing, discussions, and question and answer sessions. In addition, the authors provided supplemental resources addressing communication strategies (C.A.S.E. Approach and Motivational Interviewing), immunization schedules, and interactive course notes.[37]

At the beginning of the 2020–2021 academic year, all health professional programs across the state of North Dakota were contacted and invited to participate in the virtual education. This included 14 nursing programs, 1 medical school, and 1 school of pharmacy. Health professional program participation was completely voluntary and free of charge to participants. The educational offering was developed and provided from a grant from the North Dakota Department of Health. Programs were contacted through an email invitation, and interested health professional programs coordinated with the NDSU CIRE team to choose dates and times that worked within their schedules. All education was delivered between the fall of 2020 and the spring of 2021.

Survey development

To measure the impact of the virtual educational intervention, a survey was developed and distributed before and after the virtual education was given. The survey included questions to assess students’ knowledge (12 questions), individual hesitant attitudes (11 questions), and confidence in addressing patients’ and caregivers’ vaccine-related questions (9 questions). Survey questions were designed from previously published and validated tools.[22],[28],[37-39] The survey is available from authors upon request.

Before completion of the educational program, the pre-survey was distributed to the participating health professional students. Students were asked to create a unique identifier to track students’ survey responses pre- and post-training. Initial pre-survey questions collected demographic information, such as students’ age, gender, health professional program, and associated year, along with questions assessing students’ perceptions on how well their health professional programs addressed vaccine-related topics within their curriculum (5 questions).

Immediately following the virtual education, students were asked to complete a post-survey using the same unique identifier used in the pre-survey. Post-survey questions used the same questions as the pre-survey in addition to questions seeking students’ opinions and feedback on the value and benefit of the virtual education. Although completion of the surveys was highly encouraged, it was not a requirement.

Descriptive statistics were used to evaluate questions related to students’ assessment of their program’s vaccine-related education and their general satisfaction with the NDSU CIRE virtual education. These data were presented in the form of percent agreement. The overall data set was reduced to those with pre-post–matched responses to measure the programmatic and individual change in knowledge, hesitant attitudes, and confidence in addressing patients’ and caregivers’ vaccine-related questions. Hesitancy and confidence questions were assigned scores between 1 to 5 based on the Likert scale (strongly disagree = 1 to strongly agree = 5) for each category to take the mean score for each question. Knowledge questions were assessed based on the number of questions answered correctly. A paired t-test was used to determine the mean change values between pre- and post-intervention mean scores. Statistical significance was determined with a P-value < 0.05.


  Results Top


Throughout the 2020–2021 academic year, 8 out of the 14 state nursing programs and both the medical school and school of pharmacy agreed to participate in the virtual education. From those programs, 178 pharmacy students, 137 medical students, and 247 nursing students completed the pre-survey, representing 100%, 97%, and 84% of each health professional group, respectively. Of those, 76.6% were in the age group between 18–24 years, 72% of participants were female, and 26.5% were male.

Overall, participants perceived their respective health professional programs were providing adequate training related to vaccines [Table 1]. Students across all health professional programs acknowledged gaps in their vaccine curriculum, most notably training on the vaccine testing and approval process and how to communicate with vaccine-hesitant patients/caregivers.

In total, 26 medical students (18%), 63 pharmacy students (34%), and 152 nursing students (52%) had paired pre/post-survey responses to measure changes in confidence, individual hesitancy, and knowledge before and after delivery of the educational intervention [Table 2]. There was a significant increase (P < 0.05) in confidence and knowledge for each health professional student group. There was a significant decrease (P < 0.05) in vaccine-hesitant attitudes with nursing students, but there was no significant change among medical and pharmacy students. The greatest overall change in all three categories was seen with the nursing students.

When further analyzing each category by the question, it was apparent that pharmacy students and medical students already had low vaccine hesitancy [Table 3]. Therefore, there was not as much growth within most topics for these disciplines on this topic. However, students from all three professional programs showed significant growth in agreement that their strong recommendation for a vaccination will impact a patient’s decision on whether or not to vaccinate.

All health professional programs had significant growth when comparing pre- and post-training knowledge scores. High scores reflected greater vaccine-related knowledge. Pharmacy students had the highest mean scores both pre- and post-training, followed by medical and lastly nursing student scores [Figure 1]. When assessing specific knowledge-related questions by health professional program, all three student groups showed significant growth in two questions assessing students’ understanding of the hierarchy of evidence. These questions assessed students’ ability to interpret data and understand the vaccine development and regulatory process related to the COVID-19 vaccine. Both pharmacy and nursing students had significant growth in a question assessing data and causal relationships when interpreting a fictional case related to intussusception and the rotavirus vaccine.

Overall satisfaction with the program was high, with 92% of respondents stating they would recommend the education they received to other health professional programs. Similarly, 92% of post-survey respondents stated that they intended to use the communications strategies learned in the virtual education to address vaccine-hesitant patients and caregivers in the future as health professionals.


  Discussion Top


The objective of this study was to assess the impact of a virtual education program on health professional students’ vaccine-related knowledge, vaccine-hesitant attitudes, and confidence in addressing vaccine-related topics with patients and caregivers. Overall, all three health professional programs showed statistically significant growth in knowledge and confidence. This is important as health professionals are often cited as the most trusted source of vaccine information.[10],[13],[16],[40] Our study found similar results to other health professional vaccine education programs in relation to the growth in knowledge.[23],[31],[34]

Pharmacy and medical students did not see a statically significant decrease in hesitant attitudes. Yet, when looking at the individual questions, it was apparent that they already had low vaccine hesitancy. Although there was not a statistically significant change in vaccine hesitancy within these two groups, all three health student groups showed a statistically significant change in believing their strong recommendation for a vaccination will impact a patient’s decision on whether or not to vaccinate. This is noteworthy because health professional students who recognize the influence of their recommendation increase patient vaccine confidence and acceptance.[17],[18]

There was also a significant growth in knowledge among all three health professional student disciplines. Knowledge-based questions assessed basic principles of immunizations and interpreting research. It is critical that physicians, pharmacists, and nurses have the skills and knowledge to address patients’ vaccine-related questions. In addition, a health professional’s vaccine awareness and knowledge has been shown to be directly related to their willingness to recommend vaccination.[20] Although there was a significant gain in knowledge for all three health professional groups when comparing pre- and post-training scores, when assessing solely post-training scores, none gained an overall percentage correct over 70%, a standard benchmark. This was mainly because there were a few questions that decreased the total average, specifically knowledge questions that required more clinical reasoning. The authors recognize that this finding needs to be further investigated.

Overall, before the educational intervention, health professional students felt their program adequately covered topics on vaccine-preventable disease, how vaccines work, and the safety of vaccines. Only 66% of students stated they were adequately trained on how to communicate with vaccine-hesitant patients/caregivers, and only 62% felt they were adequately educated on the vaccine approval process. This highlights a need for more education on these topics for future health professionals. Because we did not ask the participants about their perceptions of vaccine-related education after the education intervention, we are unable to determine if the information provide caused a change in perception.

Overall, participating students showed strong satisfaction with the virtual education. Providing the education virtually saved time and resources that would be devoted to travel and in-person delivery. In addition, statistically significant changes were seen within all health professional student groups, although the entire education was presented and experienced virtually. This could be considered for future institutions that integrate multiple health professional disciplines, for institutions could integrate education with multiple disciplines simultaneously.

There were some limitations to our study. First, our study took place within only one state in the United States. In addition, we were only able to study one pharmacy and medical program. Although we provided our education to a significant number of health professional students, limited matched pre/post-surveys caused a decrease in sample size, and we did not provide a control group. Finally, we are unable to determine if our educational intervention will have long-term effects and influence future patient/health professional relationships. Future research is needed on the long-term effects of vaccine educational programs.


  Conclusion Top


The development of a virtual educational program allowed the ability to provide education to multiple programs and multiple disciplines. In addition, each program showed a statistically significant change, which could lead to a strong vaccine recommendation in the future.
