Abstract
:Background: Training future healthcare professionals on vaccination through specific courses is important to properly promote active immunization among the general population and to fight fake news and false beliefs on vaccinations. The aim of the study was to assess the impact of an elective course about vaccinations on the knowledge of medical students, pharmacy students, and medical resident in Hygiene and Preventive Medicine in Italy. Methods: The participants were asked to complete an anonymous questionnaire before and after an elective teaching activity (ETA) on vaccination. The two questionnaires contained the same 30 questions and focused on different aspects of vaccines and vaccination. The students who had attended the seminar were allowed to fulfil the post-lecture questionnaire. Both descriptive and inferential analysis were performed on the results; in particular, Student’s t-test for independent samples was used to compare the total score obtained before and after attending the ETA. Results: A total of 449 students participated in the ETA. Overall, the participation in the ETA allowed them to significantly improve their final score (+27.28%, p < 0.001). Good results were obtained even when comparing the three groups (medical students, pharmacy students and medical residents) separately. Females improved more than males, especially among pharmacy students. Discussion: The present study highlights the importance and the impact that extracurricular activities can have in improving knowledge about vaccinations. With vaccination and vaccine hesitancy and acceptance topics with increasing attention paid by the population, especially after the COVID-19 pandemic, it is fundamental to develop new strategies to increase future healthcare professionals’ knowledge about vaccinations.
1. Introduction
Vaccination has been defined as one of the greatest medical discoveries ever made and its impact on health is comparable to the access to drinking water for the population. In fact, these two preventive interventions have been very successful in decreasing infectious diseases and their related complications and deaths [1,2]. This success was reached thanks to high level of immunization coverage and its maintenance over time.
However, in Italy, as in other European countries, the phenomenon of “vaccine hesitancy” is growing. “Vaccine hesitancy” means the distrust that a part of the population has towards vaccines and vaccinations [3,4]. In a recent survey, about 15% of Italian parents of children aged 16–36 months resulted hesitant and less than 1% fully contrary to vaccines [5].
To contrast the vaccine hesitancy, populations need to receive correct and comprehensible information: the main source of information on vaccines usually are healthcare workers, as general practitioners, nurses, healthcare assistants and pharmacists [6]. Therefore, it is crucial to train university students—the future healthcare professionals—on vaccination through specific courses [7].
Several studies explored the knowledge of healthcare students on vaccination or the impact of specific educational interventions [8,9]. In Italy, attempts at increasing the level of knowledge among students in healthcare area have been recently carried on, and remarkable results were reported [10,11].
The main aim of the study was to assess the impact of a training experience on vaccines and vaccinations involving students enrolled in the single-cycle degrees in Medicine and Surgery, in Pharmacy, and in the postgraduate school of Hygiene and Preventive Medicine of the University of Florence (Italy) during the COVID-19 pandemic period, when the attention of the general population to prevention activities and new vaccines was at peak. In particular, in that period the first COVID-19 vaccines began to be available on the Italian market and to be administered to priority groups.
2. Material and Methods
An Elective Teaching Activity (ETA) on vaccines and vaccinations was organized at University of Florence (Italy) in the period February–April 2021. The lessons were held during the COVID-19 pandemic period through online platform Webex and students filled in the questionnaires through the learning management system (LMS) called “Moodle”. Moodle is an open-source platform, where it is possible to deposit and consult educational material, to process questionnaires and tasks, to support exercises, to follow lessons in video-streaming, and to use collaborative work tools.
The course (16 h) included lessons on the different types of vaccines, preclinical and clinical trials, regulatory process, process of vaccine production, supply, and storage, dispensation of vaccines, Health Technology Assessment (HTA) of new vaccines or vaccination strategies, national immunization plan, immunization coverage, impact of current immunization strategies, pharmaco-vigilance on vaccines and, lastly, fake news and scientific evidence on vaccines. A relevant focus was dedicated to development and authorization of COVID-19 vaccines, their characteristics and safety profile. Students from the III to VI year of the Degree Course in Medicine and Surgery and students from the III to V year of the Degree Course in Pharmacy in the academic year 2020–2021 decided to voluntarily attend these extracurricular lectures about vaccinations. Moreover, medical residents of the Medical School of Specialization in Hygiene and Preventive Medicine (I and II year) of the University of Florence attended the lessons too.
To evaluate the impact of the training intervention on the knowledge of the students on vaccinations, each participant was asked to fill in the same questionnaire before and after attending the ETA. Only those who attended the ETA were allowed to complete the post-lecture questionnaire. Both questionnaires contained 30 multi-choice questions on the main topics of the teaching activity. Each correct answer was assigned a score of 1.07 points, for a total score of 32 points that corresponded to “30/30 cum laude” (passing grade 18 points). The passing grade for each topic was reached with two correct answers out of the three questions contained in the topic.
Filling in the questionnaires was part of the educational evaluation activity of the course and ethical approval was not required. Moreover, collected data do not compromise students’ privacy since the questionnaires were focused on vaccine knowledge and no questions other than full name and university registration number were requested. At the end of the ETA students were asked to fill in a brief satisfaction questionnaire that was completely anonymous.
Statistical Analysis
Results obtained before and after attending the ETA and results of the satisfaction questionnaire were analyzed. A descriptive statistical analysis was performed. Since variables were found to be normally distributed after have been tested through the Kolmogorov-Smirnov test, categorical data were reported as number and percentages and compared through the Chi-square test, while continuous data were reported as mean and standard deviation (SD), and compared with the Student’s t-test. Student’s t-test for paired data was performed in order to compare the total score obtained before and after attending the ETA. Results were considered statistically significant with a p-value of 0.05. All data were analyzed with STATA data analysis and statistical software version 17.0 (Copyright 1996–2022; Stata-Corp LP, College Station, TX, USA).
3. Results
Among a total number of about 1900 students eligible for this ETA (about 1450 medical students, about 420 pharmacy students, 23 trainees in Hygiene and Preventive Medicine), 449 students participated in the ETA on vaccines and vaccinations. Among them, 165 (36.8%) were students enrolled in the single-cycle degree in Pharmacy, 261 (58.1%) in the single-cycle degree in Medicine, and 23 (5.1%) in the postgraduate school of Hygiene and Preventive Medicine. Most students were females (n = 301, 67.0%), attending to the IV or V year of study (Table 1).
Overall, the participation in the ETA allowed students to improve their final score by 27.3% (p < 0.001; average improvement for individual students 26.59%). Pharmacy students reached a total pre-course score of 19/32 and a total post-course of 27/32 (+27.3%; p < 0.001), while Medicine students reached a total pre-course score of 22/32 and a total post-course of 31/32 (+27.6%; p < 0.001). Considering postgraduate students, their knowledge on vaccines and vaccinations improved by 10.8%, with a mean pre-course score of 26/32 and a mean post-course score of 30/32. T-student test for paired data showed statistically significant estimates in all student groups (Table 2).
Independently from the single-cycle degree/postgraduate course, both males and females improved their knowledge after attending the ETA. Females improved more than males, especially among Pharmacy students (Table 3).
Independently from the topic of each question, we observed a relatively low percentage of students who gave an incorrect answer during the post-course test (Table 4). The questions for which we observed a greater reduction in the total number of incorrect answers were: Question 1 (from 33.9% to 5.1%), Question 3 (from 35.6% to 5.1%), Question 7 (from 39.2% to 5.8%), Question 8 (from 47.2% to 15.0%), Question 9 (from 70.8% to 27.4%), Question 10 (from 54.8% to 12.2%), Question 12 (from 76.2% to 38.8%), Question 13 (from 34.5% to 2.7%), Question 14 (from 59.7% to 35.9%), Question 16 (from 59.2% to 27.4%), Question 20 (from 50.6% to 20.7%), and Question 23 (from 45.0% to 4.9%).
Figure 1 shows the percentages of students reaching the passing grade for each topic. The two topics with a low percentage of students reaching the passing grade pre-ETA concerned “pharmacovigilance of vaccines” and “vaccines development”. Higher percentages of passing grade were observed post-ETA among postgraduate students (Hygiene).
Details of ETA topics, questions, answers, and differences between pre- and post-course test results among the three student groups are reported in Supplementary Tables S1–S10.
The ETA was much appreciated by the students, considering the responses they gave in the satisfaction questionnaire: in particular, 56.0% of them gave the maximum score when asked for an overall judgement, 4/4 on a Likert scale (the rest—44%—assigned 3 points out of 4). Moreover, most of them (53.0%) found the ETA “very useful” (4/4 on a Likert scale basis), while the rest (47.0%) found it “useful” (3/3). No negative answers (2/4, 1/4, 0/4) were registered.
4. Discussion
The presence and the importance of vaccinology in most Italian universities increased in recent years, after a long period in which this topic had insufficient dedicated time in university courses [7]. This growth has been made easier by the gradual choice of most Italian Universities to abandon the traditional educational system based on monographic courses and by the adoption of extracurricular activities (ETA). To graduate in Medicine and Surgery and in Pharmacy at the University of Florence, a student must attend a certain number of hours of ETAs that can be chosen among different activities (courses, seminars, laboratory projects, etc.) and topics, according to one’s own personal interests.
The aim of this study was to evaluate the impact of a vaccination-related ETA on students’ knowledge on this specific topic: this was assessed by administrating the students the same questionnaire before and after attending the course.
The results obtained suggest that the ETA was highly effective in increasing the students’ knowledge on vaccination: despite good overall scores in the pre-course test, the different groups were able to increase their final score considerably. Specifically, Pharmacy and Medicine students reported an increase of more than +27.0% between the pre- and the post-course tests (from 19.2/32 to 26.8/32 for pharmacy students, from 22.0/32 to 30.1/32 for Medicine students, p < 0.001). The improvement reported by the postgraduate students is also remarkable if considering the excellent knowledge of vaccine-related topics showed by the results of the pre-course test (their mean pre-course score was 26.3/32, while the mean post-course score was 29.6/32, p < 0.001). The success in strengthening vaccine learning was demonstrated by a remarkable increase in the percentage of post-course correct answers: no question—when considering the whole group of attendees—reported more wrong answers in the post-course questionnaire than in the pre-course questionnaire.
The traditional educational system (monographic course) does not appear to meet students’ expectations, and students often feel insufficiently prepared about the immunologic principles of vaccination and the epidemiology of vaccine-preventable diseases [12].
To enhance knowledge acquisition and to increase the attractivity towards vaccination or other topics, thematic summer camps—as those described by Vorsters et al. [13]—could be an interesting complement to the traditional academic curriculum.
Within the University context, extracurricular courses and activities such as the ETA presented in this manuscript become therefore particularly important, as they represent a powerful tool to increase medical students’ knowledge and engagement with the topic of vaccination. This should not be underestimated, as the importance of different sources of information on vaccines and vaccination has recently been highlighted due to its potential impact on the willingness to get vaccinated against COVID-19 or promote COVID-19 vaccination [14]. Moreover, ETAs are generally well accepted and welcomed by the students, as also shown by the results of the anonymous satisfactory questionnaire on the ETA presented in this manuscript.
The results of our study show indeed that training activities as the one that was held in April 2021 at the University of Florence could be considered an effective strategy to improve future healthcare workers’ knowledge about vaccinations. The importance of such interventions is dual: it is widely known that healthcare workers with better knowledge on vaccines and vaccination are more likely to get vaccinated than others [15]. This also applies to future healthcare workers, such as medical students, nursing students, and pharmacy students [16]. Moreover, a higher level of knowledge about vaccination is usually associated not only with a stronger willingness to be vaccinated but also with a higher chance to recommend appropriate vaccinations to patients [17,18].
This activity was offered and delivered during the COVID-19 pandemic and specifically in the very first period of the Italian COVID-19 vaccination campaign, which started in January 2021: in facts, the ETA was realized when the interest towards vaccinations was at its peak, when almost all healthcare workers have already been vaccinated and different groups (e.g., students in the healthcare area and teachers) in the population have started booking (or received) their first shot. This may somehow explain both the interest raised by this educational opportunity and the good knowledge shown by the students in the pre-test course.
This study presents certain limitations. As previously specified, the course was not mandatory but optional. This explains why the sample size is relatively small, if compared to the number of students attending the Medical School at the University of Florence. Moreover, for the same reason, it is possible that the success of this ETA was somehow driven by the strong personal interest shown by the participating students. Finally, it was not possible to enrich the study with more demographic data such as age, which would give a more in-depth understanding of the presented phenomenon.
5. Conclusions
This study deals with the attempt to organize, fulfil, and evaluate the impact of an ETA focused on vaccination which was directed to future pharmacists, medical doctors and specialists in Public Health and Preventive Medicine. We believe that a thorough knowledge on vaccines and vaccination will be increasingly required to future health care workers, especially after the COVID-19 pandemic and the rollout of COVID-19 vaccines, and therefore we consider these activities important to integrate knowledge and attitudes regarding vaccinations. The next generation of healthcare professionals should receive appropriate education, knowledge as well as technical skills on vaccines and vaccination, as this will help them recommend appropriate vaccinations to patients.
