1. Introduction
COVID-19, first reported in Wuhan, China, spread rapidly across the world in just one month, causing a global public health emergency [
1]. The World Health Organization (WHO) classified the novel coronavirus disease (COVID-19), caused by severe acute respiratory syndrome, coronavirus 2 (SARSCoV2), as a global pandemic on 11 March 2020 [
2]. COVID-19, mainly respiratory viruses, can also be transmitted through aerosols made by infected people, including those who are asymptomatic [
3]. The clinical features of this disease include asymptomatic or moderate symptoms, such as fever, cough, sore throat, and headache, or severe symptoms, including acute nasal congestion such as pneumonia, respiratory failure requiring mechanical ventilation, multi-organ failure, sepsis, and death [
4]. COVID-19 infection caused by the SARS-CoV-2 virus affects only 2% of children and young adults. Children with COVID-19 infection have been reported to have severe COVID-19 infections and deaths, but the numbers are lower than those for adults. As the epidemic progresses, more direct and indirect effects become apparent. The side effects of COVID-19 have had serious repercussions on children’s health and well-being because of truancy, health care, mental health, and social repercussions [
5].
Managing COVID-19 requires taking several precautionary measures to protect healthy people from contracting the virus. One of the key methods of managing the transmission of the virus is maintaining a physical distance from other people. This can be conducted by staying at home and only traveling or going out in public when necessary. Additionally, when one is out in public, it is recommended that one should maintain at least two meters distance [
6]. Crowded areas should also be avoided as the virus can be transmitted through the air. Another method of avoiding COVID-19 is wearing masks, especially in public. Wearing protective masks prevents aerosols from an infected person from reaching healthy people, especially when they are in close contact [
7]. Even though the preventive precautions described above are no longer mandatory, the WHO [
8] maintains that vaccination is, without a doubt, the most significant clinical approach for effective disease prevention and control [
8]. According to the published research data [
9], immunization not only reduces the likelihood of developing an infection but also, on average, resulted in a less severe presentation of COVID-19. As a result, having an effective vaccine available will aid in preventing susceptible people to contracting the virus and providing comprehensive immunity to end the COVID-19 pandemic.
Vaccines are biologics that provide dynamic, adaptable immunity to specific illnesses and contain medications that mimic the germs that cause infection [
10]. To stimulate the immune system to make antibodies that recognize and neutralize infectious germs, they are commonly made with killed or attenuated microbes, their surface proteins, or toxins, which are swallowed or inhaled [
11]. Vaccines come in various forms, each designed to train our immune systems to combat invading microorganisms. Subunits, recombinant, live-attenuated, inactivated, toxoid, and conjugated vaccines are the four types of vaccinations available [
12].
The FDA approved the Pfizer-BioNTech COVID-19 vaccine (mRNA) for emergency use in December 2020, making it the first COVID-19 vaccine. The FDA has since approved the SII/COVISHIELD (
Adenovirus rector) and AstraZeneca/AZD1222 vaccines (
Adenovirus rector), the Janssen/Ad26.COV 2.S vaccine (
Adenovirus rector) developed by Johnson and Johnson, the Moderna COVID-19 vaccine (mRNA), the Sinopharm COVID-19 vaccine (inactivated virus), the Sinovac-CoronaVac vaccine (inactivated virus), the Bharat Biotech BBV152 COVAXIN vaccine (inactivated virus), the Covovax (NVX-CoV2373) vaccine (subunit vaccine), and the Nuvaxovid (NVX-CoV2373) vaccine (subunit vaccine) for emergency use in the prevention of COVID-19 [
13].
Children are the primary target demographic for vaccination [
14], and many countries worldwide have taken various steps to boost their children’s immunization rates. Despite this, there has been an upsurge in parents refusing or delaying vaccinations for their children. According to a data analysis of the WHO and UNICEF joint report (2015–2017), parental vaccination hesitancy has been observed in more than 90% of nations worldwide [
15]. As a result, vaccine hesitancy research has shifted its focus to parents’ attitudes toward immunization [
16].
Recent statistics imply that nations such as America may never attain herd immunity. Nevertheless, because children comprise 22% of the American population, engaging children in the vaccination efforts and planning is critical for enhancing community protection against COVID-19 [
17,
18]. Understanding the disparities in COVID-19 vaccination apprehension across various communities and sociodemographic categories is crucial for identifying those for whom the current COVID-19 vaccine information may be insufficient to increase uptake. Based on this information, vaccine communication and distribution techniques could be customized towards hesitant populations. Several variables can impact a parent’s decision to withhold immunizations from their children. Riyadh is the capital of Saudi Arabia and exhibits a cosmopolitan society with people from different social, religious, and professional backgrounds; it may represent the nation’s mood. Therefore, it was decided to carry out a questionnaire-based cross-sectional study in Riyadh city to explore the prevalence of COVID-19 vaccine hesitancy among parents toward their young children and determine the factors that may influence their decisions.
2. Materials and Methods
2.1. Study Design, Participants, and Settings
This observational cross-sectional study was carried out in the Riyadh region of Saudi Arabia between February and April 2022. All residents of Riyadh region of Saudi Arabia who were 18 years or older, parents of children between the ages of 5–11 years, and ready to participate were eligible to be included in the study. They were approached at several locations, such as malls, supermarkets, gardens, primary health centers, children’s parks, hospitals, and health camps. They received an online questionnaire link in Google form. At the beginning of the online form, the study’s objectives and informed consent were stated, and parents could choose to participate or decline, making participation voluntary. The participant was requested to register their response by self-administration. The research proposal was approved by the institutional ethical committee of AlMaarefa University with reference number IRB06-06032022-21.
2.2. Determination of Sample Size
2.3. Study Questionnaire, Validation, and Pretest
The research team developed the questionnaire with the help of the published literature. Further, it was validated with the help of experts in the field of community health, epidemiology, immunology, pediatric, social health, and pharmacy practice professionals. The questionnaire was translated into Arabic with the help of bilingual professionals by the forward and backward methods. As part of the pilot/pretest, a questionnaire was initially distributed to 30 eligible participants to determine whether a better understanding of any of the study questions was needed. Some questions and statements were rephrased at the end of the pilot study to improve its knowledge. The reliability of the study questionnaire was confirmed by checking the Alpha Cronbach factor, which was found to be 0.82. Finally, a bilingual (Arabic and English) questionnaire was used for the study.
2.4. Study Questionnaire
There were four sections in the questionnaire used in the study. All of the sections and items included in each section were required to be completed by the participants. The four sections were sociodemographic characteristics, COVID-19 infection status in the family, COVID-19 vaccination status, and COVID-19 personal preventive measures.
2.4.1. Sociodemographic Characteristics
This section had eleven items to determine the age of the participants, their nationality, gender, marital status, educational level, income range, employment status, whether they work in the healthcare sector, any specific illness of the child, and their child’s routine vaccination status.
2.4.2. COVID-19 Infection Status
This section explored whether the child/children and any family member was/were ever infected with the COVID-19 infection (yes or no) and the severity level (asymptomatic, mild symptoms, moderate symptoms, severe symptoms).
2.4.3. COVID-19 Vaccination Status
This section recorded the COVID-19 vaccination status of the child and the family. It also documented the number of jabs that the parents and their children had received. Further, parents who were not ready for their children’s vaccination were inquired about the possible reasons for avoiding it. The reasons that were put forth to the participants were: (a) Inadequate data about the safety of a new vaccine; (b) I am against vaccines in general (or I avoid medications whenever possible); (c)Vaccine administration is painful or inconvenient; (d) My child already had a COVID infection; (e) A concern about the adverse effects of the vaccine; (f) A concern of the vaccine being ineffective from COVID mutations; (g) Prior adverse reaction to the vaccine; (h) I perceive my child as not at high risk to acquire COVID-10 infection; and (i) I perceive my child as not at high risk to develop complications if he/she contracts COVID-19. Those parents who were reluctant to vaccinate their children were also inquired about the influencing factors for their decision. The following list was presented to them for the selection of relevant factors: (a) Social media; (b) Religious belief; (c) Family members; (d) News articles; (e) My child’s poor perceived immunity; (f) My dislike of the vaccine; and (g) My colleagues.
2.4.4. COVID-19 Personal Preventive Measures
This section was intended to determine the parents’ regular practice towards personal preventive measures during the pandemic. They were inquired about family commitment, the use of protective items, and avoiding crowded areas during infection. The recording was conducted using a Likert scale ranging between every time, often, sometimes, and never. With the inclusion of four extreme possibilities, we picked this scale to eliminate the influence of a neutral choice [

2.5. Data Analysis
The data collected were entered into the SPSS IBM statistical package (version 25). Univariate descriptive analysis of the socio-demographic characteristics of the study sample and bivariate analysis, using the Pearson Chi-square test, were conducted. The factors responsible for influencing the parents’ decision on vaccine hesitancy were determined using stepwise binary regression analysis, followed by multinomial regression analysis, to calculate the odds ratio. A P-value of less than 0.05 was significant.
4. Discussion
This study determined the prevalence of vaccination hesitancy among Riyadh city parents regarding their children receiving the COVID-19 vaccine. According to our findings in this study (up to April 2022), more than half of the parents needed more time to be ready or were unsure whether to vaccinate their children against COVID-19. This trend of vaccination apprehension is more common among parents who have only had one or two doses of the vaccine, are less educated, have children who have previously been infected with COVID-19, and are relatively young (less than 44 years). In addition, most parents who oppose the vaccination are apprehensive about the perceived adverse effect and safety of the approved vaccines for children.
Previous studies have found that hesitant parents are reluctant to vaccinate their children even for routine vaccinations and that 25.8% of parents still need to be ready for the annual influenza vaccine [
19]. As a result, a similar barrier was envisaged for COVID-19 immunization, allowing policymakers and strategists to address vaccine skeptics’ concerns [
20]. As a result, healthcare personnel were included in the CDC’s effort to reinforce or strengthen the streamlining of accurate information to the general population. As is the case in any other society, Saudi Arabia faces challenges in vaccinating children. According to previous research from Saudi Arabia [
21], 61.9% (up to November 2021) were hesitant to vaccinate. Our research shows that 33.8% are unwilling to vaccinate their children against COVID-19, while 24.7% are undecided, totaling a worrisome 58.5% vaccine aversion. This indicates that there has been no significant improvement in the vaccine acceptance rates between November 2021 and April 2022. Only 35% and 33% of hesitancy are reported in studies from Qatar [
22] and Chicago [
23], respectively, although both types of research included parents with children older than 11. According to an article from Israel with a similar sample population, 43% of people were hesitant [
24]. However, recent research from other countries has indicated lower percentages of vaccination hesitancy. For example, studies from China, Vietnam, and Italy found that roughly 26%, 21%, and 18% of parents were hesitant to vaccinate their 5–17 year old, 3–17 year old, and 12–18 year old children [
25,
26,
27]. These findings point to a decrease in parental apprehension over immunization. Although there was a trend toward higher hesitancy when parents of children under the age of 12 were included in the research, the results were inconsistent between nations, indicating that the actual rate of reluctance varies.
Previous research has linked conspiracy theories, fake news, and social media to vaccine apprehension [
28,
29]. Our study discovered that social media contributed more than any other component to the public’s development of parenteral fear regarding COVID-19 immunization by circulating false news or insufficient facts. In more than half of the instances, other factors contributed to vaccine reservations, including poor perceived immunity, news publications, insufficient knowledge, transmission from colleagues and friends, and religious beliefs. Vaccination apprehension among the general population is usually due to a lack of awareness about vaccine safety profiles [
30]. The top two reasons for the parents in this study developing reluctance to immunizing their children were concerns about side effects (31.4%) and a lack of safety evidence (31.2%) on the COVID-19 vaccines (
Figure 1). Other explanations were personal anti-vaccination attitudes, previous COVID-19 infection, the belief that their child would not develop complications even if infected, pain at the injection site, and a history of adverse vaccine reactions. Beyond a rational “risk vs. benefit” examination, an individual’s vaccination decisions are influenced by various factors. They should thus be viewed as a continuum rather than a binary (anti-vaccine vs. pro-vaccine) viewpoint [
31]. The continuous nature of vaccine acceptance allows us to obtain a better picture of vaccine opponents, who are more diverse than one might think.
Our study found several demographic characteristics playing a significant role in developing vaccine hesitancy. The WHO have noted that this as a major threat to global health from preventable illnesses [
32]. Compared to other age groups, a significantly (
p = 0.001) larger proportion of younger parents (18–34 years) had reservations about their children receiving the COVID-19 vaccine. Our study findings are similar to two other studies reported recently. In a Turkish survey, willingness to allow their children to receive the COVID-19 vaccine was higher among parents aged 40 or older compared with those aged 18–29 years old [
33], and according to a study conducted in Brazil, younger age participants were associated with a refusal of the COVID-19 vaccine for their children [
34]. Young parents may be influenced easily by fake news or misinformation and therefore develop hesitancy about children’s vaccination. On the contrary, a study [
35] from China reported no significant impact of the parents’ age on developing children’s vaccine hesitancy. Nevertheless, educating young parents more convincingly about successful vaccinations is important. Further, the low level of education of the parents was a significant factor for their reservations about children’s vaccination. There are variations in the published literature on this aspect. For example, a study [
36] shows an inverse correlation between the parent’s educational level and vaccine hesitancy, while another study [
37] did not find any correlation between these factors.
This study has a few limitations, but it also offers some advantages. The study’s cross-sectional design and reliance on self-reported data make it impossible to track the participants’ ultimate vaccination decisions for their children. In addition, we could not quantify the study’s response rate as the online questionnaire approach we employed did not allow us to tally the number of invitations sent to parents. As a result, it needs to be clarified whether the group that did not participate in the study had different outcomes than the cohort that did, which could indicate selection bias. Furthermore, the study’s over-representation of females could be a contributing issue. As females were more hesitant to vaccinate their children than males and because females were overrepresented in the survey, our findings may exaggerate the actual hesitation rate. Other studies have evaluated vaccine reluctance among parents of all children under 18 years, while this study focused on parents of 5–11 year old children.
