Determinants for Acceptance of COVID-19 Vaccine in Nigeria

Abstract

Background: The coronavirus disease 2019 (COVID-19) pandemic heralded an unprecedented race to the development of several vaccine candidates at record speeds never seen in global health. Within nine months, Pfizer-BioNTech’s COVID-19 vaccine was approved by the United States FDA. Unfortunately, while these advances were ongoing, there was a burgeoning epidemic of disinformation about the virus and the vaccines that affected the willingness of people, especially minority groups, to get vaccinated. In Nigeria, this wave of vaccine hesitancy was happening against the backdrop of landmark pharmaceutical litigations such as the 2007 Pfizer trovafloxacin lawsuit in the country.

Aim: To assess the determinants of the COVID-19 vaccine's acceptability among Nigerians.

Materials and methods: Following ethical approval, a population-based cross-sectional study was conducted from November 2020 to January 2021 using an adapted pretested, self-administered questionnaire originally designed by Amyn Malik and colleagues who conducted a similar study at Yale University School of Public Health. The participants were recruited through simple random sampling using a list of community and corporate sites obtained from Google Maps in the three regional zones of Nigeria (north, east, and west) in diverse occupational and residential settings. Information obtained includes socio-demographics, medical history related to COVID-19, level of knowledge, risk perception, and attitudes toward COVID-19 and the vaccines. Descriptive and inferential statistics were done, and results were summarized into percentages and associations. The level of statistical significance was set at a p-value of <0.05. Using the open EpiR package (Emory), we determined a minimum of 340 participants for a statistical power of 80%.

Results: A total of 358 responses were obtained out of the 120 questionnaires distributed in each of the three regions, of which 189 (53%) were females. The mean age of respondents was 32 years (±11.2 SD). About 75% of the participants had at least a college education. The majority (66.2%) of the participants were willing to accept the approved vaccine. The mean risk perception score for COVID-19 was 5.1 (±2.2 SD) out of 10, while the mean COVID-19 symptom knowledge score was 8.6 (±4.1 SD) out of 19. Variables such as being male, identifying as Christian, Hausa ethnicity, and living in northern Nigeria had a statistically significant relationship with the willingness to get vaccinated.

Conclusion: Over 60% of Nigerians are willing to take the COVID-19 vaccines if recommended by health workers. We found male gender, religion, ethnicity, and geographical location to positively influence the willingness of Nigerians to get vaccinated against COVID-19. Health workers should be supported to go beyond the confines of the hospital to educate the general public in schools, marketplaces, churches, and corporate organizations on the efficacy and safety of the approved vaccines.

Introduction

The coronavirus disease 2019 (COVID-19) was first reported in the Wuhan province of China in December 2019 before spreading rapidly throughout the globe. It was first reported in Nigeria on February 27, 2020. Around the same period, experts projected that Nigeria will likely become the pandemic’s epicenter in Africa [1]. Contrary to these projections, the disease ran a relatively less severe course in Nigeria and in most countries south of latitude 350 north, within which the whole of Sub-Saharan Africa falls [1]. As of March 2020, the World Health Organization published a case fatality rate (CFR) of 3-4%. In the West African sub-region, the average CFR is 3.9% [2]. In February 2021, Suleiman et al. estimated the CFR in Nigeria using polynomial regression models to be 3.0% (95% CI: 2.23-3.42%) [3]. This estimate would have been lower if there was widespread testing. Despite speculations that Africa would be the worst hit by the pandemic due to its weak healthcare systems and relatively higher population density, the predicted catastrophe is yet to happen [4]. As of September 24th, 2021, about 3 million COVID-19 tests (1.5% of the population) have been conducted with about 6% confirmed to be positive. Similarly, COVID-19 vaccinations have remained relatively low as only 1.58 million (0.8%) people have been fully vaccinated as of September 24th, 2021 [5].

Unfortunately, despite the daily exponential increases in recorded cases in Nigeria, there is a growing body of anecdotal evidence that many Nigerians do not believe in the existence of the pandemic. This is due in part to low trust levels in the government and a plethora of conspiracy theories surrounding the virus and vaccines by influential Nigerian political and religious leaders [6]. The surprisingly low CFR may have also contributed to the attitude of Nigerians and Africa at large towards the existence of this virus.

A vaccine is a live or attenuated antigen used to stimulate antibody production to provide immunity against pathogens like bacteria and viruses. Vaccination is one of the most potent preventive strategies against infectious diseases [7]. However, acceptance and coverage are vital determinants for a successful vaccination program [8]. With the approval and rollout of some efficacious and safe vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), there has been an attendant epidemic of misleading information about the approved COVID-19 vaccines. This misinformation is not limited to Nigeria alone. Several media reports suggest that distrust in the United States and Europe has become a major obstacle to wider vaccine coverage [9-11]. Malik et al. at Yale University found that only 67% of the Americans they surveyed were willing to be vaccinated against COVID-19 before any vaccine was approved. This proportion has however improved since then [8,12]. Surveys conducted by GeoPoll in some African countries show that vaccine hesitancy decreases as more vaccines are rolled out [13]. As of September 2021, only about 1.5% of Nigerians have been vaccinated [6]. There are mixed feelings about the facts established on the evolution of the pandemic as well as with the vaccine’s efficacy and safety [14]. Despite these reactions, an online survey in Nigeria that was conducted just before the first-ever vaccine was approved reported that 58.2% of respondents would receive the vaccine once available while 19.2% and 22.6%, respectively, were unwilling or indecisive [15].

The purpose of our study is to assess the degree of acceptance of the approved COVID-19 vaccines among Nigerians, and the factors that influence the decisions to get vaccinated. The findings of our study are intended to support health policymakers, donor agencies, and other critical stakeholders to implement evidence-based strategies that are likely to be effective in the reduction of vaccine hesitancy and to ultimately increase vaccine uptake as more doses become available in Nigeria.

Materials and methods

Study area

Nigeria is on the western coast of Africa. It is the most populous country in Africa, with an estimated population of about 206 million people [16]. It has 36 states, which are broadly divided into three ethnic-regional blocs: Eastern, Northern, and Western Nigeria.

Study design and participants

We conducted a cross-sectional study across Eastern, Northern, and Western Nigeria over a period of three months from November 2020 to January 2021. We used the open EpiR package (Emory) to generate the required minimum sample size of 340 for a population of one million and above [17].

We recruited 360 participants in total, 120 from each zone. Our recruitment was targeted at people in residential areas, corporate organizations, schools, recreational areas, faith-based institutions, and marketplaces. We did this by using Google Maps to list the aforementioned sites in two major states of each zone (north, west, and east). We then organized the list on Microsoft Excel version 16.54 (Microsoft Corp., Redmond, WA) and used the Rand() function to randomize each site list, and then we selected two sites for the recruitment. For the institutions, we contacted the human resources or desk offices to grant permission to visit and interview eligible participants in these sites. For the residential areas, we repeated the same Microsoft Excel process to randomize and select local government areas (counties) in the two states in each zone and residences to visit. Study participants who were 18 years and older at the time of data collection were eligible to be included in the study. Our exclusion criteria were people who were below 18 years and those who did not fully understand the reason for the study even after our explanations.

Study tool

Our data collection instrument was a pretested, self-administered questionnaire formulated from a similar study in the United States adapted to suit the Nigerian setting [9]. The questionnaire was divided into five sections comprising participants' socio-demographics, medical history, knowledge of COVID-19, risk perception on contracting COVID-19, and personal and behavioral attitudes to the approved COVID-19 vaccines.

Scales of measurement

Three multiple-choice questions (totaling 10 options) were asked to assess respondents' knowledge about the transmission of the COVID-19 virus. The scale was called the viral transmission knowledge scale (Cronbach's alpha = 0.62). A maximum score of 10 was achievable. These responses had reverse meaning; higher scores reflected poorer knowledge of viral transmission.

We assessed the knowledge of participants on 11 common symptoms and signs of COVID-19 culled from the Nigeria Centre for Disease Control (NCDC) [5]. This formed the symptom knowledge scale (Cronbach's alpha = 0.86). A maximum score of 19 was attainable and higher scores depicted better knowledge of features of the disease.

We also assessed universally acceptable measures to prevent contracting or spreading COVID-19. Questions included hand washing, use of hand sanitizers, physical distancing, healthy diet, among others. This scale was termed the preventive measures knowledge scale (Cronbach's alpha = 0.61). Correct responses had a score of 1 while incorrect responses had 0 to make a total score of 19 with regards to knowledge of preventive measures.

A previous study had assessed COVID-19 risk perception among adults in the United States using a “perceived risk perception scale” (Cronbach’s alpha = 0.72) [8]. This risk scale was validated for the study and locally adapted. Thereafter, respondents completed the validated perceived risk perception scale (Cronbach's alpha = 0.63), which had 10 survey items (five-point Likert scale: 0 = strongly disagree/disagree/neutral; 1 = agree/strongly agree). The scoring of the perceived risk perception scale, which ranges from 0 to 10, was calculated by summing the participants' responses of "Agree" and "Strongly Agree" to 10 survey items. The greater the number a participant receives on this scale, the greater their perceived risk of COVID-19 (see Appendix).

Data analysis

The Statistical Package for Social Sciences, version 22 (IBM SPSS Statistics, Armonk, NY) was used for data analysis. We reviewed and cleaned the data before the analysis. Variables were summarized using simple frequencies, proportions, and percentages. Inferential statistics (chi-square test) and bivariate analysis were used to test factors associated with acceptance of the COVID-19 vaccine. A 95% confidence interval and a significance level set at p < 0.05 were adopted.

Ethical consideration

The study was approved by the Ethical Committee of the Research and Statistics Department of Katsina State Ministry of Health, Nigeria with the study protocol code: MOH/ADM/SUB/1152/1/16. Written informed consent was obtained from each study participant before the questionnaire was administered.

Results

A total of 358 out of 360 participants completed the survey, giving a completion rate of 99.4%. Table 1 shows the sociodemographic characteristics of the participants. The mean risk perception score for COVID-19 was 5.1 (±2.2 SD) with a possible maximum of 10 while the mean COVID-19 symptom knowledge score was 8.6 (±4.1 SD) with a maximum score of 19. The mean preventive measure knowledge score was 10.8 (±2.0 SD) with a maximum score of 14 (Figure 1).

Of all the participants surveyed, two-thirds of them reported they would take the COVID-19 vaccine if it is recommended by healthcare workers or health agencies like WHO, NCDC, or the National Primary Healthcare Development Agency (NPHCDA). In contrast, only 71 people (19.8%) said they will take the vaccine regardless of who recommends it. About 203 (56.7%) of the participants said they will recommend the vaccine to other people.

There was a statistically significant association between the male gender and COVID-19 vaccine acceptance if recommended by a health worker (73.9%, p-value = 0.027). Similarly, we noted that participants of Hausa ethnicity were more likely to take the vaccine if recommended by a health worker compared to other ethnic groups (84.9%, p-value = 0.007). The recommendation of COVID-19 vaccines by a health worker or health agency, and the three major regions where we recruited our participants were associated with vaccine acceptance as summarized in Table 2.

Discussion

The proportion of people willing to take the COVID-19 vaccines from our study was similar to the 67% reported by Malik et al. at Yale but higher than 58.2% earlier reported in Nigeria by Olumofe et al. [9,16]. The figures from our study and Malik et al. were lower compared to the findings by Abdelhafiz et al. in Egypt where 73% were looking forward to getting the COVID-19 vaccine when available (this was done before the first vaccine approval) [9,18]. Since the ultimate aim of vaccination is to achieve herd immunity, the estimate from our study and the one reported by Olumofe et al. fell short of the minimum 75% vaccination rate needed to achieve herd immunity among the population. This is with the assumption that there are going to be enough vaccine doses procured to vaccinate at least 150 million Nigerians. Additionally, given the high efficacies (62-94.5%) of the vaccines approved so far, at least 75% to 95% vaccination coverage is required to achieve herd immunity [19]. Care should be taken in interpreting the estimated acceptance rate as they do not automatically translate to actual average vaccination coverage. For example, factors such as proximity and cost of going to vaccination sites and availability of vaccines could potentially affect the number of those willing to take the vaccine from getting one. Nonetheless, the data from this study can serve as an important pointer that critical stakeholders need to do more in terms of vaccine awareness and education to improve the uptake as it is being rolled out, including teasing out sensational news on perceived side effects from factual scientific evidence. A distinct picture from this study is the fact that even though an overall 66.2% of our participants indicated they would take the vaccine, many of them would do so on the recommendation of respected figures like healthcare workers or health agencies [20]. As reported by Malik et al., potential vaccine takers have the highest confidence in healthcare professionals, their physicians, and health institutions like the CDC and WHO [9]. Vaccine education offered by individuals with a better understanding of the net benefits of vaccination against SARS-Cov-2 is extremely important in combating the hesitancy that may be seen in the general Nigerian population. These tasks should not be left to healthcare providers alone. Rather, it must also come from the cross-section of religious, traditional, and political leaders who are revered and respected in society [21,22].

Educational status among the populace has been shown to affect vaccine uptake. Findings from a systematic review on the determinants of the 2009 pandemic A/H1N1 influenza vaccination were consistent with our study and similar studies done elsewhere [23,24]. The positive association between the levels of education and vaccine uptake is also consistent with polio vaccine hesitancy studies. A number of these studies showed that there were higher odds among women with no education of their child not being vaccinated for polio [25]. According to a multinational European survey on influenza vaccination uptake, the effects of education varied from one country to another [26]. In Australia and Poland, influenza vaccination was higher among educated people whereas a contrary trend was observed among educated persons in Germany and Finland [26]. This further validates the earlier suggestion that other factors could water down the influence of education on vaccine uptake.

There was a significant association between vaccine acceptance or uptake and male gender, tribe/ethnicity, religion, and place of residence. Olumofe et al. reported similar findings of the significant male influence of potential uptake of COVID-19 vaccine [16]. The influence of different levels of socio-economic statuses on the acceptance of COVID-19 vaccines in this study mirrors what others have reported both within and outside Nigeria [8,15,18,20]. As with our study, Malik et al. reported a significant association between vaccine acceptance and race/ethnicity, with being Black/African American and American Indian as independent predictors [9]. This implies that a one-size-fits-all messaging on COVID-19 and vaccines should be discouraged by health policymakers, rather, more targeted messaging should be considered.

One important improvement we did with the adaptation of the study by Malik et al. was the field approach we used in collecting data. By default, online surveys will naturally exclude people who do not have access to the internet, which is more than half of the Nigerian population as the estimated internet penetration in Nigeria is 46.6% [27]. This potential source of selection bias was eliminated in our study. On the other hand, a multistage stratified sampling technique was used for this population as described in the methodology. However, the stratification to an extent led to limitations in the inclusion of some formal groups of the general population. Additionally, due to funding restraints, the lack of stratification to the recognized geopolitical zones in Nigeria likely introduced some bias. For example, about 91% of our participants had at least a secondary school education, which is not in keeping with a lower adult literacy level in Nigeria. While we made efforts to avoid bias, as outlined in our sampling methodology, given our limited resources, there was still some degree of bias in the results obtained, thus affecting its representativeness of the general population.

Conclusions

Over 60% of Nigerians are willing to take the COVID-19 vaccine if recommended by a healthcare worker. Our study has highlighted important considerations and potential targets to incorporate in improving vaccine uptake. More than 50% of the respondents had a poor risk perception of being infected by COVID-19. Notably, being male, following the Islamic religion, being of the Hausa tribe, and living in the northern part of the country all have a significant positive association with COVID-19 vaccine uptake. More women, especially in southern Nigeria, need to be targeted, in addition to engaging influential religious and traditional leaders in vaccination messaging. Besides the insufficient supply of vaccines, vaccine hesitancy remains a major limitation to optimum vaccination coverage. It is therefore pertinent that as the supply of COVID-19 vaccines increasingly becomes available to Nigeria, strategies that are centered around support for public health agencies and health workers are key for effective public health messaging to increase uptake of the vaccines.
