Abstract

Background

The fight against the coronavirus disease (COVID-19), which has continued to threaten human existence globally, has led to the development of vaccines in order to control the rate of infection and death associated with the disease. Media messages on the COVID-19 vaccine are geared towards raising audience awareness and understanding of health risks, knowledge and attitudes about the vaccine safety.

Objective

The study examined the knowledge and attitude towards COVID-19 vaccine safety media messages amongst residents of South East, Nigeria.

Methods

A cross-sectional descriptive study was conducted among 399 respondents (18–47 years) in both urban and rural communities of South East, Nigeria from May 6th to July 4th, 2021. The survey was carried out using structured self administered questionnaire containing the respondents’ demographics, knowledge and attitudes towards media messages regarding COVID-19 vaccine safety. The data were analysed using the SPSS version 26 software. Result was presented in frequencies, percentages and charts showing the interrelatedness of the variables examined. Regression ANOVA was used to test hypotheses on the extent to which level of exposure to COVID-19 media messages predict their knowledge and attitude towards COVID-19 vaccine safety at P<0.05 level of significance.

Results

Data indicate respondents are apprehensive of taking the COVID-19 vaccine. Approximately, 91% of respondents are between the ages of 18 and 27 years. Meanwhile, 26.1% of the respondents agreed that media messages on COVID-19 vaccine is very assuring and convincing as regards human safety; 42.4% disagreed on the safety of COVID-19 vaccine safety messages; 26.1% rated vaccine messages as moderate as regards human safety, while 5.5% rated the vaccine messages as poor. Knowledge of respondents regarding the safety of the vaccine was low and respondents’ attitude was negative in South East, Nigeria. The implication is indicative of the failure of the main stream media in educating the general public on pertinent health issues relevant to them.

Conclusion

Knowledge regarding media messages on COVID-19 vaccine safety is low. Messages on COVID-19 vaccine safety were not sufficient and convincing. Consequently, there is a negative attitude towards the vaccine. Hence, improving knowledge and adoptive attitude amongst respondents amidst COVID-19 is critical.

Introduction

The challenges posed by the novel coronavirus pandemic since late 2019 till date are one of the worst health challenges recorded after the 1918–1920 flu pandemic that claimed over 100 million lives globally.Citation1 Coronavirus (COVID-19) is an illness of severe Acute Respiratory Syndrome caused by a novel coronavirusCitation2 and has become a major public health concern.Citation3 The disease is transmitted through saliva and mucus droplets from an infected person. The symptoms of the COVID-19 infection are similar to that of other beta coronaviruses.Citation4 Symptoms include fever, cough, dyspnea, weakness and fatigue, headache and diarrhea.Citation5 COVID-19 disease is posing a great global public health threat in our world today since the first quarter of 2020. The catastrophic news of the Corona-virus, which has claimed thousands of lives around the world, has had a tsunami effect on every nation in the first quarter of 2020, halting all global economiesCitation6,Citation7 without any notice or foresight from scientists and defying all scientific strength. Infected patients died at a higher rate, especially among the elderly who had underlying diseases such as cancer, diabetes, chronic respiratory disorders, acute cough, and so on.Citation8,Citation9 Despite the fact that COVID-19 had an effect on almost every continent on the planet, climatic conditions played a significant role in determining the pandemic’s global impact, taking into account the unique characteristics of each region.Citation10 However, regardless of race or age, the disease’s symptoms were the same. Death rates were being reported at breakneck pace in the newspapers, making it an especially trying time in human history.Citation11

COVID-19’s rapid spread is being investigated at all levels of human endeavor due to its grave consequences for all people affected across the world. The spread of COVID-19 is now relentless in almost all the countries of the world including Nigeria, causing serious public health, social and economic upheaval.Citation12–Citation14 The mere surface of this pandemic, defying all scientific prowess, has plunged the entire planet into chaos.Citation15 This conundrum necessitates a well-defined sequence and methodology that allows for adequate documentation of those impacted at all levels by the disease’s global impact. This, too, necessitates a strategic approach, especially in the case of disadvantaged groups of all kinds.Citation16 Data have it that millions of people are still dying daily irrespective of the availability of the World Health Organisation COVID-19 vaccine endorsement. The COVID-19 pandemic has created a new reality in which people are confronted with a previously unknown disease and its consequences, providing a unique opportunity to study vaccine attitudes at a time when disease awareness is high.Citation17

Vaccines are the most important public health measureCitation18 and most effective strategy for controlling diseases in many countries around the world.Citation19,Citation20 Moreover, the distribution of vaccines is highly significant in order to analyze community acceptance of COVID-19 vaccines.Citation21 All these call for a concerted effort to arrest the pandemic. Hence, there is a need to encourage the COVID-19 vaccination to reduce the propagation rate.

Ironically, the fear of death arising from COVID-19 disease and other controversies surrounding the vaccine safety in different parts of the world has increased fears in many Nigerians recently. Unfortunately, the approved COVID-19 vaccine seems not to guarantee safety as many have anticipated. It seems many people are not too eager to be vaccinated owing to the acclaimed side effects some health tips suggest such as myocarditis and Pericarditis associated with Pfizer and Moderna vaccine.

Consequently, spread of messages by the mediaCitation22–Citation24 through multiple channelsCitation25 have deliberately tried to douse fears and uncertainty regarding the vaccine safety. People tend to be more careful especially with the news of health complications resulting from those who have already taken the COVID-19 vaccine, especially the speculations that the vaccine alters ones “DNA”.Citation26 This is in addition to social media videos demonstrating the magnetic and lighting potency of vaccines if injected area of someone is touched with metal or electric bulb as the case may be. Similarly, effective communication to create confidence and reduce public ambiguity is critical for promoting vaccination acceptability, willingness, and uptake, avoiding vaccine hesitancy, and dealing with any infodemic on the topic, such as in the case of COVID-19 vaccines.Citation27–Citation32 has turned out to be unsuitable in addressing the issue. More so, it appears the body language of many Nigerians show likelihood and tendency of rejecting the vaccine even if it is made compulsory by the government.Citation33 Researchers have adduced reasons behind spreading of rumors, fake news, refusal of vaccine acceptance and vaccine hesitancy globally with regard to COVID-19 vaccine.Citation34–Citation38 Thus, reasons such as: Vaccine susceptibility, risk perception, and reactionCitation39–Citation44 certain religious beliefs, lack of knowledge and awareness.Citation45–Citation49 Likewise other reasons from Nigeria setting and other countries, such as poor health literacyCitation50,Citation51 conflicts and insecurities,Citation52 distrust in governments and firms that manufacture the vaccinesCitation49,Citation53–Citation59 remain a serious challenge.

There seems to be obvious speculation suggesting that many people in South-east geo-political zone still doubt the integrity of the COVID-19 vaccine in circulation currently. Respondents in this terrain still think of COVID-19 as propaganda. The vaccine is often referred to as a “trial vaccine” by many people.Citation11 The current status of Nigeria health care delivery discourages her citizens from even trusting on the integrity of the COVID-19 vaccine. Past research efforts indicated that people’s reluctance to receive the vaccine was caused by their anxiety and uncertainty about it.Citation41,Citation49,Citation57,Citation60–Citation62 Future health education initiatives should focus on enhanced understanding about COVID-19 via mass media messaging and cues from health-care practitioners’ recommendations to promote vaccine uptake by identifying a determinant that influences the intention to have the COVID-19 immunization.Citation59,Citation63,Citation64

Materials and Methods

A cross-sectional descriptive study was conducted among 399 respondents (18–47 years) in both urban and rural communities of Enugu State, Ebonyi State and Anambra State in South East region Nigeria from May 6th, to July 4th, 2021. The survey was carried out using structured questionnaire containing the respondents’ demographics, knowledge and attitudes towards media messages regarding COVID-19 vaccine safety. The Online Scientific sample size determination Australian calculator was used to select the sample size of 399.

Measurement

The data were analysed using the SPSS version 26 software. Result was presented on frequency tables, percentage and charts showing the interrelatedness of the variables examined. Regression ANOVA was used to test hypotheses on the extent to which the level of exposure to COVID-19 media messages predict their knowledge and attitude towards COVID-19 vaccine safety at P<0.05 level of significance.

Result

The result of the study as presented in shows the distribution of respondents by age, gender, religion, educational qualification and occupation. Result shows that majority of the respondents were between the age range of 28–37 representing 47.9%, while those within the age range of 18–27 and 38–47 were represented by 26.6% and 25.6%, respectively. Result also shows that 60.9% of the respondents are male while 39.1% are female. Also, result shows that 94.5% of the respondents were Christians while only 5.5% were Muslims. The reason for the high number of Christians is due partly to the fact that the area in which the study was carried out is dominated by Christian religion. On Qualifications, result shows that 26.6% are holders of B.Sc, 57.9% are with M.Sc while 15.5% are Ph.D holders. On Occupation, 26.6% are working class people, 16% are business men and women, 10.3% are unemployed while 47.1% of the respondents are students.

Hypotheses

Ho1: Respondents’ level of exposure to COVID-19 media messages will not significantly predict their knowledge on COVID-19 vaccine safety.

Result on whether the respondents’ level of exposure to COVID-19 media messages will not significantly predict their knowledge on COVID-19 vaccine safety showed that an f-ratio of (F(1, 398) = 67.77, p = 0.00) was obtained. Since the associated probability value (p-value) of 0.00 is less than 0.05 level of significance at which the result is being tested, the null hypothesis is not accepted and inference drawn is that respondents’ level of exposure to COVID-19 media messages is a significant predictor of their knowledge on COVID-19 vaccine safety. This means that exposure to COVID-19 media messages can significantly predict the extent to which the masses will accept that COVID-19 vaccine is safe.

Ho2: Respondents’ level of exposure to COVID-19 media messages will not significantly predict their attitude towards COVID-19 vaccine safety.

In order to test hypothesis two, result shows that an f-ratio of (F(1, 398) = 19.67, p = 0.00) was obtained. Since the associated probability value (p-value) of 0.00 is less than 0.05 level of significance set for testing the hypothesis, this means that the null hypothesis is not accepted. Inference drawn therefore is that respondents’ level of exposure to COVID-19 media messages is a significant predictor of their attitude towards COVID-19 vaccine safety. This equally implies that exposure to COVID-19 vaccine safety media messages can significantly predict attitude of masses towards accepting that COVID-19 vaccine is safe.

Discussion

The study aimed at assessing the knowledge and attitude of residents of south-east, Nigeria towards COVID-19 vaccine safety. Results show that majority (95%) of the respondents were exposed to media messages on COVID-19 vaccine safety in varying degrees in South east, Nigeria. While 42% were moderately exposed, 32% were well exposed and 21% were adequately exposed to the vaccine safety messages. Only 5% of the respondents were ignorant of the messages.

Findings of the current study regarding the source of exposure indicate that majority of the respondents were exposed to vaccine safety messages through the social media 35%, radio 26.3%, television 21.8%, 16.5% of the respondents who were exposed to COVID-19 vaccine safety messages through friends and families. The reason for social media been the dominant sources of the vaccine messages is not farfetched bearing in mind the popularity of the social media for information dissemination in contemporary times. The study also collaborates with the study of Zeballos et alCitation44 which found that social media exposure to COVID-19 information influences the adoption of preventive attitudes and behaviors through shaping risk perception.

This is in contrast with the study conducted by Al-Marshoudi et alCitation25 in Omani community’s which found that their willingness to take COVID-19 vaccine can be enhanced by utilizing social media and community influencers to spread awareness about the vaccine’s safety and efficacy. The result of this study indicates that the knowledge level of respondents on the safety of COVID-19 vaccine is low. Only 28.72% of the respondents are knowledgeable about COVID-19 vaccine safety messages. Respondents’ level of exposure to COVID-19 media messages is a significant predictor of their knowledge on COVID-19 vaccine safety. The study is similar to the findings of Islam et alCitation20 that indicated inadequate knowledge but more positive attitudes towards COVID-19 vaccine among the general population in Bangladesh. Also, another study by MesesleCitation3 in Ethiopia indicated poor knowledge towards COVID-19 vaccine. This means that exposure to COVID-19 media messages can significantly predict the extent of respondents’ knowledge towards the safety of COVID-19 vaccine.

The findings on attitude of the respondents towards the safety of COVID-19 vaccine show that majority of the respondents (60.10%) think that the vaccine is not safe. Respondents’ level of exposure to COVID-19 media messages is a significant predictor of their attitude towards COVID-19 vaccine safety. This equally implies that exposure to COVID-19 media messages can significantly predict attitude of respondents towards COVID-19 vaccine safety. The study is in agreement with Fridman et alCitation17 study that found a decline in general vaccine attitudes and intentions of getting the influenza vaccine. In addition, certain characteristics of the COVID-19 vaccines themselves like efficacy, safety, and side effects influence public attitudes.Citation38

Conclusion

Knowledge regarding media messages on COVID-19 vaccine safety is low. Messages on COVID-19 vaccine safety were not sufficient and convincing. Consequently, there is a negative attitude towards the vaccine. Respondents’ level of exposure to COVID-19 media messages is a significant predictor of their knowledge and attitude on COVID-19 vaccine safety. Hence, improving knowledge and adoptive attitude amongst respondents amidst COVID-19 is critical.
