Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: I read the manuscript entited "Association between social capital and COVID-19 vaccine trust and hesitancy". The concept is interesting but already it is old idea. I see many article in online about the COVID-19 vaccine hesitency. However, most of them are missing in present manuscript. Therefore, authors need to improve introduction and discussion based on present published articles. See some specific comments bellow:

- consent from individual was missing. If you have that, add in the data colection section

-Table 1: Age categories should be minimized, so many catagories is meaningless. So I suggested to have only 3/4 categories of age.

-How you divided the household incomes? You need to add references in the method section, how you divided the income division? Accordingly, re-arrange the Table 1 based on income categories!

-Rearrange Table 2 and 3 based on re-arranged categories of age and household incomes.

-What is your key findings from your study? Need to explain key messages in the conclusion part. Based on the key message, what is your recommendations.

-In Figure 1, you need to adjust age, and household incomes.

Reviewer #2: Thank you for the opportunity of reviewing the manuscript whose objective of is to analyze the differences in COVID-19 vaccine trust and hesitancy according to the various participants’ characteristics, including the social capital. Please find below my comments:

Title

1. I’m pretty sure the study does not only cover the association between social capital and COVID-19 vaccine. Other factors are also studied. Please modify the title to be more representative of the content.

Introduction

1. Line 51. “eight core capacities” please elaborate.

2. Line 59. “SC has been fund to effectively” please check the accuracy

3. Line 60—61. “Previous studies have reported that regions with higher SC..” Where were the studies conducted? The elaboration is important because the submitted study has a novelty of its population being Koreans.

4. Is COVID-19 vaccination a mandatory in Korea? How is the progress so far?

5. To strengthen the background authors may incorporate the following studies revealing about the COVID-19 acceptance. And please focus on the detailed factors (such as income, safety, etc.).

Suggesting:

Sallam et al. Narra J 2022; 2(1): e74 – doi: 10.52225/narra.v2i1.74

Rosiello et al. Narra J 2021; 1(3): e55-doi: 10.52225/narra.v1i3.55

Methods

1. Calculation of sample size and sample randomization should be disclosed in details.

2. “..careless responses (e.g. censored respondents) and those who withdrew from the survey..” How could censored respondents are categorized as those giving careless responses? Why the participants withdrew from the survey? Didn’t they receive informed consent first?

3. Inclusion and exclusion criteria need to be explicitly disclosed. How authors determine the participants are Korean citizens?

4. Questionnaire validation should be explicitly disclosed. The company identity (name and address) for each statistical software should be stated.

5. What “social organization involvement” means? Is being a member is enough? Should the social organization officially registered? This has to be declared in the methods.

Results

1. Please pay attention on how the data are cited in the text. Usually, the paragraph begins with a sentence indicating where the data are presented. For instance, “Characteristics of the participants have been presented in Table 1”. If authors decide to cite the data in parenthesis, the citation should be made in the first and the last sentence where the data are discussed in the paragraph.

2. For age, consider years old instead of years only.

3. As per international standards, the writing of p<0.000 should be revised to p<0.001

Discussion

1. Authors argue the low willingness in younger generation was resulted from the disinformation spread through social medias, while also arguing that the older generation consumes more reliable information through traditional news sources. Authors cited reference no 6 to strengthen the claim. I don’t think ref 6 is appropriately cited in the manuscript, the literature mainly reports on the preference of news sources for COVID-19 information. Age was only considered as factor affecting the participants’ knowledge on COVID-19, not on their media preference. My suggestion is to modify this part of discussion for better judicious interpretation by readers. Other pronounced factors affecting the disinformation pertaining to COVID-19 (such as education) should be discussed instead.

2. Can you perform the analysis on “social media vs. age” and “social media vs. vaccine trust/hesitancy”?

3. Authors should know that the hesitancy is not always coming from the absence of the knowledge (because of social media as claimed in the manuscript). People who are well informed could also be hesitant because of the safety risk of the vaccine (Rosiello et al. Narra J 2021; 1(3): e55-doi: 10.52225/narra.v1i3.55). Please revise the discussion by considering this.

4. Is there any limitation on the data quality of the SC. For example, being biased or not able to confirm?

Conclusion

1. “COVID-19 experts and celebrities to increase its credibility” Why celebrities are included to increase the credibility?

Reviewer #3: Thank you for the opportunity to review this article. This article has been revised twice. However, I still detected some unclear issues related to this study. Therefore, I include some suggestions that I believe will improve the quality of the manuscript. Please encounter my specific comments in the attached file.
