Additional Editor Comments (if provided):

Dear Authors:

Thanks for submitting your article to our journal. To facilitate the process of our reviewers and future readers, please add to the supplementary material: the searching strategy and the table of excluded articules (with the reason of exclusion). In the line 176, double-check if it is right the text "second reviewer". Also, double-check the title in the Table 2 (supplementary file).

Given that you submitted by first time this review on February 2022, I will consider, after your adjustments, to send your article to our reviewers. However, if they comment that the paper should be updated (to be less than one year old), I will accept their suggestions. I mention this, to prepare you, in case this happen.

Additionally, I suggest to draw the PRISMA figure using the classic format, consolidating the final updated strategy, with the previous one. Within the boxes, or at the foot of the Figure, you could include the respective explanations.

Please send us these initial adjustments, to be able to submit it to the reviewers.

Reviewer's Responses to Questions

Comments to the Author

1. If the authors have adequately addressed your comments raised in a previous round of review and you feel that this manuscript is now acceptable for publication, you may indicate that here to bypass the “Comments to the Author” section, enter your conflict of interest statement in the “Confidential to Editor” section, and submit your "Accept" recommendation.

Reviewer #1: (No Response)

Reviewer #2: All comments have been addressed

**********

2. Does this manuscript meet PLOS Global Public Health’s publication criteria? Is the manuscript technically sound, and do the data support the conclusions? The manuscript must describe methodologically and ethically rigorous research with conclusions that are appropriately drawn based on the data presented.

Reviewer #1: Yes

Reviewer #2: Yes

**********

3. Has the statistical analysis been performed appropriately and rigorously?

Reviewer #1: Yes

Reviewer #2: Yes

**********

4. Have the authors made all data underlying the findings in their manuscript fully available (please refer to the Data Availability Statement at the start of the manuscript PDF file)?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception. The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

6. Review Comments to the Author

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: The article raises a very important issue of health equity pertaining to the indigenous population. the manuscript however requires English editing to ensure usage of consistent and standard terminology throughout. Eg- "2009pH1N1" being used to denote the 2009 influenza pandemic. The manuscript would have been easier to review if the tables and figures were kept at the end of the main body instead of in between the body of the text.

Reviewer #2: This is a properly executed systematic review and meta-analysis on an important topic. I only have one comment (I am reviewing a revised version of the manuscript): country-level estimates for both USA and Canada rely solely on data from the 2009-10 H1N1 pandemic. This not only represents a limitation of the data, but also an important knowledge gap that needs to be addressed in future work. I think that this point warrants a sentence or two in the Discussion
