Reviewer 2 Report

This is an excellent paper with very timely and important findings.

Some notes for clarification:

1) Figure 2 is showing some stochastic behaviour, this is interesting for deterministic model. Is the incidence stochastic , how are multiple peaks appearing? do you change the parameters for each day?

2) Table 3. should read 200,000 vaccinated people.

3) Is your STELLA model available to other researchers?

Reviewer 3 Report

This is an interesting and worthwhile paper on an important topic in the prevention of COVID-19 worldwide.

1. In doing this, they make some assumptions about the reader's understanding of their methodology that makes the paper more difficult to read. The paper can be improved by being more explicit about how they estimated the different frames, and the underlying assumptions.

2. It is also not very clear how values for the non-vaccinated group were determined, was there any empirical data from this group? If not, then the assumptions about this group of patients underlying these estimates should also be made clear.

3. Vaccination coverage and attendance is also an important factor in a prevention programme, and the authors should make some consideration about those who were lost to follow up or simply did not attend for screening, and how this would affect the resources and success the recommended vaccination.

4. Did the authors take into account the indirect costs of complications from a societal perspective? If not, then the perspective of the present analysis should also be made more clear.

5. How is the discount rate? It would be helpful for other researchers looking at the same types of issues to replicate this approach to know how to appropriately discount for their population.

6. More discussion regarding the policy implications of their findings would be important for the use of the methodology in health policymaking.

7. The English should be improved.
