Reviewer 2 Report
Q1. Introduction, lines 23-40. One of the main problem of those days was the absence of a causality assessment that would have justified the suspension (or not) of the vaccine. Please revise
Q2. Introduction, lines 64-73. Please cite this Italian study https://pubmed.ncbi.nlm.nih.gov/35107123/
Q3. Methods, line 134. It is not clear to me how did you weight the data to reach the desired quotas
Q4. Conclusions. Please add a small paragraph on vaccine hesitancy in subgroups of population, as healthcare workers, and its impact on vaccination campaign
Author Response
Thank you for your feedbacks. We have addressed the issues you kindly pointed out.
Q1: added a statement to clarify this important aspect
Q2: this reference was not included at first since the article was published only a few days before the submission of this manuscript. However, given its relevance for our paper, we have included it, thank you for pointing it out
Q3: sampling weights is a strategy employed to make sure that quotas form a planned stratified sampling are reached. In fact, due to non-response and self-selection bias, stratified sampling oftentimes fails to reach the exact desired quotas: weighting compensates for this by assigning to each subject a value which is the reciprocal of the likelihood of being sampled. In our case, sampling weights were provided by the panel provider which was in charge of the stratified sample. We have added a sentence to methods to make sure that readers understand how sampling weights work.
Q4: we have revised our discussion to include further details on vaccine hesitancy in different population subgroups
