The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented. Reviewer #1: No Reviewer #2: Partly ********** 2. Has the statistical analysis been performed appropriately and rigorously? Reviewer #1: No Reviewer #2: Yes ********** 3. Have the authors made all data underlying the findings in their manuscript fully available? The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). 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. Reviewer #1: Yes Reviewer #2: Yes ********** 4. Is the manuscript presented in an intelligible fashion and written in standard English? PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous.

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: This is an interesting study with value to add to current literature. The study design is technically sound. My major concern is that causative conclusions are drawn without robust statistical analysis to support them. There is insufficient discussion of the potential limitations of the study, particularly concerning is the absence of discussion of confounding factors that may have contributed to the reduction in frequency of rotavirus infections. Further details on sampling and recruitment methods would also be beneficial - was a sample size calculation performed? Overall, there are some errors in spelling (importantly faces -> faeces/feces) and grammar that should be addressed to make the manuscript clearer. Reviewer #2: The authors used a case-control study design to indirectly evaluate rotavirus vaccine efficacy in hospital admitted diarrhea patients in Rwanda. They compared rotavirus and other enteric pathogen detection rates in patient samples collected before and after vaccination campaign with Rotataq. The hypothesis is that if the rotavirus vaccine is effective relative proportions of rotavirus infection should be lower and other enteric pathogens should be higher in samples collected after vaccination campaign. The limitation of the paper is that because of the case-control design nature, efficacy was measured as odds ratio while number of previously published studies, including prospective studies in countries of similar economic status demonstrated vaccine protective rates. This study does not offer any significant novel findings. The other objective of the study is to investigate the rotavirus serotype shifts after vaccination with Rotataq. However, given the short period of observation and small sample size, the authors are unlikely to distinguish if the viral serotype changes are the result of vaccination or natural variation. There are other issues the authors need to address. 1. The authors used pre and post vaccination hospital admitted diarrhea patients to compare the RV infection rates in several age groups. There was not significant protection in age 12-36 month group and the overall odds ratio was moderate in age <12 month (table 2). Their results are consistent with previously reported moderate efficacy of rotavirus vaccine in low income developing countries including African countries. Because of the differences in age groups, the authors should provide more details of Rwanda rotavirus vaccine program. For instance, the vaccination starting age and how many boost immunizations and the vaccination rate in different age groups. The author should discuss if the different vaccine protective efficiency in the two age groups are the results of vaccination schedule or vaccination rate. 2. Table 1, 2, it appears that group of >36 month old had no specific values in the study. Authors should consider to remove this age group from the analysis. 3. Table S1, authors suggested that the rotavirus vaccine worked better to prevent severe dehydrating diarrhea. Since it is one of their major conclusions, the table S1 should be included in main text. Odds ratios for severe diarrhea in rotavirus positive and negative groups should be separately calculated and age difference in vaccine effect on severe diarrheal disease should also be examined and results should be discussed. 4. It is not clear what is the difference between fig. 1A and 1B. There is no specific mention of fig 1A and 1B in the result section. Please clarify. 5. It is reasonable to assume that if the rotavirus vaccine is effective, the proportion of other enteric pathogens in diarrhea patients should increase. However, the authors need to explain more the assumption in line 16 that higher frequencies of other pathogens in combination with rotavirus infection. 6. The authors should provide summary table and related statistics to show increased other enteric pathogen infection after rotavirus vaccination. 7. In figure 1, the authors showed high infection rates and odds ratios for some of the no-rotavirus enteric pathogens in in rotavirus infected and vaccinated patients. Do authors suggest that rotavirus vaccination increased risk of other enteric infection especially in rotavirus infected patients? Can authors provide hypothesis and references (if any) for the increased rotavirus coinfection with other enteric pathogens after vaccination? 8. The other major objective for the paper is to investigate serotype shit in field rotavirus strains as the result of vaccination pressure. The results were inconclusive. The authors please explain given the duration of the study and the number of samples, what expected of rotavirus serotype changes will be considered as the definite conclusion that rotavirus vaccination significantly alter the serotype of epidemic rotavirus strains? ********** 6.
