    Model Structure: Using Microsoft Excel (Microsoft Corporation, Redmond, WA) with the Crystal Ball add-in (Oracle Corporation, Redwood Shore, CA), we developed a computational model (in 2020) representing the U.S. population (357,157,434 persons) and their different interactions with each other as well as the spread of SARS-CoV-2 and the potential health and economic outcomes7.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Limitations: All models, by definition, are simplifications of real-life and cannot account for every possible outcome.29 Our model inputs drew from various sources, and new data on SARS-CoV2 continues to emerge. The course of an actual COVID-19 coronavirus epidemic may not conform to our model data and assumptions. For example, we assumed individuals mixed equally with each other, and that individuals would be vaccinated by a certain day during the epidemic; however, in reality, individuals may be vaccinated at different time points over the epidemic. Moreover, assumptions about levels of herd immunity required may depend on differing individual susceptibility to SARS-CoV-2. Conclusions: Our study found that to either prevent or largely extinguish an epidemic without any other measures (e.g., social distancing), the vaccine has to have an efficacy of at least 70% when vaccination occurs within 90 days of the start of the epidemic and covers at least 60% of the population. This efficacy threshold increases the deeper one goes into the pandemic. A vaccine with an efficacy between 40% and 70% can still obviate the need for other measures under certain circumstances such as much higher, and potentially unachievable, vaccination coverages.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
