<h3>Abstract</h3> Four U.S. National Football League teams required vaccination certification against the SARS-CoV-2 virus of attendees at home games during 2021 season. Using daily data on confirmed cases and vaccinations in counties surrounding these stadiums that did not require certification, this study estimates effects policy. Ordinary least squares regression was used to estimate change community spread after away relative weeks play (bye weeks). Compared metropolitan areas near with no requirement, had a requirement significantly less 14 days games. In six leading up beginning season, percent vaccinated increased were requiring only if prevalent preseason rate relatively low. Required venues for large gatherings appear slow generally nearby communities increases percentages lower percentages.
