In accordance with the City of Springfield's most recent guidance, there will no longer be a mask mandate at Thunderbirds games, effective March 1, 2022.

From the City of Springfield's press release:

Mayor Domenic J. Sarno states, “After reviewing the recent COVID-19 trends with Commissioner Helen Caulton-Harris, we are happy to report that we have seen five consecutive weeks of a significant decrease in COVID-19 cases.  Based on this news, our citywide vaccination rates steadily increasing and the positive trends we are seeing, Commissioner Caulton-Harris and I are confident that we can let this citywide mask mandate expire on Monday, February 28, 2022.  We have all worked so hard and our efforts have worked in mitigating the spread of COVID-19.  It is important not to ostracize anyone who wishes to continue to wear a mask when this mask mandate expires, as they may feel safe wearing them still and/or they may have a compromised immune system.”
