The Garden announced today that starting Sept. 30, everybody attending a game or event there will have to show proof of Covid-19 vaccination or a recent negative test.
Children under 12 don't have to show either. However, everybody will have to wear a mask inside. Also: Don't try showing results from an at-home test - only results from tests administered at clinics, pharmacies and the like will be accepted. The Garden adds you a photo on your phone of your vaccinations will do the trick, providing it's been at least two weeks since your final shot.
