Proof of full vaccination or negative COVID-19 test results will be required to enter certain festival grounds at the Milford Oyster Festival, organizers say.

Organizers say proof of full COVID-19 vaccination or proof of negative COVID-19 test received within the past 72 hours will be required to enter the main stage concert area in Fowler Field. They say amusement rides and children’s area in Fowler Field will also not be active this year.

Organizers say there will be two tent locations in Fowler Field to receive a wristband for entry into the Main Stage concert when proof is presented.

Fans outside the fence, near the beer and food tents, do not have to show proof of vaccination and can still listen to the music. Proof of vaccination is not required anywhere else at the festival.

The festival will take place on Saturday, Aug. 21, from 10:00 a.m. to 6:00 p.m.

One measure that's not mandatory is wearing a mask, but the city's health director is urging people to consider it.
