The Latest on the effects of the coronavirus outbreak on sports around the world:

The Seattle Sounders say their entire first team roster and team support staff are fully vaccinated against COVID-19, and the team will begin offering vaccinations to eligible fans at home games beginning this Sunday against the LA Galaxy.

The Sounders said all eligible players and staff for the Tacoma Defiance, the club’s USL franchise, are also fully vaccinated.

“Vaccinating all players and support staff across both our first team and Tacoma Defiance groups is a major milestone for our club,” Sounders general manager Garth Lagerwey said. “Bringing everyone to this moment safely would not have been possible without a lot of focused and dedicated people, but, in particular, I want to recognize our exemplary medical staff for steering us through the past year.”

The team said it will partner with Virginia Mason Franciscan Health and the city of Seattle to offer either the one-shot Johnson & Johnson or two-shot Moderna vaccines to fans starting with this Sunday’s game. Vaccinations will be offered on a walk-up basis and be available to fans from the time gates open through the end of the match.

Fans will also be offered a voucher for a free hot dog inside the stadium after receiving their vaccination shot.
