The United States was one step away from vaccinating a million people against the coronavirus

As of Thursday, 154 million vaccines had been administered. President Joe Biden’s new goal is to apply 200 million doses during his first 100 days in office.

But coronavirus cases are on the rise again, and authorities have warned they could ban fans from visiting baseball stadiums if the numbers continue to rise. Even before the major league season began, one of the opening day games was postponed due to one player testing positive.

The Washington Nationals were scheduled to host the New York Mets on Thursday night, but after one of their players tested positive, the U.S. capital team called the game off.

In Chicago, authorities have warned that if cases continue to rise, they will not allow fans to enter Wrigley Field or Fixed Rate Field, or bars and restaurants.

The warning was included in a press release issued by the city’s Office of Emergency Management and Communications the day before the Chicago Cubs’ first game of the season. Both stadiums will have a 25% capacity when they reopen for the first time since 2019.

For Wrigley Field, that means there will be over 10,000 fans in the stands. Many more are expected to attend the rally from nearby bars and restaurants. The guaranteed rate field houses the White Sox.
