- Opening day between the Washington Nationals and the New York Mets postponed after a player tested positive for COVID. Elsewhere, Yankee Stadium opening up with temperature checks and proof of vaccination. And the Texas Rangers planning to open its ballpark at full capacity, a decision President Biden calls a mistake.

JOE BIDEN: They should listen to Dr. Fauci, and the scientists, and the experts. And-- but, I think it's not responsible.

- The president's words highlighting the current COVID surge. Cases up 17% in the last two weeks, with hospitalizations increasing in 20 states, now reaching 5,000 admissions a day, all while the US continues to see more variants spread.

Michigan now reporting the first confirmed case of the Brazilian variant, the state also seeing a sharp rise in hospitalizations. Dr. Fauci telling our station, WXYZ, the state opened up too soon.

ANTHONY FAUCI: The results, I think, are being manifested in what you're seeing in Michigan.

- As for the vaccines, more promising evidence. Pfizer saying its vaccine is still highly effective after six months. It also appears to work against the worrisome South African variant. And this morning, the FDA has given Moderna the OK to put 50% more doses in each vial.

Meanwhile, Johnson & Johnson saying they'll still deliver 100 million doses by the end of May even after the setback in a manufacturing plant where 15 million future doses were ruined. That's encouraging news for Ohio Governor Mike DeWine, who wanted to give J & J's single shot vaccine to every college student in his state.

MIKE DEWINE: It is a strategic move, frankly, to vaccinate them on campus before they get out.

- The CDC now says over 38% of Americans over the age of 18 have received at least one vaccine dose.
