Mayor Bill de Blasio announced on Monday that New York City's 488 public high schools will reopen for some in-person classes on March 22, after months of distance learning.

Why it matters: It's a key pandemic milestone for the biggest public school system in the country, which is made up largely of low-income and minority students, according to the New York Times.

The COVID Tracking Project, a volunteer group of data analysts, researchers, and journalists brought together by The Atlantic, published its final daily update on Monday — the one-year anniversary of its founding.

Why it matters: The project quickly became a vital resource for news media, academic researchers, and everyday Americans to track COVID-19 cases, hospitalizations, and deaths in the absence of reliable and public data from the federal government.

Colorado is shifting the focus of its COVID-19 vaccine distribution to equity now that supply is increasing.

Why it matters: The new approach is designed to reach racial minorities hit hard by the coronavirus and rural areas with less access to care.

Minnesota is now releasing COVID-19 vaccination data by race and ethnicity — and there's work to be done to achieve equity in distribution.

Florida Gov. Ron DeSantis said "the state was not involved" in helping to vaccinate 1,200 residents of the super-rich Ocean Reef community in January.

• But both the hospital system that supplied the doses and Monroe County have contradicted his claims, saying the state authorized the vaccines, the Tampa Bay Times and Miami Herald report.

Why it matters: DeSantis has faced increasing criticism for directing vaccines toward wealthy communities.

Some large employers are receiving permission from public health officials to vaccinate their employees at work, the Wall Street Journal reports.

Why it matters: This could remove barriers to getting the vaccine for some workers in high-risk industries. But it also increases the competition for shots while they're still scarce.

When Tampa's Barbara Thomas signed up to get her COVID-19 vaccine, she didn't think she'd be getting the shot six days after the virus killed her husband, Larry.

Why it matters: Her story is similarly playing out for hundreds of thousands of families nationwide who can never truly have a return to normal without those lost during the pandemic.

The verdict from Americans trying to get the COVID vaccine is in: the sign-up websites are awful.

Why it matters: Appointment systems are a vital part of getting Americans vaccinated, but a series of missed opportunities, at every level, left local governments scrambling. And the frustrating, confusing process now carries the risk that some people will simply give up.

Pfizer CEO Albert Bourla tells "Axios on HBO" that he recently received his first of two doses of the company's coronavirus vaccine.

Pfizer CEO Albert Bourla told "Axios on HBO" that it "will be terrible for society" if the price of coronavirus vaccines ever prohibits some people from taking them.

Why it matters: Widespread uptake of the vaccine — which might require annual booster shots — will reduce the risk of the virus continuing to spread and mutate, but it's unclear who will pay for future shots or how much they'll cost.

Mississippi Gov. Tate Reeves (R) defended his decision to revoke the state's mask mandate on CNN's "State of the Union" Sunday, describing the move as backed by data and a necessary step to boost the state's economy.

Why it matters: Although hospitalizations have dropped, Mississippi had the largest increase in the average of new coronavirus cases over a seven-day period in the country as of March 2, according to Axios' weekly tracker.
