San Francisco City Attorney Dennis Herrera announced last week he was taking the dramatic step of suing the city’s own school district, which has kept its classrooms closed nearly a year. In the motion filed Thursday in San Francisco Superior Court, Herrera included alarming testimony from hospitals in the San Francisco Bay Area, doctors and parents on the emotional and mental harms of extended distance learning. San Francisco’s 52,000 public school students have been out of classes since March. Public health officials have allowed city schools to reopen since September but the district and teachers unions have not been able to finalize a deal on reopening classrooms.

State Health Commissioner Dr. Howard Zucker turned down the idea Thursday. He says, “The trend is favorable, but the situation is still very, very bad.”Spain has administered 1.67 million vaccine doses, with more than 586,000 people getting both doses. Ad___TEHRAN, Iran — Iran has received its first batch of the Russian coronavirus vaccine. Iranian state TV quoted Tehran’s ambassador to Russia, Kazem Jalali, as saying Iran has ordered 5 million doses from Russia.

Teachers unions in many large school districts, including San Francisco, say they won’t go back to classrooms until they are vaccinated. “Not a single San Francisco public school student has set foot in their classroom in 327 days,” Herrera said at a news conference, calling it shameful and unlawful. While the vast majority of California’s public schools have been closed since March, San Francisco schools have been allowed to reopen since September. Since the start of the pandemic, San Francisco has been on the cutting edge of COVID-19 restrictions. Newsom sidestepped direct comment on the San Francisco lawsuit, saying everyone is on the same page and wants to reopen schools safely.
