Pandemic aid stalled in the Senate and Shanghai remained in lockdown: The week in Covid news.

The federal government has run out of money to cover coronavirus vaccines, testing and treatment for uninsured Americans, but Congress has yet to approve additional funding for the pandemic response. A bill that would allocate $10 billion for these purposes was stalled on Tuesday when Senate Republicans refused to advance it without a vote to keep in place pandemic-era border restrictions that President Biden has decided to lift. .

Congress is now on a two-week hiatus, so the impasse means final passage of the aid the Biden administration has declared urgently needed will stretch through at least the last week of this month. . The package will not include a $5 billion proposal for the fight against the global pandemic, which senators could not agree on.

A federal fund set up to reimburse doctors for caring for uninsured Covid patients stopped accepting claims in late March. On Wednesday, it stopped reimbursing providers for vaccinating uninsured people.

Without federal funding, major testing sites and labs like Quest Diagnostics charge $100 or more for testing, and smaller services could shut down altogether, just as states close mass testing sites. On Tuesday, Embry Health, a leading testing provider in Arizona, said it would suspend operations at 60 sites in the state and no longer offer free testing to uninsured people.

  • A second booster shot of the Pfizer-BioNTech vaccine provides additional short-term protection against Omicron infections and serious illnesses in the elderly, according to a new large study from Israel.

  • Dr. Rochelle P. Walensky, director of the Centers for Disease Control and Prevention, said Tuesday that her agency would “really encourage people over 50 who have underlying medical conditions and those over 65” to get a second reminder. shoot. European regulators said on Wednesday it was “too early” to administer a second booster to the general European Union population, but added that the additional doses could be given to adults aged 80 and over. more.

  • A federal appeals court on Thursday overturned a ruling that had prevented the White House from requiring federal workers to be vaccinated against the coronavirus.
