The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 628,000 Americans have died from COVID-19 while over 4.4 million people have died from the disease worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 59.9% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

Biden administration ships 1st of 500 million vaccine doses to Rwanda
The Biden administration on Tuesday will ship the first 188,370 doses of a 500 million dose commitment of the Pfizer vaccine to Rwanda, according to a senior administration official. The 500 million dose pledge was announced at the G7 summit in June and the contract the U.S. negotiated with Pfizer identified late August as the goal for initial shipments.
The U.S. is also sending 300,000 additional U.S. surplus doses to Rwanda Tuesday, making this first total shipment 488,370. All the doses will be distributed through Covax, the World Health Organization's vaccine-sharing initiative.

US reports over 200,000 new cases in a day for 3rd time this month
There were 209,988 new cases of COVID-19 confirmed in the United States on Monday, according to a real-time count kept by Johns Hopkins University, although that data likely includes a backlog from the weekend.
This is the third time this month that the U.S. has reported more than 200,000 newly confirmed infections in a single day.
Many states are no longer reporting COVID-19 data daily. Single-day case totals, particularly early on in the week, may be skewed as a result of a backlog release of data.
mRNA vaccine efficacy dropped 'significantly' among nursing home residents: CDC
A new CDC analysis found that Pfizer and Moderna vaccine efficacy dropped "significantly" among nursing home residents from March to July, as the delta variant became the predominant strain in the United States.
Researchers analyzed weekly reports from thousands of nursing home facilities in the U.S. and found that mRNA vaccines were roughly 75% effective against preventing any infection in late winter/early spring of 2021, early in the mass vaccination rollout and prior to the emergence of the delta variant. By summer of this year, effectiveness against any infection had dropped to 53%.
Crucially, this doesn't mean vaccines aren't working for nursing home residents, but the significant drop in effectiveness from March to July may support the use of booster doses for them, according to the CDC report.
A second analysis found that the mRNA vaccines are holding up well against hospitalizations for COVID-19. The research, which was conducted across 21 U.S. hospitals, found that the Pfizer and Moderna vaccines remained between 84% and 86% effective against potential hospitalizations from March to July of this year. A third analysis, conducted in New York State, found that all three authorized vaccines remained more than 90% effective at preventing hospitalization from early May to late June.
