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.

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.

Leading public health officials lay out plan for boosters
The U.S. is prepared to offer booster shots for all Americans beginning the week of Sept. 20, top health officials announced Wednesday. Starting eight months after a person's second dose, they are eligible for a booster.
"At that time, the individuals who were fully vaccinated earliest in the vaccination rollout, including many health care providers, nursing home residents, and other seniors, will likely be eligible," Rochelle Walensky, director of the CDC; Janet Woodcock, acting FDA commissioner; Dr. Vivek Murthy, surgeon general; Francis Collins, director of the NIH; and Anthony Fauci, director of the NIAID, said in a joint statement.
The data behind the decision is expected to be released at 11 a.m. EST during the White House COVID briefing, but public health officials said it's clear that vaccines are waning over time and "we are starting to see evidence of reduced protection against mild and moderate disease."
With regard to the Johnson & Johnson vaccine, officials stressed that more data will be released in the next few weeks. "We will keep the public informed with a timely plan for J&J booster shots," they said.
