The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.

More than 620,000 Americans have died from COVID-19 and over 4.3 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.

Just 59.1% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

Moderna vaccine maintains antibodies against variants for at least 6 months: Study

People who received Moderna's COVID-19 vaccine still produced antibodies six months later against several variants of concern, including delta, a new study found. 

The study, which was published in the journal Science Wednesday, only looked at antibody response at least six months out. The antibody levels, which are one piece of the overall immune response, waned over time but they were still there after six months.

This study is part of a mounting body of evidence suggesting that vaccines are likely still to protect against new variants many months after initial vaccination. The Food and Drug Administration is expected to recommend booster shots for immune-compromised people this week.

No pediatric ICU beds in North Texas

There are no available pediatric intensive care unit beds in North Texas, hospital officials said Thursday, amid a "very serious fourth surge" of COVID-19.

There are 73 confirmed pediatric patients hospitalized in the region, "which is the highest level ever of pediatric COVID-19 patients we have ever treated," W. Stephen Love, president of the Dallas-Fort Worth Hospital Council, said in a report Thursday.

There are no staffed pediatric ICU beds available in the region as the children's hospitals also battle an unseasonably high number of RSV patients, Love said.

Florida, Hawaii, Louisiana, Mississippi reporting most cases ever

As the delta variant surges throughout the U.S., states including Florida, Hawaii, Louisiana and Mississippi are now averaging more daily cases than at any point in the pandemic.
