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

More than 630,000 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 60.2% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

Pfizer asks FDA for full booster dose approval

Pfizer on Wednesday asked the Food and Drug Administration for full approval for a booster dose. The company said its Phase 3 data showed that people who received a third dose between five to eight months after the second shot had antibody levels three times higher than levels seen after the second dose.

Because the Pfizer shots were approved by the FDA on Monday, Pfizer is now asking the agency to consider a “supplemental” application for boosters for people ages 16 and over. This is a “rolling submission,” with Pfizer intending to complete the submission by the end of the week.

The Biden administration said its goal is to have boosters available beginning Sept. 20, with the recommendation of getting one eight months after the second shot of Pfizer or Moderna.

Delta is raising health insurance premiums for unvaccinated employees by $200 a month to cover COVID-19 costs like potential hospitalization, which the airline says has cost it $40,000 per person on average.

Currently 75% of Delta employees are vaccinated, according to the airline.

The health insurance premium begins Nov. 1.

Unvaccinated employees will also have to wear masks indoors and be required to take a weekly COVID test beginning Sept. 12.

J&J says its vaccine booster shot raises antibody levels 9-fold

In the midst of a delta variant surge, a new study finds that giving a booster dose of the Johnson & Johnson shot six months after primary vaccination results in a nine-fold increase of a crucial antibody response, according to a company press release.

Meanwhile, a prior study found that people vaccinated with the Johnson & Johnson vaccine still had a durable immune response at least eight months later, even without a booster.

Collectively, the findings could help inform the U.S. government’s recommendations about booster shots for the 14 million people who received the single-shot Johnson & Johnson vaccine.

Boosting after six months “appears to be safe, and boosts immune responses substantially,” Dr. Dan Barouch, Ph.D., director of the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center, told ABC News.

“This is the additional extra layer of protection that we didn’t have a year ago,” she said.

Porter said she has been in discussions with the United Federation of Teachers over what the penalties will be if a teacher doesn’t comply, and she was told that “many of their members are already vaccinated.”

The chancellor said those who still have concerns should know that the Food and Drug Administration has fully approved the Pfizer vaccine and it has shown to prevent severe illness.
