COVID-19 updates: White House press secretary Jen Psaki tests positive

While more than 1,100 Americans are still dying from COVID-19 each day, the U.S. daily death rate has been slowly falling in recent weeks.

And now, forecast models used by the U.S. Centers for Disease Control and Prevention are predicting that weekly death totals will likely continue to fall in the weeks to come, though thousands of Americans are still expected to die from the virus.

The model expects 18,000 more virus-related deaths to occur in the next two weeks, with a total of around 767,800 deaths recorded in the U.S. by Nov. 20.

The model also estimates that 14 states and territories have a greater than 50% chance of having more deaths in the next two weeks compared to the past two weeks.

After more than 18 months, Australia announced Wednesday that it will lift a ban on its own people from leaving the country without permission.

Starting Nov. 1, citizens and permanent residents of Australia who are fully vaccinated against COVID-19 will no longer require an exemption to travel abroad. Australia has imposed some of the world's strictest border rules amid the pandemic, which Home Affairs Minister Karen Andrews said has kept the country "free from widespread COVID transmission."

"The easing of these restrictions is possible thanks to our impressive national vaccination rates, and I thank all those who have done the right thing and rolled up their sleeve," Andrews said in a statement Wednesday.

While Australian citizens and permanent residents are currently the "first priority," Andrews said, more travel restrictions -- including for some foreigners -- will be relaxed as the national vaccination rate "continues to climb." As of Wednesday, nearly 75% of people aged 16 and over in the country are fully vaccinated against COVID-19, according to data posted by the Australian Department of Health.

"I look forward to further easing restrictions over coming weeks and months as more and more Australians become fully vaccinated," Andrews said. "Before the end of the year, we anticipate welcoming fully vaccinated skilled workers and international students."

Immunocompromised people may need a fourth dose of the vaccine, according to newly issued guidance from the U.S. Centers for Disease Control and Prevention.

Those patients may end up needing an additional shot six months after their third dose of the Moderna or Pfizer vaccines, the CDC said. The fourth dose can be of any of the three available vaccines, according to the agency.

This is in line with what the CDC has said before regarding immunocompromised adults. A third shot is considered necessary to establish vaccination for those patients and a boost would need to come six months later, according to the agency.

An advisory panel at the Food and Drug Administration voted Tuesday in support of the Pfizer vaccine for kids 5 ages 11.

Seventeen people voted "yes" and one person abstained.

Next, the FDA will make a decision. Then, the matter heads to the CDC's independent advisory panel to deliberate and vote next week, and after that, the CDC director is expected to make the final signoff.

The earliest shots could be in arms is the first week of November.
