All participants in this year's Macy’s Thanksgiving Day Parade must be vaccinated and wear face coverings, the department store announced Wednesday. Singers, dancers and musicians may be exempt from wearing face masks.

The number of participants will see a 10 to 20% cut this year and social distancing will be followed, Macy's added.

Last year, much of the parade was pre-taped due to the pandemic. There were no high school band performances and limited spectators on the street.

The marching band and other specialty group performances that were initially set to perform last year will get to participate in this Thanksgiving's parade, Macy's said.

The Supreme Court will resume in-person oral arguments on Oct. 4 for the first time since the pandemic began.

All arguments will be in person from Oct. 4 through the rest of the year. The courtroom will only have staff, counsel of cases on the docket and hard-pass court reporters there in person, with the court staying closed to the general public.

The court says it will continue to offer a real-time live audio feed of arguments.

Just 20% of people in low and lower-middle-income countries have received their first vaccine dose, compared to 80% of people in high and upper-middle income countries, according to the World Health Organization and COVAX, the initiative aiming to provide equitable vaccine access across the world.

"The global picture of access to COVID-19 vaccines is unacceptable," COVAX said, adding that its ability to reach lower income countries is "hampered by export bans, the prioritisation of bilateral deals by manufacturers and countries, ongoing challenges in scaling up production by some key producers, and delays in filing for regulatory approval."

COVAX said it expects to have access to 1.425 billion doses of vaccine this year, with about 1.2 billion available for lower income economies participating in COVAX's Advance Market Commitment.

"This is enough to protect 20% of the population, or 40% of all adults, in all 92 AMC economies with the exception of India. Over 200 million doses will be allocated to self-financing participants," COVAX said. "The key COVAX milestone of two billion doses released for delivery is now expected to be reached in the first quarter of 2022."

The United States has recorded more than 40 million confirmed cases of COVID-19, including over 650,000 deaths, since the start of the pandemic, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.

The U.S. surpassed the grim milestone on Tuesday, as the highly contagious delta variant continued to spread across the nation. The U.S. has reported more COVID-19 cases and deaths than any other country in the world.

The daily death average in the U.S. has climbed to about 1,100, which is a 65.5% jump in the last month, according to federal data.

The daily case average in the U.S. is around 140,000, which is nearly four times higher than it was one year ago, according to federal data.

South Carolina and Kentucky have the highest case rate in the nation, followed by West Virginia, Wyoming, Alaska, Alabama, Georgia and Mississippi, according to federal data.

But some states are seeing progress. In Florida, daily cases are down by about 33% in the last two weeks.
