A group small businesses in New York City is suing the city on the grounds that its new indoor vaccine mandate will severely impact their "business, life savings, and livelihood," according to a lawsuit filed in Richmond County Supreme Court Tuesday.

The plaintiffs also took issue with the fact the the mandate does not permit medical or religious exemptions to COVID-19 vaccination.

New York City's first-in-the-nation mandate, which went into effect Tuesday, applies to everyone 12 and older and includes nearly every public indoor activity, from gyms to bowling alleys to movie theaters to concert venues and more, according to the city.

The plaintiffs include Deluca’s Italian Restaurant in Staten Island, Pasticceria Rocco in Brooklyn and Staten Island Judo Jujitsu.

All but two states -- New Hampshire and Vermont -- are reporting high community transmission, according to federal data.

U.S. hospitalizations are now at the highest point in over six months, with more than 91,000 COVID-19 patients currently in hospitals, according to federal data. More than 11,200 patients are being admitted to the hospital each day, the most since January.

Pediatric COVID-19 related admissions per capita have climbed to the highest point of the pandemic and are now nearly six times higher than on July 4.

U.S. Surgeon General Vivek Murthy announced at Wednesday's White House briefing, "Having reviewed the most current data, it is now our clinical judgment that the time to lay out a plan for COVID-19 boosters is now."

Murthy said protection against mild disease has decreased, likely a combination of waning vaccine protection over time and the strength of the delta variant, and that the administration is "concerned" that protection could continue to erode.

"Even though this new data affirms that vaccine protection remains high against the worst outcomes of COVID, we are concerned that this pattern of decline we're seeing will continue in the months ahead, which could lead to reduced protection against severe disease, hospitalization and death," Murthy said.

"That is why, today, we are announcing our plan to stay ahead of this virus by being prepared to offer COVID-19 booster shots to fully vaccinated adults 18 years and older," Murthy said. "They would be eligible for their booster shot eight months after receiving their second dose of the Pfizer or Modern mRNA vaccines."

The boosters are set to begin Sept. 20, but Murthy emphasized that this is pending FDA authorization and also reiterated that does not yet apply to J&J recipients.

New York City botched its COVID-19 response, according to an investigation conducted by Scott Stringer, the city's comptroller, who released findings from his inquiry Wednesday.

According to Stringer, key emergency response agencies, including the health department and the NYPD, were intentionally excluded from communications and decision-making "when time was of the essence."

The comptroller also described persistent confusion about the chain of command between agencies and a significantly delayed response to the pandemic.

Officials waited until late February to even begin planning for a worst-case scenario, despite knowing about the impending crisis in January. Stringer called on the mayor, as well as the future mayor, to conduct a thorough review of the city's emergency planning process.

"We cannot erase the mistakes of the past," he said. "But we can make sure we are prepared for future emergencies."

New Zealand's first instance of COVID-19 transmission in six months has been identified as the highly contagious delta variant.

"We are dealing with a delta variant," New Zealand Prime Minister Jacinda Ardern announced during a press conference in Wellington on Wednesday. "Our case has originated in Australia."

The case, which was detected in the community on Tuesday, prompted New Zealand to immediately impose a nationwide lockdown. More community cases have emerged since then, with the cluster growing to 10 by Wednesday afternoon, according to data from New Zealand's Ministry of Health.

Ardern said genomic sequencing has linked the initial case to an outbreak of the delta variant in neighboring Australia's New South Wales state.

"Now, the job we have is to work through how and when it got here," she said.

It's the first time that the island nation of 5 million people has confirmed the presence of the delta variant, which was initially identified in India last October. At least 148 countries around the globe have reported cases of the delta variant, according to the World Health Organization.

It's also the first time in more than a year that New Zealand has had a snap level four lockdown, the highest level of restrictions.

In total, the country has reported 2,936 confirmed cases of COVID-19 since the start of the pandemic, including 26 deaths, according to health ministry data.
