Half of all Americans are now fully vaccinated against COVID-19, a White House official said Friday, as the Biden administration continues to urge people to get the shot amid a resurgence in infections across the country.

In a tweet, White House data director Cyrus Shahpar announced that 50 per cent of the total U.S. population whichincludesthose younger than 12 years old who are currently ineligible for the vaccineare fully vaccinated.

Shahpar, who noted that the seven-day average of newly vaccinatedpeople is up 11 per centfrom last week and 44 per centover the past two weeks, said,"Keep going!"

In recent days, the more contagious delta variant has sent new U.S. cases surging to 94,000 a day on average, a level not seen since mid-February.

Deaths per day have soared 75 per centin the past two weeks, climbing from an average of 244 to 426. The overall U.S. death toll stands at more than 615,000.

The vast majority of those now hospitalized with the virus are unvaccinated.

At a briefing on Friday, White House press secretary Jennifer Psaki saidthere have been "early discussions about a range of options" for new vaccine mandates for certain situations, such as domestic travellers and nursing home workers.

She added that the administration has "concern" about anti-mask, anti-vaccine mandate restrictions in some states.

"If you don't want to abide by public health guidelines, don't want to use your role as leaders, then you should get out of the way,"Psaki said in reference to some state legislators.

She applauded United Airlines' announcement that it will require U.S.-based employees to be vaccinated against COVID-19 by late October. The airlinejoins a growing number of corporations responding to a surge in coronavirus cases.

Meanwhile,the Black Hills of South Dakotawere roaringwith motorcycles and crowds on Fridayas the Sturgis Motorcycle Rally started amid a rise in COVID-19 cases in the state.

Organizers expect at least 700,000 people during the 10-day event. Public health experts and some locals worry the rally will again play host to coronavirus infections. Only about 46 per centof adults who live in the county that hosts Sturgis are fully vaccinated, according to the U.S. Centers for Disease Control and Prevention (CDC), compared with 60.6 per centnationwide.

Last year's rally transformed Sturgis, usually a quiet community of under 7,000 residents, into a travel hub comparable to a major U.S. city. Hundreds of rallygoers were infected, and a team of researchers from the CDCconcluded the event ended up looking like a "superspreader event."

In theAsia-Pacificregion,China recorded another 80 locally transmitted cases of COVID-19 on Friday, as the country seeks to control its widest flare-up since the original outbreak with a combination of lockdowns, mass testing and travel restrictions. Of the new cases, 58 were found in the eastern city of Yangzhou in Jiangsu province, where the highly contagious delta variant spread among airport workers in the provincial capital of Nanjing.

The update came as China's presidentpledged that two billion doses of COVID-19 vaccines would be supplied to the world through this year, increasing China's commitment as the largest exporter of the shots.The figure likely includes the 770 million doses China has already donated or exported, and it's not clear if it includes a COVAX agreement for Chinese producers to supply 550 million doses.

Hundreds of millions of Chinese shots, the vast majority of which are from Sinopharm and Sinovac, have already been administered to people in many countries aroundthe world. However, there are concerns about whether they protect adequately against the highly transmissible delta variant.

The Philippines placed its Manila capital region under a two-week lockdown on Friday as the Southeast Asian country's Health Ministry reported 10,623 new coronavirus cases, the largest single-day jump in infections for almost four months.
