Friday, Aug. 20
9:58 p.m. Vietnam authorities are deploying forces including the army to deal with COVID-19 outbreaks in the economic hub of Ho Chi Minh City and provinces in the south, ahead of the arrival of U.S. Vice President Kamala Harris, as deaths from the virus spiral.

The grim milestone comes just as President Rodrigo Duterte approved a recommendation to ease lockdown restrictions in Metro Manila from Saturday.
5:10 p.m. Tokyo reports 5,405 new cases, posting more than 5,000 for a third straight day, as Japan's capital struggles to ward off the delta variant. The seven-day average of new cases in Tokyo rose 13.6% from a week earlier to 4,721.
4:15 p.m. The U.K.'s health regulator has approved an antibody cocktail developed by Regeneron and Roche to prevent and treat COVID-19, it says, which it hopes to roll out soon.

Ronapreve can be taken via injection or infusion.
3:40 p.m. Vietnam's business hub, Ho Chi Minh City, says residents will be barred from leaving their homes, as the country's biggest city takes drastic measures to slow the spiraling rate of coronavirus deaths. Details of the order, which takes effect Monday, have yet to be announced. Vietnam has been slow to procure vaccines, having logged just 35 deaths and fewer than 3,000 cases as of May 1. But that has since jumped to over 312,000 cases and 7,150 deaths, with about half of the infections and 80% of fatalities in Ho Chi Minh City alone.
3:30 p.m. Japan's blue-chip Nikkei Stock Average fell 1% on Friday, closing at its lowest level this year.

11:00 a.m. New Zealand's COVID-19 outbreak widened beyond its largest city Auckland as new infections were discovered in the capital Wellington and case numbers jumped to 31. The findings meant Prime Minister Jacinda Ardern will most likely extend a nationwide lockdown that she announced this week to try and curb the spread of the highly contagious delta variant. Health authorities said 11 new cases were recorded on Friday, of which three were in Wellington.
10:45 a.m. China reports 33 new cases for Thursday, compared with 46 a day earlier. Of the new infections, four were locally transmitted, down from five a day earlier.

The current lockdown was due to end on Aug. 28.
9:00 a.m. Japan's core consumer prices fell 0.2% in July from a year earlier, government data shows, the 12th straight month of declines and a sign that the drop in demand due to the COVID-19 pandemic is keeping the economy under deflationary pressure. Japan's decision on Tuesday to extend emergency curbs into mid-September is expected to deal a further blow to household spending.
3:30 a.m. The Africa director at the World Health Organization criticizes decisions by some wealthy nations to start administering coronavirus booster shots.
"Moves by some countries globally to introduce booster shots threaten the promise of a brighter tomorrow for Africa," Matshidiso Moeti says in an online news conference. "As some richer countries hoard vaccines, they make a mockery of vaccine equity."
African countries lag far behind other regions in inoculations, with only 2% of the continent's 1.3 billion people fully vaccinated against COVID-19.
1:00 a.m. Philippine President Rodrigo Duterte has approved the easing of coronavirus curbs in the capital region from Aug. 21 to 31, his spokesman says, even as the country reported its second-highest daily number of COVID-19 infections.
The capital region will be placed under the second-strictest level of coronavirus restrictions, after being on tight lockdown since Aug. 6.

Malaysia Airlines said all active pilots and cabin crew members had received vaccines, as had 95% of Malaysia-based employees under a policy set in July.
10:40 a.m. New Zealand's COVID-19 outbreak has jumped to 21 cases, but the authorities linked the origin of the virus to a recent Sydney returnee and said it may not have been in the community for long. There were 11 new cases in the last 24 hours. Prime Minister Jacinda Ardern said genome sequencing revealed that the current positive cases were a close match to a returnee from Sydney who arrived on a flight on Aug. 7. Ardern put the nation under lockdown after one new case was reported in its largest city, Auckland, the country's first in six months.
10:25 a.m. The U.S. Transportation Department says it will limit some flights from Chinese carriers to 40% passenger capacity for four weeks, after the Chinese government imposed similar limits on four United Airlines flights.

8:10 a.m. A British study has found that protection from the two most commonly used COVID-19 vaccines -- from Pfizer and AstraZeneca -- against the delta variant weakens within three months. Based on more than 3 million nose and throat swabs, the Oxford University study found that 90 days after a second shot of the Pfizer or Astrazeneca vaccine, their efficacy in preventing infections had slipped to 75% and 61%, respectively, from 85% and 68% two weeks after a second dose.
1:35 a.m. The U.S. plans to make COVID-19 vaccine booster shots widely available starting on Sept. 20, citing data that vaccine protection diminishes over time.
A third shot will be administered to people who received the two-dose Moderna or Pfizer-BioNTech vaccines at least eight months ago. Those who received the single-dose Johnson & Johnson shot are also expected to need boosters.
The booster shots initially will focus upon health care workers, nursing home residents and older people, among the first groups to be vaccinated, according to top U.S. health officials.

3:30 p.m. Asian countries are increasingly counting on COVID-19 vaccination certificates to normalize international business travel, which has all but dried up due to the pandemic. However, the rapid spread of the delta variant has added to the difficulty of coming up with common entry standards, given differences in vaccination rates and public health capacities in Asia. This highlights the challenge of opening borders and exempting travelers from quarantines through European-style "vaccine passports."
2:30 p.m. The number of COVID-19 patients in serious condition in Japan rose to 1,646 as of Monday from 1,603 a day earlier, hitting a record high for a fifth straight day, as the government struggles to stop the rapid increase in infections, led by the delta variant.

3:50 p.m. Taiwan has rejected an application for the production and emergency use of UBI Pharma's vaccine candidate in a setback for the island's push to attain self-sufficiency. Developing its own vaccine has been a major goal, though Taiwan has also ordered millions of shots from Moderna and AstraZeneca, and next week is due to start injecting its first domestically developed vaccine, made by Medigen Vaccine Biologics. The health ministry, explaining the rejection of emergency use authorization, said the antibodies engendered by UBI's vaccine candidate did not match with those prompted by the AstraZeneca vaccine.
