11:18 a.m. South Korea extends its strictest social distancing rules in Greater Seoul for another four weeks. But health authorities will allow up to eight family members to gather during the Chuseok holidays later this month, if four or more of them have completed their inoculations.
10:30 a.m. New Zealand reports 28 new cases, down from 49 a day earlier and 75 on Wednesday, as authorities say the country is breaking the chain of transmission of the highly infectious delta variant. Of the cases reported on Friday, 27 were in Auckland and one was in Wellington.
5:30 a.m. The U.S. plans to invest $3 billion in the vaccine supply chain as it continues to work to position itself as a leading supplier of vaccines for the world, White House COVID adviser Jeffrey Zients says. The funding, which will start being distributed in the coming weeks, will focus on manufacturers of the inputs used in COVID-19 vaccine production, as well as facilities that fill and package vaccine vials, he said. Areas of focus will include lipids, bioreactor bags, tubing, needles, syringes, and personal protective equipment.
2:30 a.m. The European Centre for Disease Prevention and Control says there is no urgent need for booster doses of COVID-19 vaccines for the fully vaccinated, citing data on the effectiveness of shots.
The comments follow a similar statement from the European Medicines Agency last month that more data is needed to recommend using booster shots.
1:30 a.m. Cases of breakthrough infections are extremely rare among fully vaccinated people and their risk of experiencing lingering symptoms in what is known as "long COVID" is reduce by almost half, a new study finds.
The study, published in Lancet Infectious Diseases on Wednesday, covered nearly 1 million fully vaccinated British adults.
The study suggests that vaccinations not only protect people against severe COVID-19 symptoms and reduce the risk of hospitalization, but also significantly reduce the likelihood of experiencing lingering symptoms after an infection.

4:00 a.m. The virus behind COVID-19 continues to evolve, with scientists in South Africa reporting "mutations of concern" in a new variant first identified in May.
The so-called C.1.2 lineage has been detected across most South African provinces and in seven other countries spanning Africa, Europe, Asia and Oceania, the researchers write in an early version of a paper. They do not yet know whether the mutations make the virus more contagious or more resistant to immunity from vaccines or infection, Reuters reports.
3:45 a.m. New Zealand has announced checkpoints on the outskirts of Auckland, the nation's largest city, to question drivers in the name of preventing nonessential movement between regions.
