Here's the latest on the pandemic from around the world overnight.

Britain's top medical advisers have recommended that all 12 to 15-year-olds receive a single dose of a COVID vaccine because "the benefits exceeds the risk by a small margin". Second doses would not be offered to the age group until at least spring as they would wait for data to build up internationally.
People who were fully vaccinated accounted for just 1.2 percent of all deaths involving COVID in England in the first seven months of this year

Slovenia will, from this week, require that all people who enter indoor spaces, with few exceptions, be vaccinated against COVID-19 or show negative tests unless they have had the disease in the previous six months.
India is worried that growing complacency as infection rates and deaths decline could lead to people skipping their second vaccine shots, leaving communities vulnerable to the virus, said two health experts briefed on the matter.
India reported 27,254 new coronavirus infections and 219 deaths.
The government of Australia's New South Wales said the pace of vaccinations had slowed as first-dose coverage neared 80 percent and urged the unvaccinated to get shots soon or risk missing out on freedoms when curbs ease.
The Philippines' capital region will shift to localised lockdowns and an alert level system starting September 16 to prevent the spread of coronavirus while allowing more businesses to resume operations, the president's spokesperson said late on Monday.
Wide-scale, strict and lengthy lockdowns since last year have decimated the Philippine economy, which was one of Asia's fastest growing before the pandemic.
The rapid pace of new COVID-19 infections and a doubling of seriously ill patients in Singapore have raised unexpected hurdles to reopening plans for the vaccination frontrunner, where 81 percent of the population is fully vaccinated.

South Africa will ease restrictions and shorten its nationwide curfew after a decline in infections, President Cyril Ramaphosa said in a televised address.
