Bloomberg - Evening Briefing - Waning virus protection

Pfizer says data from the U.S. and Israel suggests that the efficacy of the Covid-19 vaccine it manufactures with BioNTech wanes over time, and that a booster dose is safe and effective at warding off the virus and new variants. The company detailed its case in a presentation to be given outside advisers to the U.S. Food and Drug Administration. The panel is expected to make recommendations for whether more Americans should receive those shots. (Moderna reported similar news about its own vaccine). In Africa, headway is being made in efforts to secure more shots for a population in which less than 3.5% have been fully inoculated. For America, there’s a grim new data point once seen to be a worst case scenario: One out of every 500 Americans has died from Covid-19. The U.S. continues to lead the world in confirmed infections (41.5 million) and deaths (665,000), with the actual numbers likely much higher. Here’s the latest on the pandemic. — David E. Rovella

Bloomberg is tracking the coronavirus pandemic and the progress of global vaccination efforts.

U.S. President Joe Biden said California Governor Gavin Newsom’s victory in Tuesday’s recall election indicates that voters back tough rules to fight the coronavirus pandemic. “The fact that voters in both traditionally Democratic and traditionally Republican parts of the state rejected the recall shows that Americans are unifying behind taking these steps to get the pandemic behind us,” he said.

The vaccination rate in the U.S., however, has started to decline again. The drop is being led by the South and Central regions and is a reversal of what a month ago seemed like a hopeful trend for public health officials. Those areas are also where the delta variant has been doing the most damage.

Chinese authorities have told major lenders to China Evergrande Group not to expect interest payments due next week on bank loans, taking the cash-strapped developer a step closer to one of the nation’s biggest debt restructurings. 

Inflation in Canada accelerated to the fastest pace since 2003, a political headache for Prime Minister Justin Trudeau only five days before an election. The consumer price index rose 4.1% in August from a year earlier.

In 2015, Natalia Fishman-Bekmambetova arrived in Kazan, capital of the semi-autonomous Russian republic of Tatarstan, to oversee a large public works program. She found a city with a population of 1.7 million, a renowned university, grand boulevards and major historic sites. But Kazan also was a typical post-Soviet city—little attention had been devoted to revitalizing derelict public open spaces or to building new ones.

The new pedestrian promenade surrounding Kazan’s Kaban Lake features illuminated benches.
