A coronavirus vaccine from Oxford University and AstraZeneca, perhaps the most promising candidate currently in development, appears to be safe and produces an immune response, according to preliminary findings published in The Lancet.

Why it matters: The race is on to get a vaccine approved and into circulation. A separate report published today finds that a Chinese candidate also produces an immune response, while American biotech firm Moderna revealed last week that its candidate produces a strong immune response.

State of play: The Oxford vaccine is in phase three trials, the last step before possible approval. According to the Economist, it could be cleared for emergency use as early as October.

  • Moderna's vaccine is moving into phase three now, while another candidate from Pfizer is believed to be relatively close behind.
  • China has at least six candidates currently in trials, one of which is in phase three.
  • Russia says a candidate from its state-run Gamaleya Institute will enter phase three trials next month.
  • According to the Milken Institute's tracker, there are 197 candidate vaccines in development, 19 of which are in some stage of clinical trials.

What to watch: While it seems increasingly likely that a vaccine will be available by early next year — the timeline suggested by Anthony Fauci — it remains unclear who will get it first.

  • The U.K. announced today that it had bought up millions of doses not only of the Oxford vaccine, but of candidates from France and Germany.
  • That's another sign that this could play out as a bidding war, rather than the sort of equitable distribution European leaders have discussed.
  • President Trump, meanwhile, has at times described the vaccine race in America First terms. The U.S. is pouring billions of dollars into developing and manufacturing vaccines and expects to claim millions of doses if and when they are approved.

Facebook removed a video post from President Trump Wednesday in which he claimed in an interview with Fox News that children are "almost immune" to COVID-19.

Why it matters: It’s the first time that Facebook has removed content from Trump's account for violating policies on coronavirus-related misinformation.

Fauci: Coronavirus task force to examine aerosolized spread

The White House coronavirus task force will examine more closely just how much SARS-CoV-2 might be transmitted via aerosols, and not just from droplets, NIAID director Anthony Fauci said Wednesday at an online forum sponsored by Harvard T.H. Chan School of Public Health.

Why it matters: The longer the coronavirus can remain infectious in the air, the more likely it can infect people, particularly indoors — leading to the possible need to alter air filtration and circulation within buildings.

The Philippines' economy sunk into recession as its gross domestic product shrank 16.5% in the second quarter — marking the lowest reading since 1981, official figures show.

The big picture: Millions of Filipinos went on lockdown Tuesday as cases surged past 106,300, with stay-at-home orders in place for two weeks in Manila and nearby provinces on the island of Luzon, per the BBC. The economy's contraction is the "deepest" on record, Bloomberg notes.
