Russia's Sputnik V vaccine demonstrated nearly 92% efficacy against symptomatic cases of COVID-19 and provided complete protection against severe cases, according to a peer-reviewed analysis of a large clinical trial published in the medical journal the Lancet. The vaccine also appears to be safe.

Why it matters: This is the strongest evidence to date that the Russian vaccine is one of several highly-effective options in the global mix. Russia is almost entirely dependent on Sputnik V to vaccinate its own population, and over a dozen other countries have purchased doses.

  • That number is likely to continue to rise, though Russia has thus far struggled to ramp up its manufacturing capacity.
  • Russia hopes to vaccinate 60% of its population by year's end, per WSJ.

Flashback: Vladimir Putin announced in August that the vaccine had been approved despite very limited data, and then in November the state-run Gamaleya Research Institute claimed it was 92% effective, without initially providing supporting data.

  • Both announcements were met with a great deal of international skepticism. But those doubts will be at least partially assuaged by the findings released on Tuesday.

A massive uncontained bushfire has destroyed at least 30 homes in the Perth Hills, Western Australia, officials told the Australian Broadcasting corporation Tuesday.

Why it matters: Per state Premier Mark McGowan, "Right now WA is battling two different kinds of emergencies — a dangerous fire emergency and a COVID-19 lockdown emergency." He said there are "threats to lives and homes" from the wildfire.

COVID time warp

The start of the COVID-19 pandemic seems like a lifetime ago to some, and just yesterday to others. Scientists are beginning to unpack the way people processed the passage of time amidst the stress, uncertainty and isolation of the 1 year, 8 months and 21 days since WHO declared a pandemic.

Why it matters: The pandemic's global effects on how people experience time could provide new insights into the brain's ability to perceive and predict time — a fundamental feature of life.
