Moderna announced Monday that it has begun testing on a potentially refrigerator-stable version of its coronavirus vaccine.

Why it matters: Moderna's "next generation COVID-19 vaccine," if found to be effective, could be handled by ordinary pharmacies that aren't equipped with ultra-low freezers, which have been an impediment in the vaccine rollout.

  • Moderna's current coronavirus vaccine must be stored at -20°C after being kept at standard refrigeration for 30 days prior to use.
  • Pfizer announced last month that its vaccine could be stored for two weeks at standard temperatures. Johnson & Johnson's one-dose vaccine, the third shot authorized for emergency use by the FDA, can also be stored at routine refrigerator temperatures.

What they're saying: Moderna CEO Stéphane Bancel said in a press release that the vaccine "could facilitate easier distribution and administration in a wider range of settings, including potentially for developing countries."

Russian President Vladimir Putin said Wednesday that his summit with President Biden was "constructive," and that the countries had agreed their ambassadors would imminently return to their posts in Moscow and Washington.

What he's saying: "Many of our joint positions are divergent but nevertheless I think both sides manifested a determination to try and understand each other and try and converge our positions," Putin told reporters at a press conference immediately following the meetings, according to a translator.

Live updates: Putin holds press conference after Biden summit concludes

President Biden met with Russian President Vladimir Putin in Geneva for less than four hours of talks on Wednesday, a highly anticipated summit that comes as both sides say U.S.-Russia relations have sunk to a new post-Cold War low.

The latest: The summit concluded at about 11:15 a.m. ET, according to the White House. At a press conference, Putin called the talks "very constructive' and announced that the U.S. and Russia's respective ambassadors would return to their posts. Biden is expected to deliver his own press conference at 1:30 p.m. ET.

Southwest heat wave intensifies, breaks records and worsens drought

A punishing and long-enduring heat wave is intensifying in parts of the West and Southwest, with heat warnings and advisories in effect across seven states Wednesday. The heat will not relent until late in the weekend.

Threat level: In the coming days, 40 million are likely to see temperatures reach or exceed 100 degrees.
