What to watch for

The US Food and Drug Administration is on track to approve Johnson & Johnson’s vaccine sometime today, or possibly over the weekend, after releasing research on Wednesday (Feb. 24) that concluded the shot was effective.

It all happened in a little over a year. Here’s how it came together:

Jan. 2020: Johnson & Johnson receives the genetic sequence of SARS-CoV-2, the virus that causes Covid-19.

July 2020: The company develops its single-shot Covid-19 vaccine candidate and begins early stage clinical trials.

Sept. 2020: The Phase 3 trial begins, with the goal of including up to 60,000 participants.

Jan. 29, 2021: The company releases preliminary data from the clinical trial.

Feb. 4, 2021: Johnson & Johnson submits its vaccine to the US Food and Drug Administration (FDA) for emergency use authorization.

Feb. 24, 2021: The FDA releases a 62-page review of the vaccine, which finds it safe and effective.

Charting US Treasury yields

Investors in the $20 trillion US Treasury market tend to demand higher yields when they’re worried about inflation. That’s why it’s notable that interest rates on 10- and 30-year Treasury securities are back to or higher than they were before the pandemic.

A line chart showing 2-, 5-, 10-, and 30-year US Treasury yields from March 2020 to February 2021. While yields for 2- and 5-year Treasury securities remain low, interest rates on 10- and 30-year Treasury securities are back to or higher than they were before the pandemic.

The question is whether the US economy, already rebounding naturally as vaccines go into arms and people start spending their pent-up savings, overheats from heavy government support—and whether the Federal Reserve can contain inflation if it does.

Behind Hong Kong’s crowdsourced protest manual

“It’s like running a business. You need to find good people, you need to keep good people, you need to make them better people. You often need to find the resources, maybe it’s funding, cars, supplies. And they are fairly boring elements, I suppose. But they are precisely the thing that you need.”

The HK19 Manual,” a crowdsourced archive of Hong Kong protesters’ know-how created to help future demonstrators, has already been partially translated into Burmese and widely shared among protesters in Myanmar, who are demonstrating against the Feb. 1 military coup. Mary Hui spoke with a key contributor about putting together the protest manual and the broader lessons about social movements.
