Good morning, Quartz readers!
Here’s what you need to know
Johnson & Johnson submitted its Covid-19 jab for US approval. The single-shot vaccine would become the third on the market if it gets a regulatory nod. See more below.
Meanwhile, the EU has fallen behind on vaccines. The 27-country bloc’s experiment in collective bargaining is likely to blame for its slow and controversial rollout.
The US House punished a Republican congresswoman. Marjorie Taylor Greene had promoted dangerous conspiracy theories, and has been kicked out of two committees.
“Focus on New York and Singapore, not Frankfurt and Paris.” Barclays’ CEO Jes Staley says the UK’s financial services industry can thrive in a post-Brexit world.
The US is taking steps towards breaking China’s rare earths monopoly. They have a crucial role in the manufacture of high-tech products.
The Fortune 500 is losing one of only four Black CEOs. Merck boss Kenneth Frazier retires at the end of June.
GameStop Redditors are fighting amongst themselves. Moderators of the WallStreetBets message board are battling over apparent interest from Hollywood.
What to watch for

TikTok’s Chinese rival surged 200% in its Hong Kong debut. Short video app Kuaishou opened at HK$338 ($43.6), nearly triple its IPO price of HK$115. It’s the biggest tech IPO since Uber in 2019.
The surge in investor interest could be, in part, a result of liquidity in the market, but the oversubscription is also a confidence vote for Kuaishou’s focus on grassroots users from small towns. A rival to TikTok, Kuaishou’s videos often feature users from rural areas, who film themselves feeding chickens or pulling off pranks on friends.
Although Kuaishou still lags behind TikTok (or Douyin, as it’s known in China), its strategy of advocating the value in ordinary people’s lives could please a China that has become increasingly uncomfortable with the rich and powerful.
Charting Robinhood’s dealings with large trading firms
One of the things that has always complicated Robinhood’s finance-for-the-little-guy pitch is that the company works hand in glove with the big guys. The main way the brokerage makes money is that it sells its retail transactions to large trading companies that execute the trades.
Robinhood Securities received $71 million in order flow payments for stocks and options in December, according to a filing, more than half of which came from hedge fund billionaire Ken Griffin’s Citadel Securities.

Robinhood’s story of financial democratization came under fire last week when it blocked traders from buying GameStop and other stocks. John Detrixhe unpacks what’s really going on.
What’s next for Amazon
Succession plans are a bit like airplane landings: They only make news when something goes wrong. While it’s too soon to tell if Amazon’s CEO transition from Jeff Bezos to Andy Jassy will hit the tarmac smoothly, there is no shortage of ways it could get bungled.
Let’s hope it fares better than these succession disasters:
🐭 Disney: Michael Eisner ➡️ Michael Ovitz
🏈 New York Jets: Bill Belichick ➡️ Bill Parcells ➡️ Bill Belichick
📺 The Tonight Show: Jay Leno ➡️ Conan O’Brien
👑 England’s throne: Edward VIII ➡️ George VI
Even assuming all goes well, Bezos is leaving behind some unfinished business.

You asked about the Janssen vaccine’s lower efficacy
Since the Janssen vaccine is not as effective as Pfizer or Moderna’s, does that mean it’s not as good at helping the world beat Covid-19?
You’re right—Janssen says its Covid-19 vaccine can prevent 66% of symptomatic cases, while vaccines from Pfizer-BioNTech and Moderna showed they could stop over 90% of symptomatic cases. But Janssen’s vaccine shines by another metric: reducing the severity of the disease, potentially freeing up hospital beds.
One of the most dangerous effects of Covid-19 is that it sends about 2% of patients to intensive care units in hospitals. The more Covid-19 patients lying in hospital beds, the more likely overwhelmed hospitals will be unable to treat future Covid-19 cases and unrelated medical emergencies. Across the US, roughly 77% of ICU beds are occupied at the time of writing, according to Johns Hopkins University’s Covid-19 tracker.
According to company data released on Jan. 29, Janssen’s vaccine prevents 85% of severe Covid-19 cases, which is great news from a public health standpoint. “To keep people out of the hospital and prevent death—this is value added,” said Anthony Fauci, the director of the US National Institute on Allergy and Infectious diseases on NBC Nightly News.
