South Africa vaccines, ETF shorts, marijuana shortages

Good morning, Quartz readers!

Here’s what you need to know

South Africa halted its AstraZeneca rollout. Early data from a small study—not yet peer reviewed—suggest the vaccine could offer “minimal protection” against mild Covid-19 caused by a local coronavirus variant.

But UK officials remain confident. The AstraZeneca jab could still havegood efficacy against severe disease, hospitalization, and death,” says vaccine minister Nadhim Zahawi.

Oil prices recovered to pre-pandemic levels. Despite demand for oil still lower than usual, this could be another good sign for the broader global economy.

Hyundai’s EV deal with Apple is off. The collapse in negotiations wiped $8.5 billion from Hyundai and its affiliate Kia’s market values.

Tom Brady won his seventh Super Bowl. The quarterback helped the Tampa Bay Buccaneers beat the Kansas City Chiefs 31-9 in a low-key version of the biggest sporting event in the US.

What to watch for

In light of more infectious coronavirus variants, the US Centers for Disease Control and Prevention is now researching whether wearing two masks may be more beneficial than one. US president Joe Biden, top infectious disease expert Anthony Fauci, and White House press secretary Jen Psaki have already been seen doubling up.

Katherine Foley looks at what we know so far about double masking. Depending on the kinds of masks you’re layering, there is potential for added filtration, and more filtration means less likelihood of encountering a pathogen-containing particle.

Charting the rise of ETFs

These days, all eyes are on short-selling. But while troubled companies like GameStop and AMC Theaters may seem like obvious targets for shorting, Karen Ho reports that exchange-traded funds (ETFs) are proving even more enticing.

ETFs, which track a number of underlying investments in a particular industry or market segment, have grown into a $5 trillion industry during the pandemic, fueled by new investments, low interest rates, and investor optimism. Shorting index ETFs is one way for traders to diversify and reduce risk, but experts say the “extreme level of nimbleness and discipline” required makes it a tactic beginners would do well to avoid.

Case of the Mondays?

At work, there’s a fine line between being a team player and a pain in your boss’s neck; those who walk it gracefully are “productive skeptics.” While plenty of us are born with one eyebrow raised, steering that energy productively is a skill you can learn, starting with these tips:

  • Don’t be a martyr. Work can’t be all courageous acts.
  • Choose your battles. And pick the right time to engage in them.
  • Follow through. That includes asking for what you need.
  • Smooth ruffled feathers. Don’t start fights you can’t fix.
