Hereâs what you need to know Joe Biden opened his Summit for Democracy. The US president is virtually meeting with 80 other leaders to discuss how [freedoms have declined worldwide](. Meanwhile, Chinaâwhich was not invited to the summitâis [trying to redefine the narrative](. China sent a warning to countries boycotting the 2022 Olympics. Governments not sending officials to Beijing in protest of the countryâs human rights abuses “[will pay the price for their mistaken acts](,â a spokesperson said. Covid restrictions ramp up in the UK as omicron spreads.

US inflation data will likely show consumer price hikes. The government sought to downplay the Consumer Price Index report ahead of its release today, [saying it was “backward looking.”]( A truck crash in Mexico killed 54. More than 150 people, mostly migrant workers, were crammed [into the vehicle when it rolled](, in one of the deadliest such crashes in Mexican history. Pfizer/BioNTechâs booster was approved for 16- and 17-year-olds in the US. The US Food and Drug Administrationâs authorization made the shot available to [2.6 million teens](.

In practice, the name change doesnât mean very much. But the switch from Square to Block reflects CEO Jack Dorseyâs ambition to [build a tech conglomerate]( in the image of Amazon, Alphabet, and Meta. Each of these parent companies has a huge, steady stream of revenue from their core businesses that finance expensive, experimental side projects to extend their dominance. [A graphic showing tech conglomerates Alphabet, Meta, and Block being made up of 9, 91, and 4 companies respectively.] Dorsey never had a chance to do that as the CEO of Twitter, [a role he gave up on Nov. 29](. Square makes three times Twitter’s revenue, and Block gives Dorsey a chance to redirect some of it towards cryptocurrencies, his personal obsession. (Whatâs next for Twitter? Members can find out in our latest issue of [The Company](.) Should we trust Pfizer about omicron? Early evidence indicates three doses of Pfizerâs vaccine show significantly more protection against the omicron covid-19 variant, compared to two doses. While the drugmakerâs internal test results could well be accurate, independent reviews without the same biases might find less encouraging outcomes from those of the company. On one hand: ð¤In this rapidly changing environment, every piece of information should be shared as soon as possible. On the other: ð Constantly published information, particularly if itâs contradictory, can erode trust, and even provide ammunition to those willing to discredit public health authorities. What should we do? ð¤·ââï¸ [Wait for more context](. For instance, an independent review found that Merckâs antiviral pill for covid-19 was far less effective than the company had announced once its efficacy was reviewed independently. Remember, no vaccine is a magic bullet, but vaccines plus [good masks]( and social distancing is about the safest you can get. Letâs do some math The US is the only wealthy country where workers are not universally guaranteed an income during critical periods in life, like stepping back from work, caring for a new baby or aging family member, or dealing with personal illness. But the Democratsâ Build Back Better spending bill includes a proposal for a paid family leave program that would change that.
