(Bloomberg) -- What’s buzzing on social media this morning:

Norway warned Covid-19 vaccines may be too risky for the very old and terminally ill. The country reported 29 people over the age of 75 who died after taking their first Covid-19 vaccination shot.

• Until Friday, Pfizer/BioNTech was the only vaccine available in Norway, and Pfizer said the companies are working with the Norwegian regulator to investigate the deaths.
• The reported deaths were “elderly people with serious basic disorders.” Norway’s recommendation does not mean younger, healthier people should avoid being vaccinated.

In New Jersey, smokers are now eligible for Covid-19 shots under the state’s vaccine expansion plan. No proof is needed. Smoking and obesity are among the conditions listed under “individuals at high risk,” the plan shows.

Germany’s governing CDU party elected Armin Laschet as next leader, opting for the candidate who most resembles departing Chancellor Angela Merkel in policy and style.

President-elect Joe Biden picked Wendy Sherman, a former undersecretary of state for political affairs under President Barack Obama, as deputy secretary of state. A regular critic of President Donald Trump on Twitter, Sherman was the lead U.S. negotiator in talks that led to the 2015 agreement between Iran and world powers on the Islamic republic’s nuclear program.

The Maryland Department of Transportation is suspending its MARC commuter train service ahead of President-elect Joe Biden’s inauguration amid threats of unrest.

The Justice Department executed Dustin Higgs, 48, early Saturday, the 13th and final federal inmate scheduled to die during President Donald Trump’s term. The opinion of Justice Sonia Sotomayor, one of the three justices who dissented, trended on Twitter, including in a post by Helen Prejean, the Roman Catholic nun portrayed by Susan Sarandon in the 1995 film “Dead Man Walking” based on Prejean’s book of the same name.
