and COVID-19 using messenger RNA generated antibodies in a study, butregulators want to see data on whether the new vaccine protects people from getting sick.Researchers from vaccine-maker Moderna reported in a study published Wednesday that the new combo shot generated a stronger immune response against COVID-19 and most strains of flu than existing standalone shots in people 50 and older. Side effects were injection site pain, fatigue and headaches. Moderna previously reported a summary of the results from the company-sponsored trial in 8,000 people.

The mRNA technology is used in approvedshots, but has not yet been approved for a flu shot. Moderna believes mRNA could speed up production of flu shots compared with traditional processes that use chicken eggs or giant vats of cells. A combo shot also might improve vaccination rates, the researchers wrote in the study published in the Journal of the American Medical Association.

Dr. Greg Poland, who studies vaccine response at Mayo Clinic and was not involved in the new study, said he’s not convinced that a combo shot would be popular. And while flu comes in seasonal waves, COVID-19 has been spreading throughout the year, Poland said, posing challenges for how to time the shots to keep protection strong.

He’d also like to see data on how well the new shot protected people from infection and hospitalization.“If you’re looking for a good investment, go straight to vintage. Things that have already stood the test of time often have another 50 years left in them! Side tables, desks, even cabinets are great pieces to look for,” he says.

Mendelson mentions a pair of vintage French plaster shell sconces in his Sagaponack, New York, home. He bought them 15 years ago “and they still feel fresh and relevant today.”“I think a desire for one-of-a-kind and bespoke is at least starting a conversation about handmade,” he says. “Quality vs quantity. Living with intention.”

Many retailers are getting seats on the slow train. West Elm, for instance, was early among home retailers in joining Fair Trade USA, which ensures that suppliers maintain good workplaces and wages, and support their communities.The global reforestation project One Tree Planted gets part of every purchase from furniture brand Joybird. Herman Miller’s rePurpose program gets used furniture to nonprofit organizations. And Ikea has initiatives like moving to bio-based glue, and instituting a buy-back/re-sell program that saw 230,000 items given a new life in 2022.
