An experimental vaccine against the coronavirus showed encouraging results in very early testing, triggering hoped-for immune responses in eight healthy, middle-aged volunteers, its maker announced Monday.

Study volunteers given either a low or medium dose of the vaccine by Cambridge, Massachusetts-based Moderna Inc. had antibodies similar to those seen in people who have recovered from COVID-19.

In the next phase of the study, led by the U.S. National Institutes of Health, researchers will try to determine which dose is best for a definitive experiment that they aim to start in July.

In all, 45 people have received one or two shots of the vaccine, which was being tested at three different doses. The kind of detailed antibody results needed to assess responses is only available on eight volunteers so far.

The vaccine seems safe, the company said, but much more extensive testing is needed to see if it remains so. A high dose version is being dropped after spurring some short-term side effects.

The results have not been published and are only from the first of three stages of testing that vaccines and drugs normally undergo. U.S. government officials have launched a project called “Operation Warp Speed” to develop a vaccine and hopefully have 300 million doses by January.

Worldwide, about a dozen vaccine candidates are in the first stages of testing or nearing it. Health officials have said that if all goes well, studies of a potential vaccine might wrap up by very late this year or early next year.

More than 4.7 million infections and 315,000 deaths from the coronavirus have been confirmed worldwide since it emerged in China late last year. There are no specific approved treatments, although several are being used on an emergency basis after showing some promise in preliminary testing.

Michigan Judge Sentences Walmart Shoplifters to Wash Parking Lot Cars
A Michigan judge is putting sponges in the hands of shoplifters and ordering them to wash cars in a Walmart parking lot when spring weather arrives. Genesee County Judge Jeffrey Clothier hopes the unusual form of community service discourages people from stealing from Walmart. The judge also wants to reward shoppers with free car washes. Clothier says he began ordering “Walmart wash” sentences this week for shoplifting at the store in Grand Blanc Township. He believes 75 to 100 people eventually will be ordered to wash cars this spring. Clothier says he will be washing cars alongside them when the time comes.
State Department Halts Plan to buy $400M of Armored Tesla Vehicles
The State Department had been in talks with Elon Musk’s Tesla company to buy armored electric vehicles, but the plans have been put on hold by the Trump administration after reports emerged about a potential $400 million purchase. A State Department spokesperson said the electric car company owned by Musk was the only one that expressed interest back in May 2024. The deal with Tesla was only in its planning phases but it was forecast to be the largest contract of the year. It shows how some of his wealth has come and was still expected to come from taxpayers.
Goodyear Blimp at 100: ‘Floating Piece of Americana’ Still Thriving
At 100 years old, the Goodyear Blimp is an ageless star in the sky. The 246-foot-long airship will be in the background of the Daytona 500 — flying roughly 1,500 feet above Daytona International Speedway, actually — to celebrate its greatest anniversary tour. Even though remote camera technologies are improving regularly and changing the landscape of aerial footage, the blimp continues to carve out a niche. At Daytona, with the usual 40-car field racing around a 2½-mile superspeedway, views from the blimp aptly provide the scope of the event.
Is U.S. Restaurants’ Breakfast Boom Contributing to High Egg Prices?
It’s a chicken-and-egg problem: Restaurants are struggling with record-high U.S. egg prices, but their omelets, scrambles and huevos rancheros may be part of the problem. Breakfast is booming at U.S. eateries. First Watch, a restaurant chain that serves breakfast, brunch and lunch, nearly quadrupled its locations over the past decade to 570. Fast-food chains like Starbucks and Wendy's added more egg-filled breakfast items. In normal times, egg producers could meet the demand. But a bird flu outbreak that has forced them to slaughter their flocks is making supplies scarcer and pushing up prices. Some restaurants like Waffle House have added a surcharge to offset their costs.
