The rush is on for immunity tests, but how available and useful will they be?


The ‘Wild West’ for Antibody Tests

As debate intensifies about how and when the United States can resume some semblance of life as we knew it before the coronavirus — and several Southern states moved to lift stay-at-home orders, despite health officials’ warnings — there’s more chaos surrounding a tool that’s seen as essential to getting back to normal: immunity testing.

“It’s already a case of the continuing Wild, Wild West,” said David Relman, a professor of microbiology and immunology at Stanford who is on a White House advisory panel on testing. “The sequel is certainly live and in action.”


Dozens of companies have rolled out tests that promise to tell users whether they have been exposed to the virus and therefore may have some kind of immunity — with the emphasis on “may.” These serology tests, which look for antibodies in blood that have the ability to fight off the virus, range from simple sticks to complex lab procedures.

But just as there have been problems with ramping up coronavirus tests, there may be a shortage of antibody tests. In some cases, the screenings require the same mixing liquids that are in short supply for those earlier tests, potentially sparking another round of fierce competition among states, cities and counties — and even the federal government — all vying for the same limited resources as more places begin immunity testing.

The reliability of the tests is also unknown, creating a marketplace where buyers should beware. And though most scientists hope the presence of antibodies does bring some immunity, no one yet knows how long it could last or whether it’s possible to get the virus more than once.

Still, public health officials are starting broader pilots of serology testing. In Los Angeles County, researchers released initial results finding that 4.1% of adults have antibodies to the virus in their blood, an indication of past exposure. That means hundreds of thousands of county residents may have been infected with the coronavirus by early April. But this and other studies show that we’re far away from achieving the “herd immunity” that, absent a vaccine, would be a key to returning to normal life.

A Tragic Father-Daughter Story

Chanell Jackson rubbed sanitizing gel on her hands and pulled a protective gown over her clothes as she had done so many times before. As a nurse, she did this ritual to help deliver wailing babies and wheel worried women into surgery. But this was different. This was her father.”

So begins reporter Angel Jennings’ story on Charles “Chuck” Jackson, who had guarded schools in L.A.’s toughest neighborhoods during the city’s most violent era, and his daughter Chanell, who chronicled his illness and death on social media to dispel the myth that black people were somehow immune to the coronavirus.


A Drop in the Barrel

The stunning collapse of oil prices Monday was the latest shock to an economy roiled by the coronavirus outbreak — and yet another jolt to an energy sector already grappling with a challenging transition from fossil fuels to cleaner power sources.

The price of West Texas crude fell to negative $37.63 per barrel as sellers scrambled to offload their May futures contracts before a Tuesday expiration date — even if they had to pay buyers to make the deal. The reason: With the pandemic bringing the economy to a standstill, there is so much unused oil sloshing around that American energy companies have run out of room to store it.

Contracts beyond May are still selling at relatively normal prices. But oil’s plunge into negative territory is just one piece of a larger story playing out across the energy sector, with long-term implications for the world’s ability to phase out the fossil fuels that are responsible for rising global temperatures.

‘The Biggest Slap in the Face’

Have you gotten your stimulus check? If you meet the income requirements and are a U.S. citizen, but you’re married to an immigrant who doesn’t have a Social Security number, the answer is probably no — and never.

More than 1 million U.S. citizens have been blocked from receiving stimulus checks simply because they filed a joint tax return with a spouse who does not have a Social Security number. The only exception is if one spouse is a member of the U.S. Armed Forces.

“It’s the biggest slap in the face that the government left us out,” said one woman in the Midwest.

On this day in 2016, Prince was found dead in his home near Minneapolis. It was a shocking end for one of pop’s greatest figures. He was one of the best-selling artists of all time, with a Rock and Roll Hall of Fame induction, seven Grammy Awards and an Academy Award for original song score for the 1984 film “Purple Rain.” “He was a misfit when there weren’t black misfits on a stage that big,” wrote The Times’ Marc Bernardin.

An investigation concluded Prince died from an overdose of fentanyl that had been mislabeled. He was 57.
