COVID delta variant fears spur booster shot plans around the world. The latest update

The WHO calls for a pause in the world’s booster plans, while San Francisco gives Johnson & Johnson recipients the green light for an mRNA dose. Here’s what’s going on with boosters.

Calling the eradication of the COVID-19 virus “unlikely,” a UK scientific advisory group says (PDF) there is a “realistic possibility” that a variant will emerge that is resistant to the current battery of vaccines. Governments, public health organizations and vaccine makers are all tracking developments in coronavirus variants like delta and lambda, hoping to answer the question if booster shotstargeting new variants will be needed soon.

“Things are going to get worse,” Dr. Anthony Fauci, the chief medical advisor to the president, said Sunday on ABC’s This Week.

Currently in the US, “breakthrough” coronavirus cases caused by the dominant delta variant amount to less than 1% of people who are fully vaccinated. Both Moderna and Pfizer vaccines are proven to be over 90% effective against hospitalizations and death. The surge in new COVID-19 cases are primarily affecting unvaccinated people and causing community spread, and in turn, the return of mask mandates and guidance in hard-hit areas, even for people who have full vaccine protection. The debate over mask use and vaccine boosters underscores how scientists and other health experts continue to grapple with the uncertainties of COVID-19.

The Centers for Disease Control and Prevention’s recent study shows that vaccinated people can both contract the highly contagious delta variant and spread it. According to a widely reported internal CDC memo, the delta variant spreads as easily as chicken pox, which is considered more contagious than the flu and less contagious than measles.

To prepare for the possibility of a booster shot, the CDC said it’s weighing a third vaccine dose for people with compromised immune systems. Over the weekend, Israel began administering third doses of the vaccine to those 60 and older, and the UK plans to do the same. However, this is resulting in a backlash among countries that are struggling to deliver first and second shots to residents.

On Wednesday, World Health Organization Director-General Tedros Adhanom Ghebreyesus called for a “moratorium” on booster shots in high-income countries, citing the global disparity in vaccine distribution. Of the 4 billion doses administered globally, 80% have gone to high- and upper-middle income countries that make up less than half of the world’s population, he said.

“We cannot accept countries that have already used most of the global supply of vaccines using even more of it, while the world’s most vulnerable people remain unprotected,” Tedros said.

What does all of this mean in the US? Here’s what we know about COVID booster shots now.

Booster shot vs. new COVID vaccine: There’s a difference

Along with Moderna, Pfizer’s current two-dose vaccine provides powerful and effective protection against all known variants of COVID-19, including the delta variant, according to ongoing studies and self-reported statistics. But Pfizer also announced in July that a third dose of its vaccine is currently under development. The company said its own research showed a booster shot of its current vaccine increased antibody levels five to 10 times higher over its two-dose shots, noting that its results have not been published or peer-reviewed.

Pfizer said it believes the level of protection the first two doses of its vaccine provide can gradually decrease over time, and a third booster dose may be needed “within six to 12 months” after a person is fully vaccinated with the first two doses. Pfizer said a booster shot could enhance protection against the delta variant, which has been known to infect fully vaccinated people. Clinical trials on the booster are set to begin, as Pfizer seeks approval from government regulators for a third dose.

However, while a booster shot would complement the two doses of its existing vaccine, Pfizer is also separately working on a new vaccine formulation targeting the delta variant.

What do the CDC, FDA and WHO think about a booster shot?

The CDC and FDA initially exercised caution over a booster shot.

“People who are fully vaccinated are protected from severe disease and death, including from the variants currently circulating in the country such as delta,” the CDC and FDA said in a July 8 joint statement, without naming Pfizer. The government agencies emphasized the need for all eligible people to receive full doses of one of the approved vaccines, all of which are free.

The CDC and FDA said the question of a booster requires extensive scientific data and doesn’t depend on the input from pharmaceutical companies alone. “Virtually all COVID-19 hospitalizations and deaths are among those who are unvaccinated,” the statement mentioned, adding that the agencies will approve booster doses “if and when the science demonstrates that they are needed.”

New research has demonstrated a need. There is a growing consensus among Biden administration health officials that older individuals and those with compromised immune systems may, in fact, need a third shot. At a White House press briefing Thursday, Fauci said that it is “extremely important for us to move” to get immunocompromised people a booster, citing observational data that they generally aren’t “adequately protected” with the standard vaccine dose.

“We are now working on that, and we’ll make that be implemented as quickly as possible,” Fauci said. About 2.7% of the US adult population is immunosuppressed, CNBC reported, but immunocompromised people make up about 44% of people hospitalized with COVID complications.

Earlier in the week, at a WHO press briefing Wednesday, Tedros said that while he understands “the concern of all governments to protect their people from the delta variant,” booster shots shouldn’t be prioritized until the world’s most vulnerable people and health care workers are vaccinated.

“We call on vaccine producers to prioritize Covax,” Tedros said, referring to the world’s COVID-19 vaccine distribution program.

Is Moderna also planning to develop a booster shot?

While scientists and public health officials continue to study if those who are fully vaccinated will need a booster shot, Moderna said — along with Pfizer — it is exploring a third vaccine dose to complement the initial two vaccine shots.

I got Johnson & Johnson — Do I need a booster?

No, fully vaccinated Americans don’t need a booster yet, including those who got the single dose of Johnson & Johnson’s COVID vaccine, according to the country’s health officials. But residents in San Francisco who received Johnson & Johnson’s one-dose COVID vaccine were given the green light Tuesday to get a dose of an mRNA vaccine, though it still isn’t recommended by the city’s health department.

Dr. Grant Colfax, San Francisco’s health director, said that there isn’t conclusive evidence that getting a dose of Pfizer or Moderna benefits those who got the J&J shot, but there’s also not evidence to show it’s harmful, the San Francisco Chronicle reported.

“If people received the Johnson & Johnson and are requesting a second shot, we will accommodate them, but our policy has not changed,” Colfax said.

San Francisco’s decision to legitimize Johnson & Johnson vaccine recipients getting an mRNA vaccine comes in light of a small study that suggests the vaccine isn’t nearly as effective against the delta variant as the other vaccines. (Another study suggests that Johnson & Johnson remains effective, and the drug-maker continues to claim the vaccine is effective.)

Would the booster shot be free?

The current one-dose vaccine shot from Johnson & Johnson and two-dose versions from Moderna and Pfizer are free to anyone who wants to get vaccinated. According to the Biden administration, COVID-19 booster shots will also be free, if and when they’re approved.

Is it a good idea to mix and match COVID vaccines?

The CDC doesn’t recommend mixing and matching vaccines from the different makers, saying it hasn’t evaluated the effectiveness of mixing vaccine doses and that the “vaccines are not interchangeable.”

However, other global health agencies and countries are testing administered vaccines from two different manufacturers. In the UK, for example, a recent study found that those who received a first dose of the AstraZeneca vaccine and a second of Pfizer had a higher immune response than those who received two doses of the AstraZeneca vaccine.

In early June, the National Institutes of Health started a trial that tests mixing COVID-19 vaccines, and will determine if those who got Pfizer or J&J initially can safely receive a Moderna booster. The initial results of the study are expected in late summer 2021, the NIH said in a news release.

While we wait to see how the situation develops, here’s what we know about the delta variant, more about COVID-19 boosters and if you need to continue to wear a mask.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration

European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.

BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.

The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.

Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.

However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.

Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.

European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge

Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.

Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.

Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.

The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.

Mortgage rates track the 10-year Treasury yield

Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.

In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.

Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.

If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.

But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.

There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.

That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.

Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.

CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.

“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.

AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.

GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.

Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.

In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.

And that’s leaving aside the deep animosity between the parties.

The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.

For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network

Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.

Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.

Kyiv has leveled accusations against SpaceX

Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.

Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.

Here’s an overview of Starshield and its distinctions from Starlink.

What is Starshield and how does it function?

Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.

SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.

In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.

SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.

On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.

How does Starshield contrast with Starlink?

While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.

Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.

Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.

SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
