Zika is still spreading. Why don’t we have a vaccine yet?

“Despite the decline in attention, Zika is still spreading in many countries. In the first half of 2023, health officials recorded about 27,000 Zika infections in the Americas, with Brazil the most affected country with more than 2,700 cases. Thousands of babies are still being born with preventable disabilities.
“With a safe and effective Zika vaccine, we could eliminate the possibility of congenital Zika syndrome, and I think that would have a huge impact,” said Anna Durbin, a professor of international health and global disease epidemiology and control at Johns Hopkins University. “Even if there are few cases of congenital Zika syndrome, just the emotional, financial effect of that is huge.”

Scientists and global health experts warn that Zika, alongside other mosquito-borne infectious diseases, could make a broader resurgence. The first step to defeating pandemics is, of course, prevention, and a Zika vaccine is vital to that goal.

But major hurdles stand in the way. Private pharmaceutical companies aren’t willing to invest in vaccine development because so few people are getting infected now — and those who are getting infected largely live in relatively poor countries. Researchers say governments aren’t investing sufficient public funds in vaccine development. And it is almost impossible to run a traditional clinical trial for the few vaccines hastily developed during the 2015 outbreak.”

Should We Blame Fauci for the COVID Pandemic?

“Prior to COVID-19, Fauci had long supported funding pandemic research that other scientists found risky, if not downright dangerous.
In 2005, as NIAID director, he praised researchers who’d used a grant from his agency to resurrect the virus that had caused the Spanish flu pandemic. Better understanding that virus would help prevent future diseases, he argued. “The certain benefits to be obtained by a robust and responsible research agenda aimed at developing the means to detect, prevent and treat [future pandemics] far outweigh any theoretical risks,” he said in an October 2005 statement co-authored with then–CDC Director Julie Gerberding.

This wasn’t a universal opinion at the NIAID. The agency’s chief scientist described this approach to pandemic prevention as “looking for a gas leak with a lighted match.”

Fauci would continue to praise and fund this kind of research. In 2011, researchers at the University of Wisconsin and at Erasmus University Medical Center in the Netherlands managed to manipulate the virus H5N1 (which had been responsible for a 2004 bird flu epidemic in Asia) to transmit between mammals, a “gain of function” for a virus that had heretofore only been able to pass from infected birds to humans. One of the researchers involved in the work would say the enhanced pathogen they’d created was “very, very bad news” and “probably one of the most dangerous viruses you can make.” Fauci was more sanguine, telling The New York Times that “there is always a risk. But I believe the benefits are greater than the risks.””

“In 2014, there was a series of embarrassing safety lapses at U.S. government labs, highlighting this risk.

Dozens of CDC employees were potentially exposed to live anthrax samples shipped by mistake to labs not equipped to handle them. At another CDC lab, a less dangerous version of bird flu was accidentally contaminated with deadly H5N1. Vials of smallpox capable of infecting people were stashed in a cabinet at an NIH lab, where they’d apparently been sitting for decades. None of these incidents were direct results of gain-of-function research. But they heightened the concern that researchers working to enhance deadly pathogens might do so in unsafe settings.”

“In 2021, Fauci said the NIH “has not ever and does not now fund gain-of-function research in the Wuhan Institute of Virology.” That wasn’t true. What EcoHealth was doing in Wuhan clearly met the widely understood definition of gain-of-function research.

In his June 2024 testimony, Fauci dodged accusations that he lied by saying that while EcoHealth’s work might have met a generic definition of gain-of-function research, it didn’t meet the precise definition established in the P3CO framework.

Fauci said that every time he mentioned gain-of-function research, “the definition that I use is not my personal definition; it is a codified, regulatory and operative definition.” That definition, he said, “had nothing to do with me.”

On the contrary, regulatory definitions had quite a bit to do with Fauci. They were designed with the expectation that he and his fellow public health bureaucrats would use discretion and good judgment when making decisions. The relevant regulatory language included lots of “likelys and highlys and reasonably anticipated,” says Gerald Epstein, a former director at the White House Office of Science and Technology Policy who wrote the P3CO policy. “These words are inherently subjective. You can’t not be. You’ve got to be making judgment calls on something that does not yet exist.” Those subjective definitions gave Fauci and his NIAID underlings considerable room to decide what research required additional review.”

“We probably won’t ever definitively discover the origins of COVID-19.”

“Chinese officials obstructed any investigation into the Wuhan Institute of Virology. In September 2019, the Associated Press reported, the institute took its database of viruses offline. It also hasn’t made public lab notebooks and other materials that might shed light on exactly what kinds of work it was doing in the lead-up to the pandemic. In late 2019, the Chinese government also exterminated animals and disinfected the Wuhan wet market. If COVID did leap from animal to human in the Wuhan market, as many natural origin proponents argue, that evidence is gone.

What we’re left with is studying the structure of the SARS-CoV-2 virus itself and whatever information can be gleaned from the U.S.-funded research that went on at Wuhan leading up to the pandemic.

On both fronts, Fauci, his underlings at the NIAID, and NIAID-funded scientists involved with work at Wuhan have worked to conceal information and discredit notions that COVID might have leaked from a lab.

In late January 2020, Fauci’s aides flagged the NIAID’s support of EcoHealth’s Wuhan research in emails to their boss. A few weeks later, Fauci and Daszak would go on Newt Gingrich’s podcast to dismiss the idea that COVID-19 came from the Wuhan lab, calling such arguments “conspiracy theories.”

Both men also worked to shape the discourse behind the scenes away from any focus on a lab leak. Daszak organized a group letter of scientists in The Lancet, the U.K.’s top medical journal, declaring that they “stand together to strongly condemn conspiracy theories suggesting that COVID-19 does not have a natural origin.” Daszak did not disclose his relationship to the Wuhan lab when organizing this letter; The Lancet’s editor would eventually concede that this was improper.

In testimony to the House coronavirus subcommittee in May 2024, Daszak would claim the “conspiracy theories” mentioned in the Lancet letter referred only to such wild early pandemic notions that COVID had pieces of HIV or snake DNA inserted into it. He said a word limit prevented him from being more precise.

Fauci, meanwhile, would help corral virologists into publishing the widely cited “proximal origin” paper in early 2020. In the paper, the authors flatly declared that “we do not believe any type of laboratory-leak scenario is plausible.”

Yet troves of private messages and emails released by the House subcommittee’s investigation show that the authors privately expressed far more openness to a lab leak theory.

One of the paper’s authors, Scripps Research evolutionary biologist Kristian Andersen, privately rated a lab leak as “highly likely.” But Andersen had a pending $8.9 million grant application with the NIAID as the paper was drafted. That grant was later approved. In an email, one of the paper’s authors, Edward Holmes, references “pressure from on high” during the drafting process.

The authors of the proximal origin paper say they merely had their minds changed while drafting the paper. They were just following the scientific method.”

“Fauci’s best defense is that he ran a sprawling agency that doled out billions of dollars in grants. Even the most detail-obsessed administrator couldn’t possibly keep track of every single program and project. And U.S. officials had limited control over what happened in the distant, opaque Wuhan lab.

But even if that’s true, it’s an admission of administrative negligence, since the oversight protocols weren’t followed. It also implies a dramatic failure of the risky research that Fauci championed for pandemic prevention. As Ridley says, the pandemic “occurred with the very viruses that there was the most attention paid to, in the very area where there was the most research going on, where there was the biggest program looking for potential pandemic pathogens, and yet they failed to see this one coming.” At a minimum, gain-of-function research didn’t protect the public from the pandemic.

Meanwhile, the more direct case against Fauci is strong: Not only was he an ardent supporter of research widely believed to be risky, but he manipulated bureaucratic protocols in order to avoid scrutiny of that research, then responded evasively when called to account for his actions. At least one of the programs born out of Fauci’s risky research crusade was pursuing exactly the type of viral enhancements that were present in COVID-19, and that research was conducted at the Wuhan virology lab in the very same city where the virus originated. Lab leak proponents cite the virus’s transmissibility as evidence for a Wuhan leak: After all, EcoHealth was trying to create pathogens primed to spread rapidly in humans.

The evidence is not fully conclusive. But it seems reasonably likely that Fauci pushed for what his peers repeatedly said was dangerous research, that some of that dangerous research produced a deadly viral pathogen that escaped the lab, and that Fauci helped cover up evidence and arguments for its origins.”

Trump’s campaign against public health is back on

“People are already losing trust in vaccines: Only 40 percent of Americans believe it is extremely important for parents to get their children vaccinated, down from 64 percent in 2001. It is perhaps the most worrying trend in public health right now.
We have the tools to stop many infectious diseases — if we take advantage of them. Trump’s words are making it less likely that people will.”

“Meanwhile, measles cases in the US matched their 2023 total over just the first few months of 2024. A local outbreak in Oregon has seen nearly two dozen cases since June; at least two people have been hospitalized.

A disease that was once effectively eradicated in the US — and which school mandates helped to stamp out — is mounting a comeback.

Donald Trump could choose to wield his tremendous influence to try to restore people’s faith in vital public health measures. He did it, if half-heartedly, during the pandemic and it had the desired effect. Instead, he’s stoking doubts about the value of vaccines, and courting the dangers vaccine hesitancy brings.”

Why are so few people getting the latest Covid-19 vaccine?

“Experts say the public’s disinterest in the latest Covid shots is likely a combination of poor messaging from authorities, a diminishing fear about a virus that three years ago was wholly unknown, and the political polarization of the pandemic itself. But whatever the reasons, that vaccine ambivalence still poses a health threat.
Elderly people and very young infants continue to have a higher chance than the rest of the population that they will be hospitalized with Covid-19. Vaccination rates have fallen off for the former group, who are also most likely to die from an infection, and they were never strong to begin with for the latter”

“The known unknowns for the future, which could spur another round of investment and interest in updated Covid-19 vaccines, are biological. The virus has been evolving and will continue to evolve and could, in theory, reach a point where the current vaccines are ineffectual.

The other question mark is inside of us. The reason many people still enjoy protection from serious illness is because our body’s T-cells are familiar with the virus and can activate when they detect it. They may not be able to stop an infection entirely (that is the role of antibodies, which are quicker to fade) but they can stamp out the virus before a person becomes too sick.

What we don’t know today is how long our T cells’ memory will last, and how durable that immunity really is. The only way to find out is for more time to pass.”

The US has never recorded this many positive flu tests in one week

“Some portion of this steep rise in cases is related to the fact that more people are being tested for the flu than in previous years. Over the month of November, about twice as many flu tests were done at clinical labs nationwide as during the same period last year (about 540,000 versus 265,000). More testing means more cases will get picked up.
However, there are corroborating warning signs that this is truly a bad season. Flu hospitalizations have been off the charts and are rising quickly. In a press conference Monday, CDC director Rochelle Walensky said there have already been 78,000 flu hospitalizations this season, or nearly 17 out of every 100,000 Americans. That’s “the highest we’ve seen at this time of year in a decade,” she said. In keeping with past trends, the highest hospitalization rates are among adults 65 and older.

What’s making these high hospitalization rates particularly concerning is their overlap with surges in other viruses causing many people to get sick enough to require admission. One of those is RSV, which has been packing pediatric hospitals for more than six weeks. And while Walensky noted there were signals RSV transmission was slowing in parts of the country, Covid-19 hospitalizations recently began to tick upward.”

A worldwide monkeypox outbreak

“The worldwide monkeypox outbreak began in early May 2022. Since then, more than 15,000 cases of monkeypox have been identified across more than 60 countries. Disease caused by the monkeypox virus typically involves a few days of fever and lymph node swelling followed by a rash, which can leave scars. Most cases in the current outbreak have resolved without hospitalization or the need for medication. As of July 20, there have been five deaths, all of them in Africa.
Monkeypox is related to the smallpox virus, and immunity to smallpox is protective against monkeypox. But as of 1980, smallpox has been eradicated in humans, and vaccinations against smallpox have grown rare — and human cases of monkeypox have been on the rise.

With monkeypox, the world faces a very different situation than in the early days of Covid-19. Monkeypox, unlike SARS-CoV-2, is a known quantity. We have more tools to prevent and treat it — far more than we did for Covid-19 at the outset of the pandemic — and both public health and the general public have had a lot of practice taking measures to prevent infections from spreading.”
