Companies won ’t share COVID-19 shots, stalling future vaccine research
The U.S. government has tens of millions of unused doses of messenger RNA (mRNA) COVID-19 vaccines, regularly trashing shots as they pass their expiration dates. It’s a dismal reflection on recent vaccine uptake, but it’s also a serious roadblock for scientists testing and developing vaccines that could protect against future variants of SARS-CoV-2—and the next pandemic. Developers need existing vaccines as a benchmark to compare with new candidates. But government contracts with the vaccinemakers, and the companies’ own policies, prohibit the use of the vaccines for research purposes.
“At this stage of the ...

Why It Took So Long to Finally Get an RSV Vaccine
Respiratory syncytial virus (RSV) can dangerously compromise breathing, especially for infants and the elderly. But there has been no vaccine to prevent it—until today. On May 3, the U.S. Food and Drug Administration (FDA) approved the first vaccine against RSV, from GlaxoSmithKline (GSK), to prevent respiratory disease in people ages 60 and older. The Centers for Disease Control’s vaccine committee will make formal recommendations in June about who should receive the vaccine, but GSK says it currently has enough doses to vaccinate eligible people beginning this fall.
In studies involving 25,000 people that GSK...

Science society lists Earth’s top ‘geoheritage’ sites
The International Union of Geological Sciences last week marked its 60th anniversary by announcing
a list of 100 “geoheritage” sites that have substantially influenced understanding of Earth’s deep history
. The global list, released in collaboration with UNESCO, is meant to foster conservation and tourism. The sites include familiar ones, such as the Grand Canyon’s “great unconformity,” a billion-year gap in the rock record erased by erosion. More exotic examples include limestones in Germany that preserve

‘Extremely satisfying’: Scientist’s insight powers new RSV vaccine for infants
Barney Graham, a former scientist at the U.S. National Institute of Allergy and Infectious Diseases (NIAID), was thrilled yesterday when
Pfizer announced encouraging results
from an experimental vaccine that could protect against a major childhood killer. In a press release, the company said immunizing pregnant women

If the full results of its clinical trial bear out that promise, the vaccine could spare millions of infants worldwide from RSV-related hospitalization, reduce lasting lung damage f...

A New Lab-Made COVID-19 Virus Puts Gain-of-Function Research Under the Microscope
On October 14, a team of scientists at Boston University released a pre-print study reporting that they had created a version of SARS-CoV-2 combining two features of different, existing strains that boosted its virulence and transmissibility. Scientists and the public raised questions about the work, which refocused attention on such experiments, and prompted the U.S. government to investigate whether the research followed protocols for these kinds of studies.
The concerns surround what is known as gain-of-function studies, in which viruses, bacteria, or other pathogens are created in the lab—either intentionally or ...

Was a study that created a hybrid COVID-19 virus too risky?
The objective was to tease apart whether Omicron’s spike protein explains why it is less pathogenic (meaning it causes less severe disease). The answer could lead to improved COVID-19 diagnostic tests and better ways to manage the disease, the preprint authors say.
Somewhat surprisingly, the hybrid virus killed eight of 10 infected mice, whereas mice infected with Omicron got sick but did not die. This suggests the mutations that make Omicron less pathogenic must involve changes in proteins other than the spike protein, the authors say.
What are critics of the study saying?
They question the scientific val...

Enhanced SARS-CoV-2 IgG durability following COVID-19 mRNA booster vaccination and comparison of BNT162b2 with mRNA-1273
: BNT162b2 (Pfizer/BioNTech, Cominarty) and mRNA-1273 (Moderna, Spikevax) are mRNA vaccines that elicit antibodies against the SARS-CoV-2 spike receptor-binding domain (S-RBD) and have been approved by the Food and Drug Administration (FDA) to combat the COVID-19 pandemic. Because vaccine efficacy and antibody levels waned over time after the two-shot primary series, the FDA authorized a booster (third) dose for both mRNA vaccines to adults in the fall of 2021.

Almost everything Tucker Carlson said about Anthony Fauci this week was misleading or false
Tucker Carlson, a political commentator on Fox News, has long assailed Anthony Fauci for his role in the U.S. government’s response to the COVID-19 pandemic during both former President Donald Trump’s and President Joe Biden’s administrations. But on 22 August, when Fauci announced he would be retiring from his jobs as director of the U.S. National Institute of Allergy and Infectious Diseases (NIAID) and chief medical adviser to the president at the end of year, the

Drought exposes ‘Spanish Stonehenge’ for study
Scientists are rushing to examine a 7000-year-old stone circle in central Spain that had been drowned by a reservoir for decades and was uncovered after the drought plaguing Europe lowered water levels. Nicknamed the “Spanish Stonehenge”—although 2000 years older than the U.K. stone circle—the Dolmen of Guadalperal (above) was described by archaeologists in the 1920s. The approximately 100 standing stones, up to 1.8 meters tall and arranged around an oval open space, were submerged in the Valdecañas reservoir after the construction of a ...

The Current COVID-19 Booster-Shot Strategy is Not Sustainable, Says FDA ’s Expert Panel
While the currently available COVID-19 vaccines remain effective in protecting people from serious disease, public health experts still face a handful of important questions about the shots and their ability to continue to protect against the virus in coming years. Will a new version of the vaccine be more effective? How long does protection last? Are boosters the only way to extend that protection? Is there a better, more coordinated way to give vaccines and boosters to maximize immunity in the face of an ever-changing virus?
Those were the discussion topics that the U.S. Food and Drug Administration’s Vaccines and ...

What to Know About a Fourth COVID-19 Vaccine Dose
Most people ages 12 and older are considered “up to date” with their COVID-19 vaccines if they received either three doses of the mRNA shots from Pfizer-BioNTech or Moderna, or two doses of Johnson & Johnson’s Janssen vaccine. But some public health experts say another dose might be needed in the coming months.
The Washington Post reports today that Pfizer and BioNTech soon plan to request authorization from the U.S. Food and Drug Administration (FDA) for a fourth dose of their vaccine in people ages 65 and older. In the past few days, Albert Bourla, Pfizer’s CEO, has said that he believes every...

FDA Authorizes COVID-19 Vaccine for Children 5-11 Years Old
COVID-19 vaccines are already authorized for children ages 12 and older, and the shots now have the backing of U.S. Food and Drug Administration (FDA) for younger children ages 5 to 11.
On Oct. 29, the FDA authorized the COVID-19 vaccine made by Pfizer-BioNTech for the youngest eligible group yet to get immunized against the disease in the US. The decision followed the recommendation from the agency’s advisory committee, which concluded in a 17 to 0 vote, with one abstention, that the vaccine was safe and effective in younger kids. For these children, the FDA is recommending a two-dose regimen at one-third the dosage...

FDA Committee Recommends COVID-19 Vaccine for Children 5-11 Years Old
COVID-19 vaccines are already authorized for children ages 12 and older, and the shots now have the support of a U.S. Food and Drug Administration (FDA) expert panel for younger children ages 5 to 11.
In a 17 to 0 vote, with one abstention, the committee recommended the COVID-19 vaccine made by Pfizer-BioNTech for the youngest group yet to potentially get immunized against the disease in the US. The committee recommended a two-dose regimen at one-third the dosage approved for adults.
The FDA now takes the committee’s advice into consideration before making a final recommendation. If the agency decides to recommend th...
