The race to curb the spread of Covid vaccine disinformation

The race to curb the spread of Covid vaccine disinformation

Nature reports: In March, Twitter put its foot down: users who repeatedly spread false information about COVID-19 vaccines will have their accounts suspended or shut down. It was a new front in a high-stakes battle over misinformation that could help to determine how many people get vaccinated, and how swiftly the pandemic ends. The battle is also being fought in computer-science and sociology labs across the United States, where scientists who track the spread of false information on social media…

Least vaccinated U.S. counties have something in common: Trump voters

Least vaccinated U.S. counties have something in common: Trump voters

The New York Times reports: About 31 percent of adults in the United States have now been fully vaccinated. Scientists have estimated that 70 to 90 percent of the total population must acquire resistance to the virus to reach herd immunity. But in hundreds of counties around the country, vaccination rates are low, with some even languishing in the teens. The disparity in vaccination rates has so far mainly broken down along political lines. The New York Times examined survey…

Doctors hone in on cause of blood clots potentially linked with Covid-19 vaccines

Doctors hone in on cause of blood clots potentially linked with Covid-19 vaccines

CNN reports: Doctors say they are honing in on the cause of blood clots that may be linked with certain coronavirus vaccines, and add their findings have important implications for how to treat the condition, regardless of whether vaccines cause it. Even though the link is not firm yet, they’re calling the condition vaccine-induced immune thrombotic thrombocytopenia or VITT. It’s characterized by unusual blood clotting combined with a low number of blood-clotting cells called platelets. Patients suffer from dangerous clots…

The blood-clot problem is multiplying

The blood-clot problem is multiplying

Roxanne Khamsi writes: For weeks, Americans looked on as other countries grappled with case reports of rare, sometimes fatal blood abnormalities among those who had received the AstraZeneca vaccine against COVID-19. That vaccine has not yet been authorized by the FDA, so restrictions on its use throughout Europe did not get that much attention in the United States. But Americans experienced a rude awakening this week when public-health officials called for a pause on the use of the Johnson &…

America’s corn belt has lost a third of its topsoil

America’s corn belt has lost a third of its topsoil

Becca Dzombak reports: Seth Watkins has been farming his family’s land in southern Iowa for decades, growing pasture for his cows as well as corn and other row crops. His great-grandfather founded the farm in 1848. “He came in with one of John Deere’s steel plows and pierced the prairie,” Watkins recounted. With its rolling hills and neat lines of corn stretching to the horizon, broken by clumps of trees, it’s a picturesque scene. But centuries of farming those hills…

Pfizer CEO says third Covid vaccine dose likely needed within 12 months

Pfizer CEO says third Covid vaccine dose likely needed within 12 months

CNBC reports: Pfizer CEO Albert Bourla said people will “likely” need a third dose of a Covid-19 vaccine within 12 months of getting fully vaccinated. His comments were made public Thursday but were taped April 1. Bourla said it’s possible people will need to get vaccinated against the coronavirus annually. “We need to see what would be the sequence, and for how often we need to do that, that remains to be seen,” he told CNBC’s Bertha Coombs during an…

The mRNA vaccines are looking better and better

The mRNA vaccines are looking better and better

Sarah Zhang writes: A year ago, when the United States decided to go big on vaccines, it bet on nearly every horse, investing in a spectrum of technologies. The safest bets, in a way, repurposed the technology behind existing vaccines, such as protein-based ones for tetanus or hepatitis B. The medium bets were on vaccines made by Johnson & Johnson and AstraZeneca, which use adenovirus vectors, a technology that had been tested before but not deployed on a large scale….

Why would a Covid vaccine cause rare blood clots? Researchers have found clues

Why would a Covid vaccine cause rare blood clots? Researchers have found clues

STAT reports: A week after receiving the AstraZeneca Covid-19 vaccine, a 37-year-old woman in Norway went to the emergency department with fever and persistent headaches. A CAT scan of her head showed a blood clot in blood vessels involved in draining the brain, but her levels of platelets, involved in clotting, were low. She was treated with platelet infusions and a blood thinner, but had a bleed in her brain the next day. She underwent surgery to relieve the pressure…

The U.S. media is touting Israel’s Covid recovery. But occupied Palestinians are left out

The U.S. media is touting Israel’s Covid recovery. But occupied Palestinians are left out

Yara M Asi writes: The US media has widely lauded Israel’s vaccine success – as a country in a “post-pandemic future” of concerts and indoor dining; as a country that could teach the United States a few lessons in pandemic management; as a country that, despite being in the midst of a contentious election, leaned on its robust universal public health system to vaccinate as many people as possible. However, many of these vaccine success stories mention the issue of…

First GMO mosquitoes to be released in the Florida Keys

First GMO mosquitoes to be released in the Florida Keys

By Taylor White This spring, the biotechnology company Oxitec plans to release genetically modified (GM) mosquitoes in the Florida Keys. Oxitec says its technology will combat dengue fever, a potentially life-threatening disease, and other mosquito-borne viruses — such as Zika — mainly transmitted by the Aedes aegypti mosquito. While there have been more than 7,300 dengue cases reported in the United States between 2010 and 2020, a majority are contracted in Asia and the Caribbean, according to the U.S. Centers…

Sweden’s pandemic experiment

Sweden’s pandemic experiment

Mallory Pickett writes: Sweden’s per-capita case counts and death rates have been many times higher than any of its Nordic neighbors, all of which imposed lockdowns, travel bans, and limited gatherings early on. Over all in Sweden, thirteen thousand people have died from covid-19. In Norway, which has a population that is half the size of Sweden’s, and where stricter lockdowns were enforced, about seven hundred people have died. It’s likely that some simple policy changes—especially shutting down visitations to…

As vaccinations keep rising, so do Covid-19 hospitalizations among those who aren’t vaccinated

As vaccinations keep rising, so do Covid-19 hospitalizations among those who aren’t vaccinated

CNN reports: First, the good news: The United States reported a record-high 4.6 million doses of vaccines administered in one day, according to data published Saturday by the Centers for Disease Control and Prevention. “Amazing Saturday! +4.63M doses administered over total yesterday, a new record,” tweeted Dr. Cyrus Shahpar, the White House Covid-19 data director. “More than 500K higher than old record last Saturday. Incredible number of doses administered.” The problem is that more than 75% of the US population…

For immigrants, IDs prove to be a barrier to a dose of protection

The Washington Post reports: The line started outside, on a street usually teeming with people waiting to enter college bars, and snaked up the stairs of an old firehouse to the Brazilian Worker Center, where shots of the coronavirus vaccine were being administered on this cold New England spring morning. Finally, it was Maria Sousa’s turn. She had been waiting for more than an hour with her husband and daughter when a center volunteer greeted them in Portuguese and guided…

Official: Chinese vaccines’ effectiveness low

The Associated Press reports: In a rare admission of the weakness of Chinese coronavirus vaccines, the country’s top disease control official says their effectiveness is low and the government is considering mixing them to get a boost. Chinese vaccines “don’t have very high protection rates,” said the director of the China Centers for Disease Control, Gao Fu, at a conference Saturday in the southwestern city of Chengdu. Beijing has distributed hundreds of millions of doses abroad while trying to promote…

The pandemic’s terrible toll on kids: ‘All of the people I look up to, they are all, like, breaking down’

The pandemic’s terrible toll on kids: ‘All of the people I look up to, they are all, like, breaking down’

The Wall Street Journal reports: When Victoria Vial’s Miami middle school shut down last spring and her classes went online, it felt like the beginning of an adventure. “I was in my pajamas, sitting in my comfy chair,” the 13-year-old recalled. “I was texting my friends during class.” Then she received her academic progress report. An A and B student before the pandemic, she was failing three classes. The academic slide left her mother, Carola Mengolini, in tears. She insisted…
