Allergic reactions to Moderna’s COVID-19 vaccine are extremely rare, report finds

Moderna’s COVID-19 vaccine rarely causes severe allergic reactions, according to new data released by the Centers for Disease Control and Prevention (CDC). Between Dec. 21 and Jan. 10, more than 4.04 million people were given Moderna’s COVID-19 vaccine, but only 10 developed a serious, potentially life-threatening allergic reaction called anaphylaxis. That works out to be […]

COVID-19 vaccines may cause allergic reactions in 1 in 100,000 jabs

Serious allergic reactions after  COVID-19 vaccines are likely more common than serious reactions following flu vaccines, but are still very rare, according to a new report. The report authors, from the Centers for Disease Control and Prevention (CDC), analyzed data from the first 1.9 million doses of COVID-19 vaccine administered in the U.S. from Dec. […]

Severe allergic reactions to COVID-19 vaccines are rare, CDC says

Out of the first 1.9 million doses of Pfizer’s COVID-19 vaccine administered in the United States, there were 21 reported cases of severe allergic reactions to the vaccine, the Centers for Disease Control and Prevention said January 6. The rate of anaphylaxis seen so far — 11.1 cases per 1 million vaccine doses — is […]

Allergists offer reassurance regarding potential allergic reactions to COVID-19 vaccines

BOSTON – Reports of possible allergic reactions to the COVID-19 vaccines produced by Pfizer-BioNTech and Moderna, both recently approved for emergency use by the U.S. Food and Drug Administration (FDA), have raised public concern. A team of experts led by allergists at Massachusetts General Hospital (MGH) has now examined all relevant information to offer reassurance […]

Researchers discover C-H bond activation reactions at low temperature by photo-induced means

Chemical reactions related to the breaking and further synthesis of the C-H bond require high activation energy and poor selectivity. Therefore, it’s important to understand […]

What’s causing rare allergic reactions to Pfizer’s vaccine?

Public health officials are investigating the cause of several severe allergic reactions that were reported among hundreds of thousands of people vaccinated with the Pfizer-BioNTech coronavirus vaccine last week.  As of Friday (Dec. 18), six people who received the jab in the U.S. developed anaphylaxis, or a severe allergic reaction that can be life-threatening if […]

Researchers perform chemical reactions in levitating solvent

This floating solvent can be used for chemical reactions

Using ultrasonic standing waves, researchers levitate droplets of solvent, which can be used for chemical reactions. Running chemical reactions requires a an awful lot of glassware. For labs without a dishwasher, the cleaning and management of dirty glassware can be a massive source of friction. No one enjoys discovering that a reaction can’t be run […]

What you should know about allergic reactions to the COVID-19 vaccine

In the United States, most people who have serious allergies can get immunized but are advised to discuss it with their doctor first. (Unsplash/) Two healthcare workers in Alaska developed allergic reactions within minutes of receiving Pfizer’s COVID-19 vaccine, The New York Times reported on December 16. Both of the afflicted people worked at Bartlett […]

Scientists encapsulate catalyst in a protective molecular sieve that selectively prevents undesired reactions in methanol fuel cells — ScienceDaily

Because of the many environmental problems caused by the use of fossil fuels, many scientists worldwide are focused on finding efficient alternatives. Though high hopes have been placed on hydrogen fuel cells, the reality is that transporting, storing, and using pure hydrogen comes with a huge added cost, making this process challenging with current technology. […]

The discovery of abnormal chemical reactions may lead to novel targets for drugs that treat neurodegenerative diseases — ScienceDaily

A new study on Alzheimer’s disease by Scripps Research scientists has revealed a previously unknown biochemical cascade in the brain that leads to the destruction of synapses, the connections between nerve cells that are responsible for memory and cognition. The findings present a fresh angle for discovering drugs that treat Alzheimer’s disease, which affects roughly […]
