Though Delta continues to be the dominant COVID-19 strain, the World Health Organization (WHO) now says there's a new variant to keep your eye on. The B.1.621 variant, also called Mu, has just been listed by the WHO as a new "variant of interest" as of August 30. © Provided by Health.com New COVID Variant [...]
Being fully vaccinated against Covid-19 not only cuts the risk of catching it, but also of an infection turning into long Covid, research led by King's College London suggests. It shows that in the minority of people who get Covid despite two jabs, the odds of developing symptoms lasting longer than four weeks are [...]
Moderna Inc.’s Covid vaccine generated more than double the antibodies of a similar shot made by Pfizer Inc. and BioNTech SE in research directly comparing immune responses to the inoculations. A study of almost 2,500 workers at a major Belgium hospital system found antibody levels among individuals who hadn’t been infected with the coronavirus [...]
A coronavirus variant first detected in South Africa 'could be more infectious' than other mutations and have the potential to 'evade vaccines', scientists have said. The C.1.2 strain, which is linked to 'increased transmissibility', is more mutations away from the original virus seen in Wuhan, experts at South Africa's National Institute for Communicable Diseases and the KwaZulu-Natal Research Innovation [...]
The mutation rate of SARSCoV2 is at least 50% higher than previously thought. The virus mutates about once a week—significantly higher than the rate estimated previously. UK findings suggest new variants could emerge sooner than earlier estimated. Owing to a lag between a deleterious mutation’s appearance and its selective removal, gold-standard methods for mutation [...]
An artificial neural network (AI) designed by an international team involving UCL can translate raw data from brain activity, paving the way for new discoveries and a closer integration between technology and the brain. The new method could accelerate discoveries of how brain activities relate to behaviors. The study published today in eLife, co-led by [...]
Protection against the coronavirus is waning among those who have received both shots of the AstraZeneca and Pfizer vaccines, a new U.K. study has found. An analysis from the U.K.’s ZOE Covid app study of over 400,000 people who had received both shots of the Pfizer-BioNTech vaccine, showed that it was 88% effective in protecting against [...]
In a significant step forward in understanding the crucial role tissue-resident memory T (TRM) cells play in the immune system, researchers have for the first time described how the cells behave in different tissues around the body. This discovery adds to the growing knowledge base around the huge potential of T cell-based vaccines, including [...]
We’re approaching the year-and-a-half mark of the globe’s collective experience with the SARS-CoV-2 virus and the Covid-19 pandemic it has triggered. At this point, it’s fair to assume people the world over are asking themselves the same two questions: How will this end? And when? There may have been a fleeting chance humans could [...]
Pfizer CEO Albert Bourla said on Tuesday that he believes it is 'likely' that a strain of COVID-19 could emerge that is resistant to vaccines. However, the pharmaceuticals boss claimed that the company would be able to develop a new shot to tackle a vaccine-resistant strain within 95 days of its emergence, Fox News reported. 'Every time that a variant [...]
