VSS Scientific Updates During Pandemic Times #42
1. The Next U.S. COVID Wave is Coming.Why it Will be 'much weirder than before.'
Experts call this “convergent evolution” — and right now, there’s a “fairly unprecedented amount” of it going on, according to Tom Peacock, a virologist at Imperial College London.
“Although stuff started off in different places — someBA.2, some BA.5 — everything’s going back in the same direction,” Peacock recently told Stat. “They’re getting the same mutations, which implies there’s a very strong selective pressure in the environment right now, which of course is people’s immunity.”
2. Virological Characteristics of the SARS-CoV-2 Omicron BA.2.75 Variant
“Antiviral drugs largely retained potency but antibody sensitivity varied depending on several key BA.2.75-specific substitutions. TheBA.2.75 spike exhibited a profoundly higher affinity for its human receptor,ACE2. Additionally, the fusogenicity, growth efficiency in human alveolar epithelial cells, and intrinsic pathogenicity in hamsters of BA.2.75 were greater than those of BA.2. Our multilevel investigations suggest that BA.2.75acquired virological properties independent of BA.5, and the potential risk ofBA.2.75 to global health is greater than that of BA.5.”
3. With Fall Migration, Bird Flu Flies Back into Town
But by all other measures, this year’s outbreak is “radically different than what we’ve seen before,” said Bryan Richards, the emerging disease coordinator at the National Wildlife Health Center, which is part of the U.S. GeologicalSurvey.
4. Posts Mislead on Pfizer COVID Vaccine’s Impact on Transmission
“WhileRoos and many others framed this as a new revelation, Pfizer never claimed that its clinical trial, upon which the vaccine was authorized for use, evaluated the shot’s effect on transmission. In fact, shortly before the vaccine’s release, the company’s CEO emphasized that this was still being evaluated.”
5. The Real Anthony Fauci: The Movie
“Within the first 5 minutes, you know why Robert F. Kennedy Jr.’s blockbuster bestelling book The Real Anthony Fauci is now a full-length feature documentary exposing Big Pharma, Big Tech and Big Government.”
