Herd Immunity to COVID-19 and Pre-existing Immune Responses

By Nic Lewis – Re-Blogged From WUWT

I showed in my May 10th article Why herd immunity to COVID-19 is reached much earlier than thought that inhomogeneity within a population in the susceptibility and in the social-connectivity related infectivity of individuals would reduce, in my view probably very substantially, the herd immunity threshold (HIT), beyond which an epidemic goes into retreat. I opined, based on my modelling, that the HIT probably lay somewhere between 7% and 24%, and that evidence from Stockholm County suggested it was around 17% there, and had been reached.

I then showed in a July 27th update article[1] that mounting evidence supported my reasoning.

Human Trial Suggests CRISPR Could Be a Viable Cancer Treatment

By Kristin Houser – Re-Blogged From Futurism

This could be great news for experimental cancer treatments.

Scientists from the University of Pennsylvania just published the results of the first U.S. trial of CRISPR-edited cells in cancer patients — and they’re very encouraging.

In April 2019, UPenn confirmed that a team of its researchers had officially begun testing CRISPR-edited cells in humans.

For that trial, the scientists had removed immune cells from three patients with advanced, treatment-resistant cancers. They then used CRISPR-Cas9 to edit the cells in order to improve their ability to fight tumors before returning them to the patients’ bodies.

Scientists Discover Immune Cell That Kills Most Cancers

By Kristin Houser – Re-Blogged From Futurism

“Previously nobody believed this could be possible.”

A newly discovered immune cell could lead to the creation of a universal cancer treatment — a “Holy Grail” treatment that would work for all cancers, in all people.

The treatment leverages T-cells, a type of white blood cell that helps our bodies’ immune systems by scanning for and killing abnormal cells. For background, scientists have recently started harnessing that ability in the fight against cancer through a therapy called CAR-T, which involves removing T-cells from a patient’s blood and genetically engineering them to seek out and destroy cancer cells.

Meet the Carousing, Harmonica-Playing Texan Who Just Won a Nobel for his Cancer Breakthrough

Re-Blogged From Wired

Chance favors the prepared mind. —Louis Pasteur
James Allison looks like a cross between Jerry Garcia and Ben Franklin, and he’s a bit of both, an iconoclastic scientist and musician known for good times and great achievements. He also doesn’t always answer his phone, especially when the call arrives at 5 am, from an unfamiliar number.So when the Nobel Prize committee tried to reach Allison a few weeks ago to inform him he’d been awarded the 2018 Nobel Prize in medicine, Allison ignored the call. Finally, at 5:30 am, Allison’s son dialed in on a familiar number to deliver the news. The calls have not stopped since.
