AI Thread Summary
The discussion centers on the genetic coding used by various COVID-19 vaccines, specifically Moderna, Pfizer, Johnson & Johnson, and AstraZeneca, in relation to the spike protein they target. It is noted that while these vaccines utilize the spike protein to elicit an immune response, the genetic codes may not be identical. Pfizer, Moderna, and Johnson & Johnson are based on a prefusion stabilized, membrane-anchored full-length spike protein developed by researchers at UT Austin. AstraZeneca's approach differs, utilizing a viral vector to deliver the spike protein. The conversation references early research that identified the spike protein, which was crucial for the development of these vaccines. Additionally, there are mentions of safety concerns regarding the Johnson & Johnson vaccine, which has faced a temporary pause due to reports of rare blood clotting events. Overall, the vaccines share a common target in the spike protein but differ in their genetic approaches and mechanisms.

TL;DR Summary
Are Moderna/Pfizer/JJ using the same genetic code to make the spike?
Given the variants of the corona virus now appearing, I was wondering,

Are Moderna, Pfizer and Johnson and Johnson and Astrazeneca all using the same genetic code to create the spike protein?
Or more specifically, the spike protein that's made by our body, is it the identical spike protein in all these four vaccines?

I hope this question makes sense?

I'm not sure whether the genetic codes used are exactly the same, but for Pfizer, Moderna, and J&J they should be effectively the same as they are based on a prefusion stabilized, membrane-anchored SARS-CoV-2 full-length spike protein from Jason McLellan's group at UT Austin.

Recommendation to Pause Use of Johnson & Johnson’s Janssen COVID-19 Vaccine
Updated Apr. 20, 2021
Print
What you need to know:
The use of Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 Vaccine is paused for now. This is because the safety systems that make sure vaccines are safe received a small number of reports of people who got this vaccine experiencing a rare and severe type of blood clot with low platelets.
Seek medical care right away if you develop any of the symptoms below.
If you have any questions at all, call your doctor, nurse, or clinic.

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
