Is this mRNA, live weakened virus, or dead virus? Last time I read an article on this vaccine it wasn’t made clear.
I don’t think this one is mRNA.
J&J took a more classic approach it’s not MRna they took a coronavirus that causes the common cold and taught it to use the same spike proteins as it’s pandemic brother. They are giving you a cold which teaches your body to make the specific killer antibodies to the real Sars covid II. This is the way vaccines have been made for.decades. it’s the same idea and method used to wipe smallpox off the planet. Polio as well. This is the version that anyone who.understands science should want.
It is an attenuated dna? I þhink.
The Johnson & Johnson (AKA Jansen) does not use an mRNA approach.
It uses a well known, harmless adenovirus as the carrier, of an identifying spike protein from COVID-19. That is a traditional, conventional approach.
This is the same technical approach as the AstraZeneca/Oxford vaccine, and the Russian Sputnik V.
The big news in this article, is the 90% effectiveness rate. We have been waiting for them to publish that result.
That’s a great number, and the fact that they are reporting it publicly, means that the Phase 3 trial analysis is wrapped up, and they are moving to request Emergency Use Authorization. I believe that Dr. Fauci stated he expects it at the end of next week.
Hopefully, they can ramp up production. Recent reports indicated that they were off to a slower start then hoped - Perhaps just a few million doses in February, and then ramping up over March.
It is a one shot vaccine, and does not require challenging cold storage.
This apparenty used fetal tissues in its development
“Adenoviruses are common viruses that usually cause cold-like symptoms, but because the one used in the vaccine was altered and cannot replicate, it can’t make you sick. “
I don’t like quoting Hollywood in serious matters, but the familiarity of that statement is a harbinger of the potential problems with vaccines developed with genetically modified viruses.
Other FReepers are grossly mistaken in comparing this vaccine to Polio, etc. IMHO, had Fauci et al cured AIDS with an adenovirus-type vaccine - or ANY other disease, for that matter - perhaps I would give more weight to this development. They have the burden to prove this biotechnology not only works, but is safe. Introducing it in the middle of a manufactured crisis to be administered to the entire population does NOT automatically grant a pass in my book.
More night table reading if you’re curious as to the science behind this new type of ‘vaccine’...

Not exactly either, as I understand it. (China’s is the only claimed-to-be totally traditional dead virus version I’ve noticed.)
At least sounds better to me until I think that it is especially being positioned for Africa and other third-world environments. Somehow given Gates’s record there I don’t trust it.
