respinal··on Oxford-AstraZeneca coronavirus vaccine approved for use in UK
> some participants routinely swabbed themselves for SARS-CoV-2 testing, even if they weren’t showing symptoms. Differences in infection rates between people who received the placebo and those who got the Oxford vaccine suggest the vaccine blocks transmission, says Ewer. (The Pfizer and Moderna trials tested only people who showed symptoms.)

Yes. "COVID-19 vaccination should be offered to you regardless of whether you already had COVID-19 infection." https://www.cdc.gov/coronavirus/2019-ncov/vaccines/faq.html

Exactly. "BREAKING—95%—new data from Oxford/AstraZeneca vaccine shows 95% efficacy & is “100% effective” in preventing severe Hospital illness, says AZ CEO. That’s on par w/ Moderna & Pfizer. No official data yet, but UK said to likely approve in days." https://twitter.com/DrEricDing/status/1343047055078551554?s=...

Probably. I read it first in Spanish from the BBC https://www.bbc.com/mundo/noticias-54429012 and also found the one that someone quoted here from the New York Times.

respinal··on Ask HN: Can you program B cells to make antibodies for viral spike proteins?
You are welcome!

For #1, I totally agree, used B cells as an example, and also implantable devices/sensors could bring more challenges (foreign body response, encapsulation, a big issue for implantable sensors). I am thinking more of a new virus detector that can be used in vitro or outside that can automatically adapt to viral changes (mutations). Let's call it "molecular morphing" virus detector, if you will (https://www.researchgate.net/figure/Principles-of-the-molecu...).

For #2, sweet! Thanks for sharing! The new virus detection platform could be used to create personalized vaccines, yes.

For #2.1, oh. Software can definitively do things faster like try million iterations until they find the "perfect match" or strong bond (from my previous comments) for viral spike proteins.

For #2.2, also agree, I am more interested in the detection/screening side of things for diseases in general.

respinal··on Ask HN: Can you program B cells to make antibodies for viral spike proteins?
Yes, but not better per se. I would say more adaptive or controllable (which is probably very hard to do). Nature/biology has been doing that by trial and error for years, but it takes time and it is not very efficient.

I am more interested in #2 as this could significantly improve and make robust detection/sensing systems, since viruses constantly mutate changing the binding affinities of detection/sensing systems. My background is in bioanalytical chemistry, so as soon as I read about the commonality of viral spike proteins among viruses that idea crossed my mind.

Definitely, the human body is a complex system. So if you block the viral spike protein of a virus (e.g., SARS-CoV-2), that could have some adverse effects in some people? Interesting.

Thank you for your comments! Very helpful!

respinal··on Ask HN: Can you program B cells to make antibodies for viral spike proteins?
Thank you for your reply! I was asking more specifically, could not write it due to characters limitation, about programming B cells (or any antibody generating system) to make antibodies to target viral spike proteins (peplomers), in an interactive or dynamic way (changing as virus mutates) , until a strong bond is reached/found (e.g., YES/NO decision). I was reading that most viruses have viral spike proteins, so if someone could do that it would be great for the treatment and detection of viral infections. Also, it could save a lot of time and money.
respinal··on Ask HN: How did you learn about 3D printing?
Yes, the CAD part is the first step. Fusion 360 has a version that you can use for free for one year (https://www.autodesk.com/products/fusion-360/personal). Fusion is very user-friendly. Depending on your 3D printer, you can 3D print a picture (2D to 3D). Mine has that option (https://www.youtube.com/watch?v=Vic6PkCgYk8), so you basically can use Microsoft Word or any program to make your design. The only issue could be the dimensions, but if it is for fun then it is OK. Also, look for any picture and 3D print it.
respinal··on Ask HN: How did you learn about 3D printing?
I basically used YouTube videos, forums (https://www.3dhubs.com/knowledge-base/how-design-snap-fit-jo...), and the instructions from the 3D printer's company. I have this one in my lab: https://www.flashforge.com/product-detail/4. I started with something very simple and only one filament. Then, did something more complex with two filaments. I have some videos here: https://randyfespinal.wixsite.com/randyespinalcabrera/3d-pri... If you are familiar with Fusion 360 or any CAD software, that helps a lot. I love fusion 360.
