I have been traveling and working a bit until the last couple of days, so this somehow slipped by radar.
We have a new vaccine coming out, NovaVax.
Here is the most plain English description of how it works: https://www.nebraskamed.com/COVID/moths-and-tree-bark-how-the-novavax-vaccine-works
Here is a more detailed article: https://www.sciencemag.org/news/2020/11/will-small-long-shot-us-company-end-producing-best-coronavirus-vaccine
Long story short:
The Novavax method uses moth cells to make spike proteins:
[ol]
Researchers select the desired genes that create certain SARS-CoV-2 antigens (spike protein). Researchers put the genes into a baculovirus, an insect virus. The baculovirus infects moth cells and replicates inside them. These moth cells create lots of spike proteins. Researchers extract and purify the spike proteins. [Researchers add turbo-boost for vaccine made from soapbark tree] [/ol]
Why I am hopeful:
1) Just as effective as mRNA and adenovirus vaccines.
2) There is no DNA reprogramming going on in your body. The spike protein is manufactured in the moth's body, not yours
3) This is a better known technology with a longer history. Similar technology was used to develop a Hep B vaccine that has been part of the routine vaccinations for kids since the early 1990's
Protein Subunit Vaccine:
That is what NovaVax is. Basically, you just take the part of the virus that creates the immune response, and inject it into the patient. It's different than a killed virus or an attenuated virus vaccine, in that you don't have the entire virus injected, only the part that creates an immune response.
About the only lucky thing for us about COVID is that the protein that causes the immune response sticks out like a sore thumb (its da spike, duh).

Fun fact, the moth cell model used to make the vaccine was developed by an Aggie class of '83.
Why I will likely not get the vaccine: I'm immune. I got sick, and then got better. I don't need it.
Why I might go ahead and get the vaccine: they might be able to tailor make this sucker to follow the virus mutations around the spike protein. ie, they might be able to make a vaccine that is targeted to new variants as they pop up
Would I give this vaccine to my teenage kids? No. They are not really at risk.
The phase 3 data looks very, very good. I'm hoping this thing hits mass production soon.
I did ask my mom and dad to both schedule T-cell tests. They believe they had COVID, but I'm not sure. If those come back negative, I will recommend them getting this one, for sure.
