Also, yes, the Novavax vaccine works via the asshole protein. This time, instead of mRNA or viral vectors, they just made the asshole protein itself. But how they did that was kind of cool.
They took the gene code for the asshole protein and put it in a different virus. Then they made that virus infect a bunch of moth cells in a lab.
So now you’ve got a ton of infected moth cells that are producing asshole proteins.
Then they harvest up all the asshole protein from the weird moth cell factory farm.
Bam! Fresh locally made asshole protein in large supply!
Gather those asshole proteins in bunches and tie them together with a really small particle and you’ve got yourself a vaccine!
Well, almost.
These proteins aren’t on a virus, and they’re not being produced by your cells, it’s possible your body will just ignore it or not make a big deal out of it.
Enter the adjuvant.
Adjuvants are sometimes part of vaccines to stimulate the immune response.
They’re not the main event. They’re the asshole protein’s hype man. They’re just there to get the immune system’s attention & pump up the crowd response so your body remembers the protein better.
Adjuvants tend to be a target for anti-vaxxers so it’s worth knowing what’s in this vaccine. It’s an extract from a soapbark tree. The story’s pretty cool to read about. (Warning: if you think my Twitter threads are long, hoo boy, grab a coffee.) theatlantic.com/science/archiv…
Anyways, the same as Pfizer, Moderna, J&J, AstraZenica, Sputnik... the Novavax vaccine contains no coronavirus & you can’t get COVID from it.
In this case, it’s the asshole protein and its hype man. Not the virus.
The vaccine seems to work really well. 89% effective in its phase 3 trial so far. Two doses. Don’t need super cold temps to store.
The South Africa mutation though seems to have enough changes to the asshole protein that Novavax is less effective against it but still does provide some protection. Also, even then, it seems to protect against severe infection. Novavax is working on a new booster if necessary.
And now, looks like we may be producing it in Canada as early as this summer (pending delays, b/c there’s always delays). Should help in that summer/fall push to get everyone vaccinated. ALSO, helpful to have a domestic producer of booster shots for variants if necessary.

Not all are approved yet but it looks like we’ll have at least a half dozen vaccines going around in various parts of the world soon enough.
As expected, each has their own pluses and minuses.
Pfizer & Moderna (mRNA): best efficacy results so far, but need 2 doses, transport at low temps. Won’t have enough for the world (like all the vaccines). Pfizer with 2 billion & Moderna with 1 billion doses or so by the end of 2021.
AstraZenica (viral vector): So far studies suggest not as effective as the mRNA ones but still very good. Two doses. Don’t need super low temps. Said they’d have 3 billion doses in 2021, not sure if that’s still true.
I didn’t get a chance to comment on this more the other day, but we are absolutely seeing this surge of anorexia in Saskatoon over the last 6 months or so.
In some ways, it’s almost reassuring to see it’s happening elsewhere too. Initially we were wondering if it was just us.
Anorexia is probably the deadliest mental illness you can get for children & adolescents. The mortality rate is high and since it usually hits teens, it takes out kids who shouldn’t be dying of anything at their age. So it’s serious stuff.
They mostly die from two causes:
1) Heart problems
See, if you’re really underweight, you don’t have much left to burn for energy other than muscle.
Your heart is a muscle.
So if you’re low enough in weight, your heart will literally shrink in size. You’re burning it for fuel.
What the Merck vaccines tried to do was combine the asshole protein on to a weakened live virus (not the COVID virus, in both vaccines it was a different virus). So basically this guy, but with the asshole protein spliced in.
That’s different than the AstraZenica vaccine, which gives you the asshole protein instructions in an empty shell of a virus that doesn’t replicate in your body.
The Merck ones put it in a weak virus that CAN replicate in your body.
China recently approved the Sinovac vaccine and since apparently this is what I do in my spare time now, let’s talk about how that one works!
It works in yet a different way than the mRNA (Pfizer / Moderna) or the AstraZenica vaccines.
The Sinovac vaccine is a more traditional vaccine type. It’s an “inactivated” vaccine. That’s different from another traditional vaccine type: an “attenuated” vaccine.
I should take a moment to clarify the difference.
Think of an “attenuated” vaccine (also sometimes called a “live” vaccine) is when you take a virus and make it way less dangerous. It’s basically your body fighting against this guy.
