alt Hacker NewsRight, that's been mentioned elsewhere.
A new area of research has opened up. This approach may be more useful for treatment than prevention. It's not really a vaccine; it's more like an induced vaccine response. Keeping the immune system in that state full time might be a problem. But after an infection, that's what's wanted.

I think that "vaccine" is really not the right word to use for this; they sound as different as bandages and blood transfusions. But if it works as advertised, it could be useful if used in the right situation.
I do wonder if the kind of people who got vaccinated 10 times against Covid-19 will end up trying to get a sniff of this every month? Kind of like how we overuse antibiotics in cleaners. It seems like it would be best if saved for an "oh shoot" kind of situation.
Some autoimmune diseases are a result of an immune system always on.
