The answer to your question is in the article. This is not an attenuated virus, nor is it variolation, it's a modified other virus (common cold) with some proteins added and does not cause an infection, it just stimulates antibodies. It has been heavily modified, first so it cannot cause infections in people and also to make it "look" more like coronavirus. Scientists did this by transferring the genetic instructions for the coronavirus's "spike protein" - the crucial tool it uses to invade our cells - to the vaccine they were developing.

It's just the common cold, and the side effects are currently only a headache and fever, so getting the vaccination virus secondhand would be better than getting coronavirus, and you'd be protected after.

  Common colds can occasionally be serious for people who are severely immunocompromised in other ways.

The problem is not the vaccine, it is when you actual contract COVID-19 later on. If the vaccine sufficiently suppresses the symptoms, but doesn't actual prevent infection, there is a change you can spread the virus asymptomatically.

  I see how that's important. On the other hand, it's not as big of a deal to spread the virus if everyone has protection from the symptomatic risks. We should still shelter in place, but even turning active cases into carries would reduce loss of life (presuming we continue regular testing so people can KNOW if they are a carrier)

How do you think they'd behave knowing that they've been vaccinated? It's important to consider the sociological conditions in which an intervention is deployed. Unfortunately, our present society has a very large number of self-centred individuals.

  This is a great way to turn the anti-vaxxers, hahah. The more people take the vaccine, the less society bothers to social distance and other low-tech things, the more dangerous not taking the vaccine becomes.
