Are there any traditional (attenuated) COVID vaccines in the works? What is their status?

I ask because several of my vaccine-hesitant relatives say they would take a COVID shot that works like a traditional vaccine, with a live, dead or attenuated virus. I believe them because they are not anti-vaxxers in general and had no problem with checking if their immunizations for things like MMR and TDAP were up to date before my son was born.

I found an article about one such candidate, a nasal vaccine that is currently in trials. But it seems like this is years away from becoming a reality. There's a vaccine with EUA in India, Covaxin, that seems to be a more traditional vaccine, but with my limited scientific knowledge I am not sure. My understanding is that Covaxin was denied an EUA and told to apply for full approval because there were enough vaccines already with EUA. If Covaxin is a more traditional vaccine, I think that is a big mistake on the part of the FDA, because at least some people would take the COVID shot if a more traditional vaccine were available.

Does anyone know if any other attenuated COVID vaccines are in the works or available in other parts of the world?
