But not particularly great compared to Covishield (Oxford-AZ) and Covaxin which are the main vaccines in use in India. The fancy needle free injector is almost certainly going to be more expensive than a normal syringe and will make logistics more difficult. While the thermal stability is great, I don't think it will be a game changer. The one thing it has going for it is that it can be given to children above 12.

I couldn't find the effectiveness of Covishield against Delta but for Covaxin the claimed efficacy is in the same ballpark at 65%. So this is not bad at all.

Perhaps it is easier to apply than injections. Rural India may not have qualified medical personnel.

Not qualified enough for intramuscular injections and paperwork? It doesn't seem likely. Fancy injectors might have advantages: less expensive, more expensive (in a corrupt enough setup), more compact, faster to use, physically or chemically better, but novelty itself makes them less easy to use.
