Russia and China both use similar tech, an adenovirus vector, to the Oxford/AZ vaccines.
Personally, even though mRNA vaccines are completely novel, I'd prefer one of those even if efficacy were similar. Open question when or if FDA will approve this. They are submitting based on international data, with less numbers than the mRNA studies, after already having a long safety pause.
