"Covishield" is actually the Oxford/AZ vaccine; its called covishield in India for reasons known only to the Serum Institute; regardless of that, it is the OXFORD/AZ vaccine, with all credit to the researchers at Oxford.
The studies on the Oxford vaccine are published in the Lancet. However, there are further studies based on vaccination in the UK including real world data from the SIREN study.
COVAXIN is only approved in India and phase 3 results have NOT been peer reviewed/published as far as I can tell.
India is only using the Oxford/AZ vaccine and the Bharat Bio vaccine.
