This is one of the latest papers I was shared with by the Oxford email comms: https://www.tandfonline.com/doi/full/10.1080/14760584.2022.2092472

>"The most-studied COVID-19 vaccines provide consistently high (>90%) protection against serious clinical outcomes like hospitalizations and deaths, regardless of variant"

>"We found that the three most-studied vaccines, BNT162b2, mRNA-1273, and AZD1222, had a high and comparable overall VE against symptomatic infections (average >77%)"

This paper was a review of 79 separate real-world studies into vaccine efficacy in several countries ("Most of the data (28 studies) were from North America where BNT162b2 was the most-studied vaccine, followed by mRNA-1273 and AZD1222")

Seems to find that the 3 major vaccines (Pfizer, Moderna and Oxford/Astra-Zeneca) were broadly comparable and all provided around 90% protection against serious outcomes and 77% overall protection against infection, which they say was comparable across all three. The tables and figures in the paper break it down more into useful categories that I won't attempt to type up in here :)
