A Twitter post from Covid researcher Yunlong Cao claims that Omicron BA.2.75.2 is “currently the most immune evasive strain we have tested so far”.

Yunlong Cao is a co-author of the recent preprint “Characterizations of enhanced infectivity and antibody evasion of Omicron BA.2.75” which we covered in this post.

As of 8th September 2022, the research data from Yunlong Cao on BA.2.75.2 hasn’t yet been finalized or published. We will update this post when we have more news.
