| SvennoJ said: I guess BA.2.75 would be a good bet to focus on for fall. We're dealing with BA.4 and BA.5 currently, too late to adjust vaccines for that now, 2.75 will probably take over after the summer wave is done. |
BA.2.75 is not distinct enough from either BA.1 or BA.2 to warrant a vaccine of its own.
As for the second point, that might not be true for India - it had a massive BA.2-exclusive wave (which is close to BA.4/5) and a massive Delta wave last year. The L452R mutation in BA.4/5 was not only present, but antigenically dominant in Delta.
