Hi TWIV,
The spike component of BA.4 and BA.5 is the same. The differences are outside the spike. So when FDA says BA.4/5 spike, they are both the same thing.
Since BA.5 is the one that’s spreading, it would be less confusing for them to say the updated vax should be 50/50 Wildtype/BA.5
PS thanks for the great podcast!
Brianne, Brianne, Brianne. What have you done to me? Redactle is now on my bookmark bar and I’m hooked after only two days. (Actually I was hooked after my first effort.) Thanks.
