Dear Dr Crystal thank you once again for this update. Regarding the VRBPAC, the link to the Novavax presentation leads to the Moderna one. I think the right link is this:

Seems to me that a sensible decision would be to aprove a KP.2 formulation for the mRNA vaccines while, at the same time, allow the Novavax JN.1. The latter appears to induce a broad Th1 protection to the FLiRT subvariants and is an option for whoever prefers a protein vaccine. This might rise communication problems (protein vs. mRNA), but the public understands that the protection spectrum may vary accross different vaccine platforms.

Thanks Manuel for the link. I agree with you about the vaccines. Part of the benefit of the mRNA vaccines is that they can be produced over a shorter time frame than the protein based vaccines. It would be better to have the next vaccine to include JN.1 + F456L mutation based antigen because that is where the virus is going and also because F456L makes it more immune evasive. I agree that the JN.1 Novavax vaccine could be offered to those who prefer it.
