I think we shouldn't extrapolate the general performance of MRNA vaccines from the COVID ones. It's the first time they have been widely used and the other vaccine technologies don't really offer any more long term protection, so it might have more to do with COVID than the technology.

It's fair to be skeptical considering that influenza does indeed also change frequently, but as always, research is needed and will show whether these claims hold up.
