I doubt there will ever be a vax for a flu/cold virus...they mutate so quickly you always be behind the curve. They are still giving vaxes for last years Covid strains that don’t exist any more...that’s like getting last years flu shot for this years flu...it’s pointless, unless you goal is to make money.
You can’t fix stupid.

18 months ago someone here told me that developing a vaccine was hopeless for this virus...he was right.
