> Read an article on cdc's website that the "effectiveness" of flu shots fluctuates between 10 and 60%. I really doubt any of these covid vaccines do better.
Flu has an additional problem of having high immunity evasion (corona doesn't show that nearly as much) so it's always a guess, whether vaccine will be effective against viruses that will evolve over the next season.
> do the vaccinated test positive for covid?
PCR: no
RAT: I believe most of those detect the nucleocapsid, not the spike protein which is in the vaccine, and even then RAT swap is from the nose and vaccine isn't nasally administered, so again no
