Sterilizing vaccines inhibit spread. The SARS-CoV-2 vaccines aren't sterilizing to any significant extent. Vaccinated individuals might be contagious for a slightly shorter period but in the long run that doesn't matter because the virus is now endemic and everyone will be exposed eventually. Fortunately the vaccines are still fairly effective at preventing deaths.
Country-level anecdata is basically useless without a multi-factor analysis due to huge differences in restrictions and self-directed prevention by the public.
