Are you willing to get the Covid vaccine when offered?

That's just the point, I already did...
You seem to be repeatedly assuming that vaccination doesn't affect infectiousness and transmission. But the evidence indicates that it does. E.g. for a recent study, see:

That's in line with earlier studies, such as those referenced by the COVID-19 vaccine surveillance reports from the UK Health Security Agency (https://www.gov.uk/government/publications/covid-19-vaccine-weekly-surveillance-reports) which indicate a limited but significant effect on infection and transmission, reduced by waning over time (and hence increased again following boosters).

People generally seem to be constantly jumping to absolute interpretations, where it's all or nothing, and lumping "limited but significant" with "none". But those aren't the same thing and that's not the reality. The evidence indicates that vaccination does have an effect on transmission, and therefore, people who have been keeping up to date with their vaccinations are, overall, less likely to have been infectious than people who haven't.
