No it's a figure I've plucked out the air.

And it wouldn't be 1-2% for 1-2 weeks. It would be a reduction in risk of spreading for 1-2% of the population.

Probably best to use actually data in the future. We've got enough to deal with without letting our imagination do the work for us.
Because vaccination reduces transmission thus reduces virus circulation.

Vaccinations have a minimal impact on transmission and only for a matter of weeks, I do not know if it is 1, 2, 4 or another number but it is not sustained.

I've seen varying data across different studies that gives differing levels of reduced transmission which vary from strain to strain.

That was certainly not the case with Delta and although there was waning over that doesn’t appear to be clear metrics around what timeframe that is and the effect of boosters. Have not seen data for Omicron either.

Your statements seem far more definitive that the apparent evidence available.
How effective are the vaccines at preventing transmission?

A UKHSA study which looked at the Delta variant showed the COVID-19 vaccines prevent some transmission in the weeks after a jab is administered. A more recent rapid review by UKHSA of a number of other studies also concluded the vaccines provide some protection against transmission, and that for Delta this wanes substantially over time.

What did the UKHSA study show for Delta?
Effectiveness of the vaccines against transmission of the Delta variant:

After two doses of AstraZeneca: Estimated at 42%
After two doses of Pfizer: Estimated at 31%

Note: This study did not assess levels of waning over time. Studies into how well the vaccines prevent transmission of the Omicron variant are still underway.​

Nicely put.
