There was a point in time UK zoom AA meetings were demanding proof of vaccination to attend virtual meetings....you might be able to find a pdf of the 2021 rules. I don't care what mantra they preach alongside this, the support of the jab and the authoritarian takeover is unforgivable....believe what you want, their are some non UK/EU meetings that are still pretty good, and even US based meetings that are good, but UK ones are a dumpster fire.
