My parents didn't take the vax, Dad is an elder, and neither did some of the other elders and their families.
Trust in the GB is selective, but they don't see how odd that looks when they go along with practically everything else. I can't understand it myself.
I think they just kept very quiet about their non compliance, made no waves in the cong.
That same cong had a guest speaker earlier this year comparing the vax to Jesus' ransom sacrifice and those refusing the vax are like those refusing Jesus' sacrifice, oh the irony!
