For those who don't know WT history regarding vaccinations, in the February 4, 1931 edition of The Golden Age, p. 293, the organization decreed, "Vaccination is a direct violation of the everlasting covenant that God made with Noah after the flood."
Because of this JWs and their children often faked vaccinations for school authorities and the like. Of course, this created serious problems for JWs' health.
It also caused legal trouble for JWs who were caught disobeying compulsory vaccination laws. Not only that, but the organization itself got in trouble for requiring JWs to disobey those laws.
So on December 15, 1952, in a rare moment of candor, the organization revealed that the lawyers decided it was time for new light:
"The matter of vaccination is one for the individual that has to face it to decide for himself. Each individual has to take the consequences for whatever position and action he takes toward a case of compulsory vaccination, doing so according to his own conscience and his appreciation of what is for good health and the interests of advancing God’s work. And our Society cannot afford to be drawn into the affair legally or take the responsibility for the way the case turns out. After consideration of the matter, it does not appear to us to be in violation of the everlasting covenant made with Noah, as set down in Genesis 9:4, nor contrary to God’s related commandment at Leviticus 17:10-14… Hence all objection to vaccination on Scriptural ground appears to be lacking."
Notice, no apology to you if you or a child contracted polio as a result of obeying the WT.
Now it's come full circle. If a JW uses his or her own judgment and doesn't get vaccinations and boosters against COVID, they are in serious trouble with the organization itself.
If anyone still wonders if the Watchtower has been chosen by Jehovah to speak for him and with his authority, this complete turnaround regarding vaccinations should supply the answer.
