Today there is a lot of hope placed in a vaccines to immunise against Covid 19 , and relief that they are soon to be available. That will be shared by the eight million or so JWs in this world.
They should be thankful that the WTS has moved away from its teaching ,that lasted for decades , proclaiming that vaccination was wrong, and a tool of Satan. ....e.g.
Golden Age 1921 October 12 p.17
"Vaccination never prevented anything and never will, and is the most barbarous practice...We are in the last days; and the devil is slowly losing his hold, making a strenuous effort meanwhile to do all the damage he can, and to his credit can such evils be placed...Use your rights as American citizens to forever abolish the devilish practice of vaccinations."
Golden Age 1931 February 4 p.293
"Vaccination is a direct violation of the everlasting covenant that God made with Noah after the flood."
And an illustration in Golden Age May 1939
I am advised that it was not until the 1950s that the policy was changed and “new light “ allowed them to make their own personal decision. I have not seen any negative comments in my experience.
So, their are millions of Witnesses who should be glad that the belief changed. After all it is not just the Covid vaccine. All the childhood jabs we had for protection against such things as diphtheria, polio, MMR etc. Foreign travel would not be available to them without the required inoculations against tropical diseases..
You know, I would bet the vast majority of them are blissfully unaware of this strange doctrine in their past......
