JEHOVAH’S WITNESSES
Jehovah’s Witnesses have historically been against vaccination because it is contrary to scriptures, and their religion totally banned it up until 1952, although in more recent years they have stated it is up to the individual Jehovah’s Witness to decide: "As vaccination is a direct injection of animal matter in the blood stream, vaccination is a direct violation of the law of Jehovah God." (The Golden Age publication, 1935 April 2 p. 465).
"Oh, yes, serums vaccines, toxins, inoculations, are all -harmless', because the man who is selling them says so. You, my friends, believe this LIE, and continue to submit your body to these violations; then all I can say is, 'God have mercy on your soul'. All vaccination is unphysiological, a crime against nature." (Consolation 1939 May 31 p. 8).
‘Would it be proper to accept a vaccination or some other medical injection containing albumin derived from human blood? Witnesses have long realized (Interesting wording - not "the GB", but "Witnesses" realized - does that mean that Witnesses are able to realize things on their own) that this is a matter for private decision in accord with each one’s Bible-trained conscience. Some Christians who feel that they can in good conscience accept such injections have noted that antibodies from the blood of a pregnant woman cross into the blood of the baby in her womb.” (The Watchtower, October 1, 1994).
The reason for this about turn? In 1952, when Jehovah’s Witnesses lifted the ban on vaccination, they wrote: "The matter of vaccination is one for the individual that has to face it to decide for himself. . . . And our Society cannot afford to be drawn into the affair legally or take the responsibility for the way the case turns out." (my emphasis – The Watchtower, 15 December 1952).
Essentially they still disagreed with vaccination but were too afraid of the medical profession taking legal action against them.
