The Green Our Vaccines campaign isn't about making vaccines more environmentally friendly, it's about removing toxins. Anti-vaxers, beginning to realize that their former pet thimerosal isn't a vaccine hazard, have moved to the more nebulous 'toxins' as the real danger of vaccines. Their list:It's easy to pick apart this list (sucrose in vaccines is a toxin?), as some people have done. Some of that list probably isn't even present in more than trace amounts: fetal bovine serum, for example, is a cell culture supplement for growing cells to produce vaccine not an additive to the vaccines, and it's purified out. Anti-vaxers are eager to blur the line between vaccine ingredients and components of vaccine production.
One of the items on the list is human diploid cells (from aborted fetal tissue). Sometimes this is listed simply as aborted fetal tissue. While it's understandable that people might not want to inject themselves with aborted fetal tissue (though, I'm not sure it's necessarily toxic), there are still a couple of problems with that inclusion on the list:
1) Vaccine makers aren't grinding up aborted fetuses and injecting them. Nor are they generating new fetal cell lines from them every time a vaccine is made. The 'human diploid cells (from aborted fetal tissue)' are one of two cell lines derived in the 60s and 70s: WI-38 and MRC-5.
2) These cell lines aren't ingredients. They are used to produce viruses used for vaccines. They are removed during the production process (a simple spin will separate the cells from the virus-rich supernatant, which is then further processed). That needs to be stressed, because it applies to many of the "toxins" on the list: tools used for production of vaccines aren't ingredients.
Of course there is a potential moral objection to the use of aborted fetal cells in production, even if they aren't in the vaccine itself. The Catholic Church, for example, encourages the use of alternative vaccines where they exist and to press pharmaceutical companies to develop such alternatives. However even the Church, which is normally rigid in its stance, allows the use of vaccines derived from fetal cells in the absence of an alternative. This is made clear in their official position: "we find, in such a case, a proportional reason, in order to accept the use of these vaccines in the presence of the danger of favouring the spread of the pathological agent, due to the lack of vaccination of children." They go even further than this with regards to the German measles vaccine, adding
This is particularly true in the case of vaccination against German measles, because of the danger of Congenital Rubella Syndrome. This could occur, causing grave congenital malformations in the foetus, when a pregnant woman enters into contact, even if it is brief, with children who have not been immunized and are carriers of the virus. In this case, the parents who did not accept the vaccination of their own children become responsible for the malformations in question, and for the subsequent abortion of foetuses, when they have been discovered to be malformed.That having been said, the stand taken by the 'Green Our Vaccines' group does not seem to stem from moral objections, but rather they're clear that it's about the fearful toxins. It seems that they're either unsure of how vaccines are produced or willfully misusing charged words (eg. aborted human fetus) to drum up vaccine opposition.
Soylent green may be made out of people, but vaccines aren't.
