In a move that is garnering international attention, the head of the Catholic Church in Kenya has raised suspicions about the World Health Organization and UNICEF's tetanus vaccine campaign in their country, which is exclusively targeting over two million Kenyan women of children bearing age (14-49), to the exclusion of males and those younger who may be at higher risk from lethal harm from the tetanus infection. 
The vaccination campaign began in September of last year, is in the second of a planned three phases, and now covers 60 districts in that country. The final round is slated to begin in September of this year.
As reported on March 27th in the StandardDigital, John Cardinal Njue is alleged the WHO/UNICEF tetanus campaign has been uncharacteristically shrouded from public awareness relative to other national health initiatives that are preceded by a public launch where the public has an opportunity to ask questions. A Citizennews.co.ke news story filmed testimony of John Cardinal Njue voicing his concerns, which can be viewed here.
According to the StandardDigital report, the Catholic Health Commission of Kenya sent a statement to newsrooms on March the 26th alleging that there has not been adequate stakeholder engagement both in the preparation and implementation of the campaign. The main questions the Church raised for discussion were:
1 - Is there a tetanus crisis on women of child-bearing age in Kenya? If this is so, why has it not been declared?
2- Why does the campaign target women of 14 - 49 years?
3- Why has the campaign left out young girls, boys and men even if they are all prone to tetanus?
4- In the midst of so many life-threatening diseases in Kenya, why has tetanus been prioritized?
Additionally, the statement read:
"Information in the public domain indicates that Tetanus Toxoid vaccine (TT) laced with Beta human chorionic gonadotropin (b-HCG) sub unit has been used in Philippines, Nicaragua and Mexico to vaccinate women against future pregnancy. Beta HCG sub unit is a hormone necessary for pregnancy"
The Church's concerns are not without legitimate basis in vaccine fact and history, with previous suspicions being raised over tetanus immunization campaigns in the underdeveloped world concealing a forced 'family planning' agenda.
Not only has a birth control vaccine been known to exist for over twenty years using tetanus toxoid as a carrier,  but it was heralded in the mid-90's as "A new family planning tool to slow population growth." The development of a tetanus-based contraceptive vaccine began in 1975 by Dr. Gursaran Talwar, Director of India's National Institute of Immunology, and after $4.5 million of funding and 17 years later a working vaccine was created, whose mechanism of action has been described as follows:
"The vaccine works by "convincing" a woman's body that a11 is unchanged when, in fact, an egg has been fertilized. After conception occurs, a woman produces a hormone called human chorionic gonadotrophin (hCG) that helps to prepare the uterus for pregnancy. The prototype vaccine, made from hCG coupled to a biochemical carrier, neutralizes hCG by stimulating antibodies against the hormone. Without hCG the embryo can't anchor in the uterus, making pregnancy impossible. The biochemical carrier makes the hCG immunologically visible to women's immune system." [Source]
Additionally, in 1995, a report published in Vaccine Weekly described the case of a priest, president of Human Life International based in Maryland, who petitioned Congress to investigate reports of women in developing countries, such as Mexico, the Philippines and in Nicaragua, receiving contraceptive tetanus vaccines laced with chorionic gonadotropin (b-HCG). The report stated that the anti-fertility vaccine was developed by the World Health Organization (WHO), and other organizations including "UN Population Fund, the UN Development Programme, the World Bank, the Population Council, the Rockefeller Foundation, the US National Institute of Child Health and Human Development, the All India Institute of Medical Sciences, and Uppsala, Helsinki, and Ohio State universities."
While sparse safety research has been published on tetanus toxoid vaccines effectiveness and safety, especially when administered to pregnant women, the tetanus vaccine, when administered through the multi-antigen DTwP, which contains diphtheria, tetanus and pertussis antigens together, has been linked to a wide range of adverse health effects, including SIDS,  increased infant mortality, [4,5] Gulliain-Barre Syndrome,  and several dozen others health conditions.

At this time, allegations that the tetanus toxoid vaccine used in Kenya may contain an anti-fertility substance has not resulted in the launch of an official investigation, nor even basic testing of suspect batches of vaccine. To the contrary, there is widespread denial of the relevance of the concern, which is often the case when the known adverse health effects of vaccines are discussed within the mainstream media or health organizations, the latter of have predicated their entire mission statements and policy-making decisions on the assumption that they are highly safe and effective a priori.
At the very least, given the established dangers and ongoing controversy associated with vaccinating pregnant women, and the well-know abortive properties associated with vaccines, especially in veterinary vaccines, a red flag of caution should be raised and critical inquiry as to what the real risks and benefits of this campaign in Kenyan women of child-bearing age really are.
