Holding the Polio Vaccine Hostage

Since the development of the vaccine, perhaps the most effective public health measure we have yet devised, only one human disease has been completely eradicated from the world – smallpox. The last case was reported in Somalia in 1977. Eradication was the result of a deliberate and intense campaign, requiring almost complete vaccination of the population, especially in certain population dense areas. Countries such as India and Nigeria were among the last to achieve eradication. Some of the lessons learned were that very high compliance rates were needed and that even small communities could harbor the virus and prevent eradication.

Several decades later, at the beginning of the 21st century, we are on the verge of eradicating a second major human infectious disease, polio. Like smallpox, polio is a virus that has no major non-human host, so eradication is possible. The polio virus enters the anterior horn cells of the spinal cord, the lower motor neuron – cells that connect the brain to muscles. When those cells die muscles lose their connection causing weakness and atrophy. Vaccine campaigns have successfully eliminated polio from most countries, but the wild type of the virus remains endemic in Nigeria, India, Pakistan, and Afghanistan.

We have the potential, with one final push (which is being spearheaded by the World Health Organization – WHO) to eradicate wild type polio from the world, but these efforts are being hampered by politics and ideology.

WHO Partnering with Traditional Healers in Africa

There is an AIDS epidemic in Africa, and efforts to fight it are hampered by the endemic social problems of that continent. Chief among them are the lack of sufficient modern health resources, the spread of destructive rumors and myths about HIV/AIDS, and even the persistence of HIV denial in Africa (although this last factor is better than in the past).

The World Health Organization (WHO) and the International HIV/AIDS Alliance are teaming up with the Traditional Health Practitioners Association of Zambia (THPAZ) to address the first problem – the lack of health services. Most Zambians use traditional healers for primary health care. The WHO has therefore decided to utilize traditional healers in the fight against AIDS. There are interesting pros and cons to this policy, but it must first be recognized that there is no ideal solution to the problem. The resources to provide optimal modern health care to treat and prevent HIV/AIDS (which would need to include a massive education program) in Zambia and the rest of Africa simply do not exist. One might argue that the world should provide those resources, but let’s put that issue aside and focus on what to do in the meantime.

The arguments given in favor of this WHO strategy are:

Traditional healers far outnumber biomedical workers in the rural areas.

They are consulted, not only because they are closer and more affordable than their Western-trained counterparts, but also because they are embedded, extensively and firmly, within Ugandan culture.

Traditional healers are highly respected and widely consulted by communities.
