White Paper: Why We Still Have Polio

PROFESSOR’S NOTE: Later in the course, you’ll be asked to produce a White Paper on your chosen research topic. Today, for our fourth reading, I offer you this model of what I hope your own White Papers will be. Like this one, yours will be work-in-progress toward an actual paper, and will organize your thinking for your own benefit and the benefit of early reviewers such as me.

When you’ve read it, and perhaps after some classroom discussion about it, choose a subtopic or small claim in the White Paper you’d like to research and find one strong source using Google, Academic Search Premier, or any web-searching database or engine you’re comfortable using. Publish a new post to identify that source and how what it contains either supports or refutes a claim, or how it contributes to a thesis you find worthwhile.

Polio (short for poliomyelitis) is an infectious disease that rarely kills but cripples about 1 in 200 of its victims. The virus invades the nervous system and can lead to irreversible paralysis in just hours. Adults fight off the infection more effectively than children, most often children younger than five. There is no cure, but there have been safe and effective vaccines for more than 50 years. By their nature, vaccines need only be administered once to be effective for a lifetime, so the strategy to eliminate polio once and for all from the planet is to vaccinate every child until transmission stops. If the world can be made polio-free for a moment, it will remain polio-free forever.

The virus enters the body through the mouth, multiplies in the intestine, and is passed to others through the feces; therefore, it ravages particularly countries with poor sanitation and hygiene. Children not well toilet-trained are a danger, but even flies can passively pass the virus from feces to food. A single case of polio, if it fails to migrate to other vulnerable children, can die out in that community forever. Complicating matters, most infected individuals show no symptoms and can silently pass the virus on unwittingly until it dies out in their bodies naturally. Therefore, a single reported case is usually taken as evidence of an epidemic.

A simple, inexpensive, oral vaccination developed in 1961, admininsterable by non-physician volunteers, is the primary method of preventing polio among children. The vaccination produces antibodies in the blood to all three types of poliovirus which prevent the virus from spreading to the nervous system. A single dose costs less than a dime. In a community where the polio virus would be spread through feces contact, so can the immunization be passively spread through the same mechanism. A single dose protects most recipients. Three doses protects 95% of recipients, probably for life. 100% immunity, while ideal, is not necessary to eradicate the virus, which will naturally die out if it cannot spread through a population.

In about 1 case per 3 million, the vaccine virus can itself cause paralysis. (A current theory is that paralysis results in recipients with existing immune deficiencies.) This risk, while devastating, is “accepted” by administering agencies as a necessary cost of saving “hundreds of thousands” of children each year from crippling.

Polio was a most feared disease in industrialized countries, paralyzing thousands of children every year, until the development of vaccines in the 1960s and the beginning of routine immunization in countries around the world. From the Global Polio Eradication Initiative website:

In 1988, when the Global Polio Eradication Initiative began, polio paralysed more than 1000 children worldwide every day. Since then, 2.5 billion children have been immunized against polio thanks to the cooperation of more than 200 countries and 20 million volunteers, backed by an international investment of more than US$ 8 billion. Today, polio has been eliminated from most of the world and only four countries remain endemic. In 2009, fewer than 2000 cases were reported for the entire year.

What bad news does that terse report hide? The four endemic countries are Afghanistan, India, Nigeria, and Pakistan. But four other countries no longer on the endemic list have re-established active and persistent transmissions following an importation: Angola, Chad, Democratic Republic of Congo, and Sudan. Add to that the countries currently experiencing outbreaks due to importation (Congo, Kazakhstan, Liberia, Mali, Mauritania, and 8 others including Russia) and the challenge of containing the virus long enough to eradicate it becomes obvious.

Polio is a perfect candidate for eradication because the virus infects only humans, is carried in the body for a short period of time, and has an effective intervention. “We have great vaccines against polio,” says Harry Hull, chief of the World Health Organization’s (WHO’s) Polio Eradication Program. The WHO-led campaign uses the oral “Sabin” vaccine because it is cheap–8 cents a dose–can be easily administered by mouth by an untrained volunteer, and produces high levels of intestinal immunity.

An editorial in the journal Lancet, SEP 2006, indicates that polio vaccination campaigns have met with distrust in communities over the years. Incorrect but understandable fears that mass vaccination is a conspiracy by the developing world against poor countries complicate the efforts of volunteers to conduct one-day mass immunization efforts which have been the most effective part of the WHO plan for years. Just as important as funding, volunteers, and sufficient doses, is building trust among poor and often suspicious people through sustained efforts.

One early morning, millions of people across India, from the snow-peaked Himalayas to the deserts of Radjastan, set off by foot, camel, bike, car, or helicopter to run polio vaccination posts in 650,000 Indian villages. By the time this army of volunteers arrived home at the end of the day, 127 million children under the age of 5 had been immunized against this crippling disease. “Everybody said it just couldn’t happen. And, yet it does,” says Harry Hull, chief of the World Health Organization’s (WHO’s) Polio Eradication Program. Initiatives such as the Polio Eradication Program show that WHO’s foot soldiers can make a huge difference to the majority of the world’s population without adequate health care.

At first, the campaign to rid the world of a disease that has left some 10 million to 20 million people paralyzed did not seem to be making an impact. But in 1995, WHO and its partner, the United Nations Children’s Fund (UNICEF), adopted the new strategy of blitzing the entire child population of a country in a single day. In 1996, such National Immunization Days vaccinated more than 420 million children–almost two-thirds of the world’s children under five–against polio. These dramatic campaigns captured the imagination of the world and have even persuaded hardened fighters in war-torn countries such as Afghanistan, Sudan, and Sri Lanka to stop fighting for a day so that their children can be immunized.

By the end of 2003, international effort had eliminated polio from all but 6 countries in the world. In the 6 remaining countries, the disease was highly localized. But a series of misunderstandings about the safety and intentions of the vaccinators shut down the campaign, caused a nationwide epidemic, and led to reinfection of many polio-free countries. For the first time in history, more countries suffered importations of polio than were actually endemic for the disease, putting the entire eradication initiative at risk.

In Kano, northern Nigeria, local leaders began theories that the vaccine contained HIV and anti-fertility agents. Very soon, the local media were reporting the popular conspiracy theory that the polio campaign was an effort to depopulate the north of the country. Within months, political leaders in Kano and adjoining states had suspended the polio campaigns; almost immediately, hundreds of children had been paralyzed as epidemic polio returned. The virus rapidly spread from Kano to the megacity of Lagos and beyond, reinfecting polio-free countries, costing over US $100 million in emergency response activities. One of Africa’s most impressive achievements in health and international cooperation was undone by a rumor.

On January 15, 2004, the leaders of the World Health Organization and UNICEF met with the health ministers of the 6 remaining polio-infected countries and 3 of the recently reinfected countries to issue the Geneva Declaration on the Eradication of Poliomyelitis, stating that 2004 presented the best, and possibly last, chance to achieve this global public good. The declaration introduced an aggressive plan to immunize a total of 250 million children during door-to-door polio immunization campaigns in each country within the next 12 months. The Nigerian minister outlined an extensive program of joint work with Kano state authorities to resolve the remaining doubts about the safety of the polio vaccine and then allow the resumption of the polio immunization campaigns. In 2011, polio still exists in the world. Is now, once again, our “best, perhaps last, chance” to eradicate the disease?

From JSPN (Journal for Specialists in Pediatric Nursing) A decade ago, a British researcher and 12 coauthors published a paper describing abnormal gastrointestinal features among 12 children who had been referred to their clinic. All children had some type of developmental disorder, and in 9 of the children, a diagnosis of autism had been made. In 6 of the 9 autistic children, either the parent or a physician had linked the onset of developmental regression with the receipt of the MMR vaccine for measles, mumps and rubella (Wakefield et al., 1998). In 2000, a second paper was published, in which measles virus RNA fragments were found in 3 of the 9 children. (Kawashima et al., 2000). This odd, tiny, substantially anecdotal evidentiary link is the basis for fears persisting until today that somehow measles vaccinations cause autism.

In 2004, 10 of the 11 coauthors of Wakefield’s original paper asked to “formally retract the interpretation placed upon these findings . . .” However, these initial reports of a possible relationship between the MMR vaccine and the onset of autism received significant attention, and in England, measles vaccinations dropped considerably.

A brief query of Rowan’s MEDLINE database yields 232 results for a simple search “smallpox eradication.” I suspect I’ll be able to find adequate historical information to support the theory that if any infectious disease can be eradicated from the planet (as smallpox was), then polio can be.

If there’s a class difference between polio and smallpox that interferes with this conclusion, I may be able to devote one of my smaller papers to detailing that difference, either to minimize it or to recommend a different approach for eradicating polio than was successful for smallpox.

Regarding the successful eradication of smallpox from the planet, an article in the May 8, 2010 Lancet offers insight I may need to use.

Force was, of course, sometimes used to achieve immunisation targets…. Organised and violent resistance during epidemics could provoke ferocious responses from vaccination teams…. Opposition to vaccination was widely regarded as being dangerous to communities in regions that had been freed from the scourge, and this was seen as sufficient justification for the use of compulsion. Compulsory vaccination schemes were implemented with the assistance of police and paramilitary forces which had considerable societal support.

The thrust of my research continues to convince me that the effort to once and for all eradicate polio from the planet is a worthwhile and achievable global good. Despite excellent arguments to the contrary (1. that the money could be used to alleviate more suffering more immediately by attacking less recalcitrant diseases; 2. that human beings will never universally accept the necessity and efficacy of the effort and will therefore sabotage the effort; 3. that eradication is a myth since new strains will always replace the old before the old dies out), I will propose continued and even stepped-up efforts to eliminate this virus from the planet once and for all.

I feel strongly that the tiny risk of transmitted paralysis to one child in 3 million is “acceptable,” God forgive me for saying so. I also insist that it might be necessary to compel the reluctant last however-many-thousands to submit to vaccination against their wishes. I recognize the moral dilemma, but think it might be forgivable to lie about that tiny risk if to do so put a rumor to rest that threatened the entire program.

There is much reading yet to do. Topics I’ll be investigating include the success rates of various vaccines (there are four); more opinions on the origins of the Nigerian rumor (there are many); details of the life-cycle of the poliomyelitis virus (when will we know it’s really, really gone for good?); ancillary techniques for immunization (can we use bad sanitation to our advantage?). I love the counterintuitive result that immunization can be spread accidentally the same way the virus is spread!

Understand that my White Paper today is a snapshot of a work-in-progress and entirely acceptable on those terms. It’s not aimless by any means; there’s a good bit of rigor in the categories and the details of my report so far; but it’s not at all complete. And that’s OK. And it will be OK for yours too when it’s time for you to write one (so long as I see some rigor, and very little aimlessness).

    After using Google to find more research, it led me to http://www.cdc.gov where i researched the effectiveness of vaccine.

    “A 1916 polio epidemic in the United
    States killed 6,000 people and paralyzed 27,000
    more. In the early 1950’s there were more than
    25,000 cases of polio reported each year. Polio
    vaccination was begun in 1955. By 1960 the
    number of reported cases had dropped to about
    3,000, and by 1979 there were only about 10.
    The success of polio vaccination in the U.S. and
    other countries has sparked a world-wide effort
    to eliminate polio.”

    This claim describes the effectiveness of vaccine throughout many years of experience. over time in history the vaccine became more effective, reducing the number of cases of polio. It shows that people who might have polio should get the vaccine to keep the numbers of cases down still.
