Postmodernity and global polio eradication

Polio is getting closer to being eradicated. If it happens, it would join (along with smallpox among humans and rinderpest among cattle) that very rare class of pathogens that have been taken literally out of circulation by conscious human efforts.  That sounds good, but in the case of polio it also shows just how long it takes medical advances to deeply penetrate resource-limited and politically volatile settings: a safe and effective vaccine has already been around for half a century. In any case, due to the collective efforts by charitable organizations, civil society, government and religious leaders, Nigeria is getting nearer to being rid of polio, and tomorrow will mark a year since a case of polio has been diagnosed there. The remaining holdouts are Pakistan and Afghanistan. But potential threats to polio eradication may lie elsewhere, where you rationally would expect it less.

Like California. According to the California Department of Public Health, over 60% of children in the state have not received the full suite of vaccinations. This is partly a case of being victims of their own success: Americans have little experience of what it is like to be prey to infectious agents precisely because vaccines have worked so well on so many of them. It is a stance you have the luxury of taking from a position of relative privilege. But it is partly due also to a culture of gossip, suspicion and kneejerk mistrust of medical authority, and hence also from a position of ignorance. If vaccines are the product of Enlightenment faith in reason and science to improve society, rejection of vaccines -- when not itself based on sound reasoning and evidence -- is regression into a pre-scientific state where life was nasty, brutish and short. Privilege and ignorance is a toxic combination, and some people have to (re-)learn the hard way.

Pneumoccal vaccine in Africa: one step forward, one step back?

It is pretty well known that many routine medical interventions in the world's more affluent countries make infrequent appearances -- or sometimes none at all -- in the world's poorer ones. The publicly-financed health care systems in some sub-Saharan Africa look to be decades behind the United States, Canada or the United Kingdom when it comes to devices, drugs and procedures. For that reason, initiatives that seek to close the gap are, in principle, to be welcomed. Oftentimes, however, these initiatives are accompanied by moral baggage.

Take for instance the launch of a new pneumoccal vaccine among children in Africa. Considering the number of childhood deaths attributable to pneumonia in this part of the world, the effort has an initial air of nobility. Many lives will be saved, many illnesses avoided. But if one looks more closely, serious ethical problems seem to emerge. There are two multinational pharmaceutical companies involved in the campaign -- GlaxoSmithKline and Pfizer/Wyeth -- who have agreed to sell 30 million doses every year for ten years at $10.30 per child vaccinated. These companies also stand to each gain $225 million in subsidies through their involvement in this scheme. Doctors Without Borders worries that this price for vaccination is very high for many countries, and that the lock on the market exercised by GSK and Pfizer/Wyeth will strongly discourage local companies from developing cheaper generic equivalents. The companies are establishing their brand under favorable circumstances to themselves; after that, all bets are off.

Some people argue that pharmaceutical companies should be given incentives to focus greater attention on developing countries, otherwise they will simply develop whatever is likely to sell to richer consumers elsewhere. But the pneumoccal vaccine example can make you think twice about the wisdom of 'incentivizing'. In the short term, many children will be vaccinated. But in the long term, unless prices are made to go down, children of wealthy elites within developed countries are most likely to benefit. The usual pattern threatens to repeat itself: big business wins, the higher classes win, and the rest struggle on.

Delivering vaccines in Africa: some unethical obstacles

The attention and money thrown at the H1N1 virus seems to grow by the day, even if the numbers of H1N1 related deaths, relative to other causes of mortality (including plain old seasonal flu), are still very modest. People actually die from H1N1, so it is not nice to make light of it, and because it is contagious, the death toll will rise, though we don't know how high or for how long. Nevertheless, there is no way of getting around the impression that the world's media is drawn to the latest viral threat to the richer developed nations, where the knight in shining armour is played by multinational pharmaceutical companies, whose cutting-edge research thankfully produces the latest vaccine, while the media makes rapid and widespread vaccination seem like the only rational response, and governments and local health agencies stand to be criticized for not getting vaccines into bodies fast enough. The significance of the H1N1 virus as a threat to humanity? Only time will tell. But that a great deal of money is being made: that is already certain.

Elsewhere in the world, other fish are frying. Forget new cutting-edge research for new diseases: in many countries, it is hard enough just to get the old vaccines administered, for the boring old diseases, the ones that people in developed nations hardly get anymore because they are routinely vaccinated against them. Take measles. Two troubling stories about measles vaccination in Africa came in this week.

First, here in South Africa, some media sources managed to revive the discredited measles-autism link, i.e. that the measles vaccine causes autism in children. A little media ethics for journalists working on public health issues could go a long way, and hopefully these incidents will not cause setbacks for measles eradication in South Africa, similar to the problems with polio vaccination in Nigeria some years back. The recent decline in measles mortality in Africa is a success story, but only conserted and sustained efforts (including communication of accurate health information) will keep those numbers going down.

Second, in the Democratic Republic of Congo, measles vaccination efforts face an unusual adversary: government troops. Medecins Sans Frontieres (Doctors without Borders) has accused the Congolese government of using their vaccination sites as bait. Due to a measles epidemic, MSF was vaccinating thousands of children in sites locations that are controlled by the Forces Democratique de Liberation du Rwanda (FDLR) . Knowing that people in the area would gravitate to the opportunity for measles vaccination, Congolese government troops apparently attacked all seven sites with deadly force, scattering populations (including children) into the bush. It remains to be seen if people in the area will trust going back to MSF sites for medical care, and in this troubled part of the world, that is about the only decent medical care around.
