Pakistan, Afghanistan, Syria and Nigeria have something common between them other than being third world nations. They are the only remaining countries where polio, amongst other infectious but preventable diseases, still ravages and raids childhood and the dreams of an entire generation.
Vaccinations have been one of the single most effective public health interventions known to mankind but in order for a good immunisation programme to take root there needs to be a safe and stable environment to deliver the vaccinations alongside a good understanding of the political context in which these immunisation programmes operate. These countries have been in a state of conflict recently and as such, Polio triumphs along with other childhood infectious diseases.
Wars, insurgencies and conflict drive resources away from the basics such as health, education and societal structures. Ways of life are disrupted which is further compounded by forced migration, displaced populations and a breakdown of trust. It comes as no surprise then that polio’s final strongholds are some of the most complicated places in the world to deliver vaccination campaigns.
There is evidence that hostility to immunisation programmes may not necessarily be the result of insurgents’ theology, rather it arises from suspicion and mistrust. For example, in Nigeria, the last African country harbouring endemic polio, many believed that the vaccine contained anti-fertility drugs and cancer-causing viruses. Similar misconceptions were rife in Pakistan where the Taliban insurgents propagated rumours that led to the targeting and killing of healthcare workers delivering the vaccinations; such can be the indirect and uncalculated costs and victims of conflict! It did not help of course that America had used the immunisation programme as a cover up for its spying operations.
Trust is key to the acceptance and success of any public health intervention but more so for an immunisation programme that involves inoculating apparently healthy individuals with weakened strains of microbes or antibodies to the same.
Access to healthcare is a major determinant of health; war and conflict destroy the routes and health and social care structures to access so it is no wonder then that war and infectious diseases are such good comrades. Add to the picture of already exhausted and fragmented health and social care the genetic evolution of bacteria and viruses causing infectious diseases and you have a recipe for disaster that cooks for many years even after the conflict or war has ended. Lack of access to immunisation programmes, antimicrobial resistance and changing strains of microbes may have very long lasting effects that are witnessed by subsequent generations as herd immunity falls below optimal levels. Bosnia and Herzegovina being a case study in time where the recent measles outbreak was a consequence of the conflict 20 years ago.
In today’s global context, when borders are increasingly porous and diseases neither respect nor recognise these borders, the challenge posed by global conflict threatens the very premises on which our society’s foundations of health and social care have been laid. A clear example is the resurgence of polio in Iraq 14 years after being disease free due to spread from neighboring Syria.
A problem thousands of miles away does not mean it won’t come knocking on our doors soon. There needs to be a united call to arms by world leaders and all levels of society to advocate for peace, building trust and working with and through communities; something public health does best!
