According to health policy experts felt that governments and societies must implement revolutionary changes in their approach to vaccines and preventive medicine if they want to ensure the health and welfare of their citizens. Rino Rappuoli, Henry J. Miller, and Stanley Falkow, felt that vaccination is considered the most effective medical intervention and there has never been a better time than the present for vaccine development and implementation, write.
However, the future of vaccination as a preventative strategy is uncertain, and there is not a great deal of enthusiasm about vaccine development among those who actually have the capability to develop and produce vaccines.
The researchers attribute much of the problem to the lack of economic incentive for pharmaceutical companies to produce new vaccines or even maintain adequate supplies of existing ones. Pressure from governments to keep the costs of vaccinations low so more people around the world can receive them may actually be counterproductive, because industry must make a profit in order to provide the service.
Rappuoli, Miller, and Falkow suggest more needs to be done on a worldwide basis to promote the use of vaccines and the development of new vaccines, with rich countries leading the way through economic incentives. They also believe a fruitful effect from better immunization of children in poor countries could be less terrorism. Despair for one's lost children is a powerful tool to recruit new terrorists or to appeal to those who are discontent with their government.
