Alternatives to conventional vaccines - Mediators of innate immunity

Vaccines have been described as weapons of mass protection. The eradication of many diseases is testament to their utility and effectiveness. Nevertheless, many vaccine preventable diseases remain prevalent because of political and economic barriers. Additionally, the effects of immaturity and old age, therapies that incapacitate the adaptive immune system and the multitude of strategies evolved by pathogens to evade immediate or sustained recognition by the mammalian immune system are barriers to the effectiveness of existing vaccines or development of new vaccines. In the front line of defence against the pervasiness of infection are the elements of the innate immune system. Innate immunity is under studied and poorly appreciated. However, in the first days after entry of a pathogen into the body, our entire protective response is dependant upon the various elements of our innate immune repertoire. In spite of, its place as our initial defence against infection, attention is only now turning to strategies which enhance or supplement innate immunity. This review examines the need for and potential of innate immune therapies.

Alternatives to peace keeping in Korea: the role of non-state actors and face-to-face encounters

Korea is one of the world's most volatile areas, not least because traditional UN mediation and peacekeeping missions are impossible. Having intervened in the Korean War on behalf of the southern side, the UN is a party to the conflict, rather than a neutral arbiter. The situation is particularly problematic because political interactions are characterized by a high degree of state-control over security policy. In both parts of the peninsula the state has, at least until recently, exercised the exclusive right to deal with the opponent on the other side of the hermetically divided peninsula. Given these domestic and international constrains, alternative approaches to conflict resolution are urgently needed. The recently proliferating literature on human security offers possible solutions, for it urges policy makers to view security beyond the conventional military-based defence of the state and its territory. Using such a conceptual framework, the essay assesses the potential significance non-state interactions between North and South, particularly those that promote communication, information exchange and face-to-face encounters. Even though these interactions remain limited, they are of crucial importance, for they provide an opportunity to reduce the stereotypical threat images that continue to fuel conflict on the peninsula.
