Innovations in vaccinology: Challenge and opportunities for Africa

Immunization is undoubtedly one of the most effective and most cost-effective health interventions. Vaccines continue to revolutionize our ability to prevent diseases and improve health. With all the technological advances, we are able to extend the benefits of vaccines to more people and to provide better protection from life-threatening infectious diseases. Nevertheless, thanks to the unceasing implementation of novel microbial strains on a worldwide basis, research in vaccinology must innovate continuously. African countries have made great progress in increasing routine immunization coverage rates and in introducing newly developed vaccines. New types of vaccines associated with vectorization, administration and specific licensing tools as well as with adjuvants designed to finely modulate immune responses are expected to be achieved in the near future. African countries need to work to develop a regional approach to respond effectively to the many challenges. Providing better information, implementing healthcare personnel vaccinology training programs and well targeted research projects are the keys to future achievements in the field.
