Modified vaccinia virus Ankara as vaccine vectors in human and veterinary medicine

Abstract

ABSTRACT:  Disease prevention through vaccination is one of the most important achievements of medicine. Today, we have a substantial number of vaccines against a variety of pathogens. In this context, poxviruses and vaccinology are closely related, as the birth of modern vaccinology was marked by the use of poxviruses as immunogens and so was the eradication of smallpox, one of the world's most feared diseases ever. Nowadays, poxviruses continue to notoriously contribute to vaccinology since their use as vaccine vectors has become popular and widespread. One of the most promising vectors is the modified vaccinia ankara. In this review we provide an overview of the contribution of poxvirus to vaccine immunology, particularly focusing on modified vaccinia ankara-based vaccines developed to date.
