Direct intranodal tonsil vaccination with modified vaccinia Ankara vaccine protects macaques from highly pathogenic SIVmac251

Abstract

Mucosal surfaces are a primary route of HIV entry, yet the compartmentalisation between mucosal and peripheral immune systems remain a challenge for HIV vaccine candidates. Authors utilise a combination of intranodal tonsil MALT and systemic vaccination in the rhesus macaque model to explore immune responses and protection from highly pathogenic simian homologue of HIV.
