Evaluation of a Zika virus-like particle-based vaccine in a highly penetrant non-human primate model of congenital infection - PubMed
Zika virus (ZIKV) is an arthropod-borne Orthoflavivirus that caused a major outbreak in Central and South America in 2015-16. During that outbreak, ZIKV infection during pregnancy was associated with high rates of adverse outcomes, including miscarriage and a spectrum of neurological birth defects c …

Combination therapy with broadly neutralizing antibodies, antiretroviral therapy and CCR5 blockade limits viral reservoir seeding in infant macaque model of HIV - PubMed
Lack of access to antiretroviral therapy (ART) leads to the transmission of human immunodeficiency virus in ~120,000 children annually, emphasizing the need for new strategies to prevent lifelong infection. Here in an infant rhesus macaque model of peripartum oral infection, we show that broadly neu …
