Article Synopsis
  • The introduction of direct-acting antivirals (DAAs) offers hope for eliminating hepatitis C virus (HCV) by 2030, but some patients (2%-12%) experience treatment failure, potentially due to existing drug resistance.
  • A systematic review of 56 studies found a high prevalence of hepatitis C resistance-associated substitutions (RAS) among patients with virological failure after DAA treatment, ranging from 78% to 100% depending on the specific treatment regimen.
  • The findings highlight the importance of monitoring DAA-associated resistance and understanding its implications for future treatment strategies.

Radiation-attenuated sporozoite (RAS) vaccines can completely prevent blood stage Plasmodium infection by inducing liver-resident memory CD8 T cells to target parasites in the liver. Such T cells can be induced by 'Prime-and-trap' vaccination, which here combines DNA priming against the P. yoelii circumsporozoite protein (CSP) with a subsequent intravenous (IV) dose of liver-homing RAS to "trap" the activated and expanding T cells in the liver.

Background: Plasmodium knowlesi is an established experimental model for basic and pre-clinical malaria vaccine research. Historically, rhesus macaques have been the most common host for malaria vaccine studies with P. knowlesi parasites.

Malaria is caused by parasites and was responsible for over 247 million infections and 619,000 deaths in 2021. Radiation-attenuated sporozoite (RAS) vaccines can completely prevent blood stage infection by inducing protective liver-resident memory CD8 T cells. Such T cells can be induced by 'prime-and-trap' vaccination, which here combines DNA priming against the circumsporozoite protein (CSP) with a subsequent intravenous (IV) dose of liver-homing RAS to "trap" the activated and expanding T cells in the liver.
