Jenner Institute, University of Oxford, UK
J Infect Dis 208:340-5. 2013..We find that the parameters estimated by these models are closely correlated, and their predictive accuracy for omitted data points was similar. We propose that future studies include the linear model...

- Substantially reduced pre-patent parasite multiplication rates are associated with naturally acquired immunity to Plasmodium falciparumA D Douglas
Jenner Institute, Nuffield Department of Medicine, University of Oxford, UK
J Infect Dis 203:1337-40. 2011..This supports the view that a blood-stage vaccine capable of emulating the disease-reducing effect of natural immunity could achieve a detectable effect during the prepatent period...
