Fig. 2From: Combining serological and contact data to derive target immunity levels for achieving and maintaining measles eliminationMisclassification error (MCE) as a function of the threshold level of for contact-adjusted or plain immunity. Dots give the mean MCE at the tested threshold levels, connected by a line to guide the eye. The grey shades indicate a standard deviation around the mean (uncertainty coming from both the serological sample and from the contact sample)Back to article page
