Fig. 2: Schematic of parameters to be estimated using serosurveillance platform (shown in red, blue and gold).
From: Using sero-epidemiology to monitor disparities in vaccination and infection with SARS-CoV-2

Red represents the probability of vaccination given prior infection, Pr(vacc|inf), blue represents the probability of prior infection, Pr(inf), and gold represents the probability of vaccination given no prior history of infection, Pr(vacc|uninf).
