data(variantData)

variantData is a data.frame containing 30,000 participants The data.frame contains 10 columns,

ID: A unique patient identifier.
X1: A dichotomous baseline covariate; generated from B(0.5).
X2: A continuous baseline covariates; generated from N(45,10^2).
E: The entry time into the study.
A: The indicator of vaccination at entry (1 = vaccinated at entry; 0 = not vaccinated)
U: The minimum of: time to infection, time to refusing study vaccine after unblinding (placebo participants only), or censoring (due to loss to followup or administrative censoring).
Delta: Infection-variant category indicator, where -1 indicates a placebo participant that was unblinded and refused study vaccine; 0 indicates censoring; and = ve indicates a participant infected with variant ve (ve = 1, ..., nV).
R: The minimum of: time to unblinding, time to infection, or time to censoring.
Gamma: Indicator of the R dynamic, where 1 indicates that R is the time to unblinding and 0 indicates that R is either the time to infection or the time to censoring.
Psi: Indicator of whether a placebo subject received study vaccine, where 1 indicates that a participant that was either assigned to vaccine or was assigned to placebo, was unblinded and decided to get the study vaccine; 0 otherwise.
