In multigroup.vaccine: Analyze Outbreak Models of Multi-Group Populations with Vaccination

Calculate reproduction number for a multigroup model with a given state of vaccination and immunity

Description

Calculate reproduction number for a multigroup model with a given state of vaccination and immunity

Usage

vaxrepnum(meaninf, popsize, trmat, initR, initV, vaxeff)

Arguments

meaninf	mean infectious period with same time units as trmat
popsize	the population size of each group
trmat	matrix of group-to-group (column-to-row) transmission rates
initR	initial number of each group already infected and immune
initV	initial number of each group vaccinated
vaxeff	effectiveness (0 to 1) of vaccine in producing immunity to infection

Value

the reproduction number

Examples

meaninf <- 7
popsize <- c(200, 800)
initR <- c(0, 0)
initV <- c(0, 0)
vaxeff <- 1
trmat <- matrix(c(0.63, 0.31, 0.19, 1.2), 2, 2)
vaxrepnum(meaninf, popsize, trmat, initR, initV, vaxeff)
vaxrepnum(meaninf, popsize, trmat, initR, initV = c(160, 750), vaxeff)
