In a community, 60 % of individuals are vaccinated against disease Y. The vaccine reduces susceptibility to infection by 70 % and, if infection occurs, reduces the infectiousness of the host by 50 %. If the basic reproduction number of disease Y in a completely susceptible, unvaccinated population is \(R_{0}\), calculate the effective reproduction number \(R_{e}\) in the whole community. Express \(R_{e}\) as a multiple of \(R_{0}\).

Correct Answer A. \(0.406\,R_{0}\)

B. \\(0.35\\,R_{0}\\)

C. \\(0.70\\,R_{0}\\)

D. \\(0.55\\,R_{0}\\)
