part (a). 32. Vaccination coverage Suppose we modify the function in Example 5 by introducing vaccination to control the probability of an outbreak of the disease. We want to know the fraction of the population that we have to vaccinate to achieve a target outbreak probability. If v is the vaccination fraction, then the outbreak probability as a function of v is P= 1- Ro( 1 - v) Find the inverse of this function to obtain the vaccination coverage needed for any given target outbreak probability
