Step-by-step explanation:
Herd immunity or community immunity is the immunity seen after vaccination of a population wherein the large portion of the population becomes immune to the pathogen. It depends on vaccine efficacy and vaccination rate.
The reproduction number R_o is a factor indicating the number of people that can be infected by the person with the disease. If Ro=5 then one infected person can infect 5 people with Polio virus.
V_c= q_c/E
V_c= Vaccine coverage
q_c= herd immunity threshold
E= Vaccine efficacy= 99%=0.99
![q_c=1-1/R_o= 1-1/5=0.8](https://tex.z-dn.net/?f=q_c%3D1-1%2FR_o%3D%201-1%2F5%3D0.8)
V_c= q_c/E
V_c= 0.8/0.99= 0.808= 0.81
Thus, 81% coverage or vaccination for Polio is required to stop spread of Polio in the population.
