From 1912 to 1928, the contact number for measles in the U.S. was 12.8. If we assume that Ro is still 12.8 and that inoculation is 100% effective -- everyone inoculated obtains immunity from the disease -- what fraction of the population must be inoculated to prevent an epidemic?

Sagot :

Answer:

70-85%

Explanation:

Inoculation is basically developing herd immunity in a given population so that there is no more spread of the virus and the pandemic is prevented.

It is generally believed that if 75-80% people are inoculated then epidemic can be prevented.
