Verified Answer
Which of the following statements is incorrect regarding Herd Immunit...
Immunity of population can develop either through herd immunity or through vaccination.
Option a is correct. Herd immunity is the immunity which the population of a region develops after getting infected with a particular microbes (virus, bacteria etc). How much percentage of the population that should get infected to develop herd immunity depends on the transmission rate of the infection. For ex: In case of Measles outbreak, the transmission rate was 10 i.e. one infected person can infect 10 more people on an average. Then 90 percent of the population should get infected to develop herd immunity in the population. Similarly, in case of Covid disease, the transmission rate is 2 i.e. one infected person can on an average transmit to two more people. Hence, infection among 40 percent of the population will develop herd immunity.
Option b is correct. From as explained above, it is concluded that the more infectious a disease is, the greater the population should first get infected with the virus to develop herd immunity.
Option c is correct. Herd Immunity is typically viewed as a preventive strategy in vaccination programmes.
Option d is incorrect. When a population develops herd immunity, it implies the population is immune to that infection. However, it is wrong to conclude that no one will get infected further. The infection will still take place but only a few cases and controlled infection will be there.
