Question
A novel microbe causing encephalitis emerges in humans with properties including:(i) R0 of 2,(ii) a single serotype,(iii) maintenance in bats and human primates,(iv) asymptomatic infection in > 60% of cases.If a vaccine was to be developed, which of these characteristics would argue in favour of potential eradication?Question 10Answera.i, iib.i, iiic.ii, iiid.ii, iv
Solution
The characteristics that would argue in favour of potential eradication if a vaccine was to be developed are (ii) a single serotype and (iv) asymptomatic infection in > 60% of cases.
The reason for this is that a single serotype means there is only one variation of the microbe to target, which simplifies the process of vaccine development. Additionally, if over 60% of infections are asymptomatic, it means that a large proportion of the population could be vaccinated without experiencing severe disease symptoms, which would help in controlling the spread of the microbe.
So, the answer is d. ii, iv.
