Question

Check out the internet for values of Ro for the flu, HIV, and Ebola (mention your source). What is the percentage of the population that need to be vaccinated (if there is a vaccination) for each disease to avoid an epidemic?

Answer 1

Disease Ro value refrence Ebola 1.5-1.9 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4347917 Influenza 1.4-2.8 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7095311 HIV 2-5 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3880255/

To find out population to be vaccinated to get herd immunity following fromula can be used..... People to be vaccinated then multiply it by 100 to get percent of population .

Here , I took average value for each Ro to find out population to be vaccinated as given below

Disease	Ro	population to be vaccinated
Ebola	1.7	42%
Influenza	2.1	53%
HIV	3.5	72%
