- Suppose you are designing a study to determine whether a vaccine is effective. You recruit volunteers and then assign them into two groups. Which of the following is a better way to determine if the vaccine works in a wide variety of people? (a) Recruit people from a variety of backgrounds: different ethnicities, ages, sexes, etc... and then randomly form two groups. (b) Recruit people for the study who are very similar to one another, such as married nonsmoker female nurses in their forties who don't drink with no health problems and good incomes, then randomly form two groupsVaccinating 65% of a population will provide herd immunity for a disease with which of the following reproductive rates? Pc= 1-(1/R0) Group of answer choices 2.2 Herd immunity will not be achieved for any of these reproductive rates. 4.5 3.1 5.0 Herd immunity will be achieved for all of these reproductive rates.Describe the uptake of COVID 19 vaccination in Uganda or any country of your own choice according to the diffusion of Innovations theory, and its implication to a health promoter
