Let Pi denote the probability of getting a disease if vaccinated, and P2 denotes the probability of getting the disease if unvaccinated, then vaccine efficacy (VE) is VE = 1– P1 P2. That is, VE is a relative probability concept because Pi is divided by P2. Suppose there are n people in the vaccinated (i.e., treatment) group, and the unvaccinated (i.e., control or placebo) group is also of size n. That is, the vaccinated and unvaccinated groups are the same size. Also, suppose that 5 people in the vaccinated group contract the disease and 85 people in the unvaccinated group contract the disease Calculate the vaccine efficacy VE

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

Let Pi denote the probability of getting a disease if vaccinated, and P2 denotes the probability of
getting the disease if unvaccinated, then vaccine efficacy (VE) is
VE = 1 –
P2 .
That is, VE is a relative probability concept because Pi is divided by P2. Suppose there are n people
in the vaccinated (i.e., treatment) group, and the unvaccinated (i.e., control or placebo) group is also
of size n. That is, the vaccinated and unvaccinated groups are the same size. Also, suppose that 5
people in the vaccinated group contract the disease and 85 people in the unvaccinated group
contract the disease. Calculate the vaccine efficacy VE.
