Question
Transcribed Image Text:During the development process of a vaccine for the newly discovered Sars-COV-2 (COVID-
19) virus, pharmaceutical companies developed two potential vaccine candidates,
BNT162b2 and Ad26.COV2. Some researchers postulated that BNT162b2 will be more ef-
fective than Ad26.COV2 because only BNT162b2 directly targets the protein-manufactur-
ing mechanisms in the cell.
To test this claim, researchers proposed an experiment in which data will be collected
about the efficacy of the two vaccine candidates. In the proposed study, two groups of mice
will be randomly assigned one of the vaccine candidates and then infected with the virus.
Data about the severity of symptoms in each group will then be collected.
Which of the following describes a potential method for measuring the dependent variable
in this experimental design?
A
B
с
D
measure the amount of virus administered to each group
measure the time between vaccine administration and virus infection in each group
measure the amount of vaccine administered to each group
measure the number of patient fatalities following vaccine administration in each group
