| Response | N | % |
|---|---|---|
| The percentage of individuals who do not develop Covid-19 among those vaccinated 1 – ARV [Target error] |
192 | 64 |
| The percentage of individuals who do not develop Covid-19 among those vaccinated minus the percentage of individuals who do develop Covid-19 among those vaccinated (1 – ARV) – ARV |
49 | 16 |
| The difference between the percentages of individuals who do not and who do develop Covid-19 among those vaccinated minus the difference between the percentages of individuals who do not and who do develop Covid-19 among those not vaccinated ((1 – ARV) – ARV) – ((1 – ARU) – ARU) |
28 | 9 |
| The percentage of individuals who do not develop Covid-19 among those vaccinated minus the percentage of individuals who do not develop Covid-19 among those not vaccinated, divided by the latter percentage ((1 – ARV) – (1 – ARU))/(1 – ARU) = (ARU – ARV)/(1 – ARU) |
15 | 5 |
| The percentage of individuals who do develop Covid-19 among those not vaccinated minus the percentage of individuals who do develop Covid-19 among those vaccinated, divided by the former percentage (ARU – ARV)/ARU [Correct response] |
