CAIE A Level Biology 9700 · Immunity
Table 1 shows the percentage of the population vaccinated and the number of reported cases per 100 000 people in two regions during an outbreak of disease Y.
| Region | Percentage of population vaccinated | Number of reported cases per 100 000 people |
|---|---|---|
| A | 94 | 25 |
| B | 38 | 1450 |
Compare the roles of vaccination and monoclonal antibodies in controlling and treating disease Y. Use the information in Table 1 and your knowledge of immunity.
7 marks, so the mark scheme is looking for about 7 separate creditworthy points. Making the same point twice in different words earns it once.
Compare means: Give similarities or differences between two things, and say which side each point belongs to. Write each point as a pair, for example: A is X, whereas B is Y. Two separate descriptions rarely earn the marks.
