Transcribed Image Text:### Clinical Trial Results on the Efficacy of a New Vaccine Against SARS CoV-2
#### Study Overview
A randomized clinical trial was conducted to evaluate a new vaccine designed to protect against SARS CoV-2 infection. The study enrolled 100,000 adults who tested negative for the infection at baseline. The data presented below are based on the results after a follow-up period of six months.
#### Results Table
| Status | SARS CoV-2 Positive | SARS CoV-2 Negative | Total Subjects |
|-----------------------|---------------------|---------------------|----------------|
| **Received Vaccine** | 10 | 49,990 | 50,000 |
| **Did not receive vaccine** | 200 | 49,810 | 50,000 |
- **Received Vaccine**:
- SARS CoV-2 Positive: 10
- SARS CoV-2 Negative: 49,990
- Total Subjects: 50,000
- **Did Not Receive Vaccine**:
- SARS CoV-2 Positive: 200
- SARS CoV-2 Negative: 49,810
- Total Subjects: 50,000
#### Question
12. What is the main measure of interest in the study?
- A. Relative Risk.
- B. Odds Ratio.
- C. The fraction of disease attributable to SARS CoV-2 for exposed persons.
- D. The fraction of disease attributable to SARS CoV-2 for non-exposed persons.
This table is crucial for understanding the comparative effectiveness of the vaccine in preventing SARS CoV-2 infection among the vaccinated versus the unvaccinated groups.
