What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
disease-induced immunityOther
Using a different label for natural immunity, specifically, "disease-induced immunity"
natural immunityOther
Using standard label "natural immunity"
| Study group | Role | What they receive |
|---|---|---|
| natural immunity | Placebo comparator | Label used is standard term "natural immunity" Receives: Other: natural immunity |
| disease-induced immunity | Experimental | Label used is "disease-induced immunity" Receives: Other: disease-induced immunity |
What is being measured
The primary outcome is the main question the study is designed to answer.
Opinion about forms of immunity
Participants indicate their opinion in response to question, "In your opinion, which is better: vaccine-induced immunity or natural/disease-induced immunity?" on a visual analog scale (slider) from 0-100, with 0 = "vaccine-induced immunity is much better," 50 = "both forms of immunity are equally good," 100 = "natural/disease-induced immunity is much better."
Measured: Immediately after intervention
