Placebo can have an effect on side effects.
- cwhiz 6y agoAre they testing for side effects in all three stages? I thought the first two trials were for safety and the third was for efficacy. Is that incorrect?
- tcoff91 6y agoThey're absolutely monitoring side effects during phase 3. some safety effects can be rare enough that they don't show up in phase 1/2.
- cwhiz 6y agoOkay. I’m still having a hard time understanding how placebo helps them test for side effects.
- Izkata 6y agoI imagine: If a given side-effect occurs at the same rate in both groups, it's unlikely to be caused by the vaccine and is more likely to be psychosomatic.
- chrisrogers 6y agoPsychosomatic, or the result of administering an IV shot, or environmental.
- ksk 6y agoData on adverse reactions is captured by the CDC/FDA/HHS throughout the lifecycle of the vaccine, from all the phases of clinical trials to its use in the general population. Its required by law.
