Researchers look for expected reactions to the vaccine—which could include anticipated adverse events, like headache, muscle pain, redness and swelling at the injection site or low-grade fevers—as well as serious adverse events, which are expected to be rare, over the entire duration of the study. Phase 2a studies aim to determine the most effective dose, and expand the safety experience with the vaccine. (Some vaccine clinical trials have included many thousands, such as is occurring with the COVID-19 vaccine trials, which include tens of thousands.) The principle objectives in phase III are to: 1. demonstrate the safety and effectiveness of the new medicine or vaccine in the typical patient likely to use it 2. confirm effective dosing levels 3. identify side effects or reasons why the treatment should not be given to people with another condition (known … The data set included 406,038 trials (of which 185,994 were unique) 1 and well over Phase 3 trials can sometimes take years.
