Answered by AI

How does mRNA-1273.211 compare to other similar treatments?

"The first study of mRNA-1273.211 took place in 2020 at Kaiser Permanente Washington Health Research Institute - Vaccines and Infectious Diseases. There have been a total of 8 completed clinical trials since then, with 28 more currently underway across the globe; many of these are being conducted out of Sacramento, California."

Answered by AI

Are people with the relevant medical condition still able to sign up for this experiment?

"The clinical trial in question is not presently seeking participants, as per the information available on clinicaltrials.gov. This specific study was first posted on 5/28/2021 and was last edited on 11/16/2022; however, there are 1147 other clinical trials that are actively recruiting patients right now."

Answered by AI

Is this a unique or innovative clinical trial?

"A search of available data reveals that there are 28 ongoing studies for mRNA-1273.211 in 219 cities across 22 countries. The first trial was sponsored by ModernaTX, Inc. and completed its Phase 1 drug approval stage in 2020 after involving 120 patients. In the two years since the initial study, 8 more trials have been conducted."
