If it such a great vaccine why has it not yet approved as one. Note they are not forcing anyone to get it but if you do not you will not be able to do anything making it your choice.
Because they're in the middle of Phase 3 of the trials which do have a Phase 4.
Pfizer's clinical trial; https://clinicaltrials.gov/ct2/show/study/NCT04368728
Moderna's COVID-19 Clinical Trial Phase 3 at clinicaltrials.gov; https://clinicaltrials.gov/ct2/show/study/NCT04470427
Pfizer's Primary Completion Date; Nov 2021 -- Study Completion Date; May 2023
Moderna's Phase 3 Completion Date; Oct 2022.
Phase 3 trials include healthy people 18-55/65 who have not had covid and pregnant women are excluded as well. That's for the trials though. In the public, there are no exclusions to who's getting the shot.
