Moderna and J&J are still authorized by CDC for "emergency" use.......which all of us who have the first two doses received.....with no FDA full approval.
See first paragraph in link below:
Get Vaccine Answers | How we know COVID-19 vaccines… | The Ad Council
The so called procedural approval process moves very slowly and inefficiently and influenced by special interest and other controlling groups.
The Moderna third dose is no less "approved" than the first two shots.....all doses are the same formulation and dosage!
The approval status is a well worn, misunderstood red herring!!!!
