The FDA seems to be ghosting Moderna.
Moderna submitted the necessary data for full approval about a month after Pfizer did, but AFAIK, the FDA has done nothing about it - no approval, no refusal, no request for more data, no meeting, just silence. The Pfizer/BioNTech vaccine received full approval for ages 16 and above several months ago.
Moderna submitted the test data for and requested EUA for EUA for ages 12-17, and FDA has done nothing about it - no approval, no refusal, etc. etc. etc..
WRT boosters, Pfizer received EUA for a couple of specific populations. Moderna submitted their test data and ... crickets. J&J submitted their test data very recently, and have gotten push-back about their test method and data quality.
I'm not CT-minded, but FDA silence toward Moderna sort of looks like Bidenesque retribution for having worked closely with the Trump Administration and OWS.
