I agree - the media, FDA, and medical community does a TERRIBLE job of communicating scientific data. They tend to either say "just trust us" or focus way too much on outliers.
As far as EUA is concerned, can you think of any other disease in your lifetime that's had the impact that Covid-19 has?
The reason why EUA isn't used more often is because it's not necessary - basically, most other diseases that might benefit from it aren't affecting (ie, hospitalizing or killing) enough people.
However, if you go to the FDA website, you can see what other drugs/treatments/vaccines have been given EUA. The list includes a variety of diagnostics for Zika and Ebola, antivirals for H1N1, and an Anthrax vaccine and treatment.
The FDA also issued EAU for the use of Remdesivir for treatment of Covid-19.
EUA was never meant to be used as a fast tract for just any drug, treatment, or vaccine. It was put in place after 9/11 as a direct response to the fear of a bio-terror attack. In the time since then, it became obvious it would be useful for a pandemic, but we haven't had one of this magnitude. The closest we came was the H1N1 outbreak (during which the EAU was invoked). MERS, Ebola, and Zika just never became major issues in the US.
Also, in order for EAU to be invoked, some very specific criteria have to be met. Invoking EUA is not a decision the FSA makes on its own - it also involves the secretaries of HHS, Homeland Security, and/or DoD.
I will say though, the cognitive dissonance between people screaming for (or against) certain EUA (or non-FDA approved) Covid-19 treatments like Remdesivir and Hydroxychloroquine but arguing strongly against (or for) the vaccine is just mind-boggling.
The woman I know who insisted the Covid vaccine kills more people than car accidents held this position. She's adamantly against the mRNA vaccines, but she went on a rant about how the CDC/FDA/medical community spoke out against hydroxychloroquine as a treatment simply because they didn't like Trump.
I hate what this has turned into (not this thread - this whole situation).
