It looks like Dr. Birx believed the efficacy of the MRNA vaccines was a half-baked theory:
How does that comport with your knowledge of virology?
I’ll leave you and your new pal Birx to sort out what she meant. It looks like she was doing what most people do, make up something that sounds good and then run with it, the facts be damned.
“How does that comport with your knowledge of virology?”
Well I’m sure that from your own extensive training you know that vaccines teach your immune system to fight a particular pathogen. That’s what they have done since Edward Jenner used cowpox inoculations.
They aren’t a guarantee that you won’t get sick. Flu vaccines are only 40%-60% effective. Yet they are still vaccines.
