In my moment of desperation, I received clarity.
What does the FDA approval do to the other vaccines? It renders them useless without the FDA approval. How many of the other vaccines are going to get tossed in the trash and expire due to people wanting to get the only FDA approved one? Billions of dollars thrown away.
Maybe the Kamala-Joe administration could send the billions of dollars worth of vax to the Taliban, in exchange for the hostages. I'm sure they would appreciate it.
