Abbott’s office hasn’t yet commented on what it plans to do now. But he finds himself in a position familiar to many other Republican vaccine-mandate opponents. Lots of them stressed the emergency-use status of the previous authorization while speaking out against vaccine mandates; now the Pfizer coronavirus vaccine has an approval status similar to many other vaccines that schools and governments across the country do indeed require.
My guess is that they will just drop this as a justification and make the “freedom” argument. At that point they will have completely undermined the rationale for all vaccine mandates. Dangerous territory.
