You're right. They'll never give up their shield from liability.
From the FDA release (sounds familiar?):
"Spikevax has the same formulation as the EUA Moderna COVID-19 Vaccine and is administered as a primary series of two doses, one month apart. Spikevax can be used interchangeably with the EUA Moderna COVID-19 Vaccine to provide the COVID-19 vaccination series. Moderna COVID-19 Vaccine remains available under EUA as a two-dose primary series for individuals 18 years of age and older, as a third primary series dose for individuals 18 years of age and older who have been determined to have certain kinds of immunocompromise, and as a single booster dose for individuals 18 years of age and older at least five months after completing a primary series of the vaccine. It is also authorized for use as a heterologous (or “mix and match”) single booster dose for individuals 18 years of age and older following completion of primary vaccination with a different available COVID-19 vaccine."
You're right. They'll never give up their shield from liability.
