Whatever the substantive merits, passing a law like this at the state level seems like a waste of everyone's time and legal fees: the food and vaccine supply chains are pretty much archetypal examples of interstate or foreign commerce, so it's really going to be the federal Congress and the federal executive branch that decide these policies. State policies running contrary to those federal decisions will get invalidated on constitutional grounds, no matter which level of government enacts its law first.
