People seem to think that getting a third mRNA vaccine dose, or "booster shot", substantially increases immunity after 4ish months from your second dose.
- Is it currently "illegal" to get one, or is it just the policy of all current pharmacies and vaccine distributors to refuse to give them?
- Is there any shortage of vaccines in the US at this point? Would getting a booster shot counter-factually cause another person to get a dose later?
- Is there chance that booster shots will become commonly available in the next month? Is it even in the Overton window of things that politicians are bothering to think about?
- Lastly -- because I assume the answer is no -- is there any reason to think that getting a third shot of a different vaccine would be biologically dangerous?
But is there any evidence that the US will actually start exporting doses if they're unused, or will they just sit around until they expire?
