Israel has given 3 million booster shots. Israel requires three shots for everyone over 12. Green passes for people who have not had a booster shot.
The Pfizer company is illegally conducting phases 1, 2 and 3 simultaneously so Pfizer doses in the US (not sure about Israel) can be zero, 5 mcgs, 10 mcgs or 30 mcgs. But boosters are 30 mcgs. Contrast that with Moderna which has 100 mcgs of mRNA nucleosides.
