In brief: Exact time unknown
The effectiveness studies that were published & supported approval of the vaccine efficiency were done at 28 days after dosing.
Earlier response may be possible, but the vaccine is not promoted as a way to stop secondary cases(after exposure)unless used in conjunction with oral or injected antibiotics for those considered at risk.
