Estimated vaccine effectiveness (95%CI) estimates from household secondary attack rates.

Vaccine effectiveness	Full Vaccination	Partial Vaccination
VE I,p	56.6% (28.7%–73.6%)	27.5% (−6.4%–50.7%)
VE S,p	70.3% (59.3%–78.4%)	43.9% (21.8%–59.7%)
VE T,p	86.8% (76.7%–92.5%)	59.9% (34.4%–75.5%)

VE_I,p: vaccine effectiveness for infectiousness based on the transmission probability p; VE_S,p: vaccine effectiveness for susceptibility; VE_T,p: total vaccine effectiveness
