September 8, 2021
10:52 AM
Initial RO of 3
Delta @ 6-9
RE:  effective reproductive number
RE = RO x [share of the population susceptible to the disease]
Susceptible portion of the population = [1-xv]
RE = RO [1-xv]
1 = 1 whole population
X = % people of vaccinated people
V = vaccine's effectiveness
RE = 8[1-(0.85 . 0.85]
RE = 8  [1 - 0.7225]
RE = 2.22

if all are vaccinated ?

RE =  8 [1-0.85]
RE = 8 * 0.15
RE = 1.2


Quebec vaxxed = 12,643,822
Total doses administered
12 497 942 Read the content of note no.1
(+ 10 042 Read the content of note no.2)
Population who have received at least one dose (percentage)
76.9
RE = 8 x 0.34635 OR 8 * (1 - 0.769*0.85)
RE = 2.77

RE =  2.1556
