n0S	births into the S compartment, not vaccinated	(1, 0, 0, 0)
nSE	number of people transitioning from S to E	(−1, 1, 0, 0)
nS0	number of deaths leaving S	(−1, 0, 0, 0)
nEI	number of people transitioning from E to I	(0, −1, 1, 0)
nE0	number of deaths leaving E	(0, −1, 0, 0)
n0I	number of imported infections	(0, 0, 1, 0)
nIR	number of people transitioning from I to R	(0, 0, −1, 1)
