  The Scale Invariant Vacuum (SIV) paradigm is applied to the Big-Bang
Nucleosynthesis using the known analytic expressions for the expansion factor
$a$ and the plasma temperature $T$ as functions of the SIV time $\tau$ since
the Big-Bang when $a(\tau=0)=0$. The results are compared to the known standard
BBNS model as calculated with the PRIMAT code. Potential SIV-guided deviations
from the local statistical equilibrium are explored. Overall, we find that
smaller than usual baryon and non-zero dark matter content, by a factor of
three to five times reduction, result in compatible to the standard
reproduction of the light elements abundances.
